altair.FacetChart

class altair.FacetChart(data=Undefined, spec=Undefined, facet=Undefined, **kwargs)

A Chart with layers within a single panel Mapping(required=[data, facet, spec])

Attributes:

data : Data

An object describing the data source

facet : anyOf(FacetFieldDef, FacetMapping)

Definition for how to facet the data. One of: 1) a field definition for faceting the plot by one field 2) An object that maps row and column channels to their field definitions

spec : anyOf(LayerSpec, FacetedUnitSpec)

A specification of the view that gets faceted.

align : anyOf(LayoutAlign, RowColLayoutAlign)

The alignment to apply to grid rows and columns. The supported string values are "all", "each", and "none".

• For "none", a flow layout will be used, in which adjacent subviews are simply placed one after the other.
• For "each", subviews will be aligned into a clean grid structure, but each row or column may be of variable size.
• For "all", subviews will be aligned and each row or column will be sized identically based on the maximum observed size. String values for this property will be applied to both grid rows and columns.

Alternatively, an object value of the form {"row": string, "column": string} can be used to supply different alignments for rows and columns.

Default value: "all".

autosize : anyOf(AutosizeType, AutoSizeParams)

Sets how the visualization size should be determined. If a string, should be one of "pad", "fit" or "none". Object values can additionally specify parameters for content sizing and automatic resizing. "fit" is only supported for single and layered views that don’t use rangeStep.

Default value : pad

background : string

CSS color property to use as the background of the entire view.

Default value: none (transparent)

bounds : enum(‘full’, ‘flush’)

The bounds calculation method to use for determining the extent of a sub-plot. One of full (the default) or flush.

• If set to full, the entire calculated bounds (including axes, title, and legend) will be used.
• If set to flush, only the specified width and height values for the sub-view will be used. The flush setting can be useful when attempting to place sub-plots without axes or legends into a uniform grid structure.

Default value: "full"

center : anyOf(boolean, RowColboolean)

Boolean flag indicating if subviews should be centered relative to their respective rows or columns.

An object value of the form {"row": boolean, "column": boolean} can be used to supply different centering values for rows and columns.

Default value: false

columns : float

The number of columns to include in the view composition layout.

Default value : undefined – An infinite number of columns (a single row) will be assumed. This is equivalent to hconcat (for concat ) and to using the column channel (for facet and repeat ).

Note :

1. This property is only for:

• the general (wrappable) concat operator (not hconcat / vconcat )
• the facet and repeat operator with one field/repetition definition (without row/column nesting)

2) Setting the columns to 1 is equivalent to vconcat (for concat ) and to using the row channel (for facet and repeat ).

config : Config

Vega-Lite configuration object. This property can only be defined at the top-level of a specification.

datasets : Datasets

A global data store for named datasets. This is a mapping from names to inline datasets. This can be an array of objects or primitive values or a string. Arrays of primitive values are ingested as objects with a data property.

description : string

Description of this mark for commenting purpose.

name : string

Name of the visualization for later reference.

padding : Padding

The default visualization padding, in pixels, from the edge of the visualization canvas to the data rectangle. If a number, specifies padding for all sides. If an object, the value should have the format {"left": 5, "top": 5, "right": 5, "bottom": 5} to specify padding for each side of the visualization.

Default value : 5

resolve : Resolve

Scale, axis, and legend resolutions for view composition specifications.

spacing : anyOf(float, RowColnumber)

The spacing in pixels between sub-views of the composition operator. An object of the form {"row": number, "column": number} can be used to set different spacing values for rows and columns.

Default value : Depends on "spacing" property of the view composition configuration ( 20 by default)

title : anyOf(string, TitleParams)

Title for the plot.

transform : List(Transform)

An array of data transformations such as filter and new field calculation.

usermeta : Mapping(required=[])

Optional metadata that will be passed to Vega. This object is completely ignored by Vega and Vega-Lite and can be used for custom metadata.

$schema : string

URL to JSON schema for a Vega-Lite specification. Unless you have a reason to change this, use https://vega.github.io/schema/vega-lite/v3.json. Setting the $schema property allows automatic validation and autocomplete in editors that support JSON schema.

If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColor : Color

The color of the tick label, can be in hex color code or regular color name.

labelFlush : anyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffset : float

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

Attributes:

bandPosition : float

An interpolation fraction indicating where, for band scales, axis ticks should be positioned. A value of 0 places ticks at the left edge of their bands. A value of 0.5 places ticks in the middle of their bands.

Default value: 0.5

domain : boolean

A boolean flag indicating if the domain (the axis baseline) should be included as part of the axis.

Default value: true

domainWidth : float

Stroke width of axis domain line

Default value: 1

grid : boolean

A boolean flag indicating if grid lines should be included as part of the axis

Default value: true for continuous scales that are not binned; otherwise, false.

gridColor : Color

Color of gridlines.

Default value: "lightGray".

gridDash : List(float)

An array of alternating [stroke, space] lengths for dashed grid lines.

gridDashOffset : float

The pixel offset at which to start drawing with the grid dash array.

gridOpacity : float

The stroke opacity of grid (value between [0,1])

Default value: 1

gridWidth : float

The grid width, in pixels.

Default value: 1

labelAlign : Align

Horizontal text alignment of axis tick labels, overriding the default setting for the current axis orientation.

labelAngle : float

The rotation angle of the axis labels.

Default value: -90 for nominal and ordinal fields; 0 otherwise.

labelBaseline : TextBaseline

Vertical text baseline of axis tick labels, overriding the default setting for the current axis orientation. Can be "top", "middle", "bottom", or "alphabetic".

labelBound : anyOf(float, boolean)

Indicates if labels should be hidden if they exceed the axis range. If false (the default) no bounds overlap analysis is performed. If true, labels will be hidden if they exceed the axis range by more than 1 pixel. If this property is a number, it specifies the pixel tolerance: the maximum amount by which a label bounding box may exceed the axis range.

Default value: false.

labelColor : Color

The color of the tick label, can be in hex color code or regular color name.

labelFlush : anyOf(boolean, float)

Indicates if the first and last axis labels should be aligned flush with the scale range. Flush alignment for a horizontal axis will left-align the first label and right-align the last label. For vertical axes, bottom and top text baselines are applied instead. If this property is a number, it also indicates the number of pixels by which to offset the first and last labels; for example, a value of 2 will flush-align the first and last labels and also push them 2 pixels outward from the center of the axis. The additional adjustment can sometimes help the labels better visually group with corresponding axis ticks.

Default value: true for axis of a continuous x-scale. Otherwise, false.

labelFlushOffset : float

Indicates the number of pixels by which to offset flush-adjusted labels. For example, a value of 2 will push flush-adjusted labels 2 pixels outward from the center of the axis. Offsets can help the labels better visually group with corresponding axis ticks.

If set to true or "parity", a strategy of removing every other label is used (this works well for standard linear axes). If set to "greedy", a linear scan of the labels is performed, removing any labels that overlaps with the last visible label (this often works better for log-scaled axes).

Default value: true for non-nominal fields with non-log scales; "greedy" for log scales; otherwise false.

labelPadding : float

The padding, in pixels, between axis and text labels.

tickDashOffset : float

The pixel offset at which to start drawing with the tick mark dash array.

tickExtra : boolean

Boolean flag indicating if an extra axis tick should be added for the initial position of the axis.

Use in conjunction with "bandPosition": 1 and an axis "padding" value of 0.

tickOffset : float

Position offset in pixels to apply to ticks, labels, and gridlines.

tickOpacity : float

Opacity of the ticks.

tickRound : boolean

For line and trail marks, this order property can be set to null or false to make the lines use the original order in the data sources.

orient : Orientation

The orientation of a non-stacked bar, tick, area, and line charts. The value is either horizontal (default) or vertical.

• For bar, rule and tick, this determines whether the size of the bar and tick

should be applied to x or y dimension. * For area, this property determines the orient property of the Vega output. * For line and trail marks, this property determines the sort order of the points in

the line

if config.sortLineBy is not specified. For stacked charts, this is always determined by the orientation of the stack; therefore explicitly specified value will be ignored.

• plotting shapes: "circle", "square", "cross", "diamond", "triangle-up", "triangle-down", "triangle-right", or "triangle-left".
• the line symbol "stroke"
• centered directional shapes "arrow", "wedge", or "triangle"
• a custom SVG path string (For correct sizing, custom shape paths should be defined within a square bounding box with coordinates ranging from -1 to 1 along both the x and y dimensions.)

Default value: "circle"

size : float

Default size for marks.

• For point / circle / square, this represents the pixel area of the marks. For example: in the case of circles, the radius is determined in part by the square root of the size value.
• For bar, this represents the band size of the bar, in pixels.
• For text, this represents the font size, in pixels.

Default value: 30 for point, circle, square marks; rangeStep - 1 for bar marks with discrete dimensions; 5 for bar marks with continuous dimensions; 11 for text marks.

theta : float

Polar coordinate angle, in radians, of the text label from the origin determined by the x and y properties. Values for theta follow the same convention of arc mark startAngle and endAngle properties: angles are measured in radians, with 0 indicating “north”.

tooltip : anyOf(string, TooltipContent, None)

The tooltip text string to show upon mouse hover or an object defining which fields should the tooltip be derived from.

• If tooltip is {"content": "encoding"}, then all fields from encoding will be used.
• If tooltip is {"content": "data"}, then all fields that appear in the highlighted data point will be used.
• If set to null, then no tooltip will be used.

alt.AggregateTransform

underlying transform object

Examples

The aggregate transform allows you to specify transforms directly using the same shorthand syntax as used in encodings:

>>> import altair as alt
>>> chart1 = alt.Chart().transform_aggregate(
...     mean_acc='mean(Acceleration)',
...     groupby=['Origin']
... )
>>> print(chart1.transform[0].to_json())  
{
  "aggregate": [
    {
      "as": "mean_acc",
      "field": "Acceleration",
      "op": "mean"
    }
  ],
  "groupby": [
    "Origin"
  ]
}

It also supports including AggregatedFieldDef instances or dicts directly, so you can create the above transform like this:

>>> chart2 = alt.Chart().transform_aggregate(
...     [alt.AggregatedFieldDef(field='Acceleration', op='mean',
...                             **{'as': 'mean_acc'})],
...     groupby=['Origin']
... )
>>> chart2.transform == chart1.transform
True

Returns:

self : Chart object

returns chart to allow for chaining

See also

>>> chart.transform[0]
BinTransform({
  as: 'x_binned',
  bin: True,
  field: 'x'
})

>>> chart = alt.Chart().transform_bin("x_binned", "x",
...                                   bin=alt.Bin(maxbins=10))
>>> chart.transform[0]
BinTransform({
  as: 'x_binned',
  bin: BinParams({
    maxbins: 10
  }),
  field: 'x'
})

Examples

>>> import altair as alt
>>> from altair import datum, expr

>>> chart = alt.Chart().transform_calculate(y = 2 * expr.sin(datum.x))
>>> chart.transform[0]
CalculateTransform({
  as: 'y',

>>> chart = alt.Chart().transform_calculate(**kwds)
>>> chart.transform[0]
CalculateTransform({
  as: 'y',

Add an ImputeTransform to the schema.

Parameters:

impute : string

The data field for which the missing values should be imputed.

key : string

A key field that uniquely identifies data objects within a group. Missing key values (those occurring in the data but not in the current group) will be imputed.

frame : List(anyOf(None, float))

A frame specification as a two-element array used to control the window over which the specified method is applied. The array entries should either be a number indicating the offset from the current data object, or null to indicate unbounded rows preceding or following the current data object. For example, the value [-5, 5] indicates that the window should include five objects preceding and five objects following the current object. Default value: : [null, null] indicating that the window includes all objects.

groupby : List(string)

An optional array of fields by which to group the values. Imputation will then be performed on a per-group basis.

keyvals : anyOf(List(Mapping(required=[])), ImputeSequence)

Defines the key values that should be considered for imputation. An array of key values or an object defining a number sequence. If provided, this will be used in addition to the key values observed within the input data. If not provided, the values will be derived from all unique values of the key field. For impute in encoding, the key field is the x-field if the y-field is imputed, or vice versa. If there is no impute grouping, this property must be specified.

method : ImputeMethod

The imputation method to use for the field value of imputed data objects. One of value, mean, median, max or min. Default value: "value"

value : Mapping(required=[])

The field value to use when the imputation method is "value".

returns chart to allow for chaining

See also

alt.LookupTransform

underlying transform object

Attributes:

as_ : anyOf(string, List(string))

The field or fields for storing the computed formula value. If from.fields is specified, the transform will use the same names for as. If from.fields is not specified, as has to be a string and we put the whole object into the data under the specified name.

from_ : LookupData

Secondary data reference.

lookup : string

Key in primary data source.

default : string

The default value to use if lookup fails. Default value: null

transform_sample(sample=1000)

alt.SampleTransform

underlying transform object

transform_stack(as_, stack, groupby, offset=Undefined, sort=Undefined)

Add a StackTransform to the schema.

Parameters:

as_ : anyOf(string, List(string))

Output field names. This can be either a string or an array of strings with two elements denoting the name for the fields for stack start and stack end respectively. If a single string(eg.”val”) is provided, the end field will be “val_end”.

stack : string

The field which is stacked.

groupby : List(string)

The data fields to group by.

offset : enum(‘zero’, ‘center’, ‘normalize’)

Mode for stacking marks. Default: ‘zero’.

sort : List(SortField)

transform_timeunit(as_=Undefined, field=Undefined, timeUnit=Undefined, **kwargs)

Add a TimeUnitTransform to the schema.

Parameters:

as_ : string

The output field to write the timeUnit value.

field : string

The data field to apply time unit.

timeUnit : TimeUnit

**kwargs

transforms can also be passed by keyword argument; see Examples

Returns:

self : Chart object

returns chart to allow for chaining

See also

alt.TimeUnitTransform

underlying transform object

Examples

>>> import altair as alt
>>> from altair import datum, expr

>>> chart = alt.Chart().transform_timeunit(month='month(date)')
>>> chart.transform[0]
TimeUnitTransform({
  as: 'month',
  field: 'date',
  timeUnit: 'month'
})

It’s also possible to pass the TimeUnitTransform arguments directly; this is most useful in cases where the desired field name is not a valid python identifier:

>>> kwds = {'as': 'month', 'timeUnit': 'month', 'field': 'The Month'}
>>> chart = alt.Chart().transform_timeunit(**kwds)
>>> chart.transform[0]
TimeUnitTransform({
  as: 'month',
  field: 'The Month',
  timeUnit: 'month'
})

As the first form is easier to write and understand, that is the recommended method.

transform_window(window=Undefined, frame=Undefined, groupby=Undefined, ignorePeers=Undefined, sort=Undefined, **kwargs)

Add a WindowTransform to the schema

Parameters:

window : List(WindowFieldDef)

The definition of the fields in the window, and what calculations to use.

frame : List(anyOf(None, float))

A frame specification as a two-element array indicating how the sliding window should proceed. The array entries should either be a number indicating the offset from the current data object, or null to indicate unbounded rows preceding or following the current data object. The default value is [null, 0], indicating that the sliding window includes the current object and all preceding objects. The value [-5, 5] indicates that the window should include five objects preceding and five objects following the current object. Finally, [null, null] indicates that the window frame should always include all data objects. The only operators affected are the aggregation operations and the first_value, last_value, and nth_value window operations. The other window operations are not affected by this.

Default value: : [null, 0] (includes the current object and all preceding objects)

groupby : List(string)

The data fields for partitioning the data objects into separate windows. If unspecified, all data points will be in a single group.

ignorePeers : boolean

Indicates if the sliding window frame should ignore peer values. (Peer values are those considered identical by the sort criteria). The default is false, causing the window frame to expand to include all peer values. If set to true, the window frame will be defined by offset values only. This setting only affects those operations that depend on the window frame, namely aggregation operations and the first_value, last_value, and nth_value window operations.

Default value: false

sort : List(SortField)

A sort field definition for sorting data objects within a window. If two data objects are considered equal by the comparator, they are considered “peer” values of equal rank. If sort is not specified, the order is undefined: data objects are processed in the order they are observed and none are considered peers (the ignorePeers parameter is ignored and treated as if set to true ).

**kwargs

transforms can also be passed by keyword argument; see Examples

Examples

A cumulative line chart

>>> import altair as alt
>>> import numpy as np
>>> import pandas as pd
>>> data = pd.DataFrame({'x': np.arange(100),
...                      'y': np.random.randn(100)})
>>> chart = alt.Chart(data).mark_line().encode(
...     x='x:Q',
...     y='ycuml:Q'
... ).transform_window(
...     ycuml='sum(y)'
... )
