altair.Chart#

class altair.Chart(data=Undefined, encoding=Undefined, mark=Undefined, width=Undefined, height=Undefined, **kwargs)#

Create a basic Altair/Vega-Lite chart.

Although it is possible to set all Chart properties as constructor attributes, it is more idiomatic to use methods such as mark_point(), encode(), transform_filter(), properties(), etc. See Altair’s documentation for details and examples: http://altair-viz.github.io/.

Parameters:
dataData

An object describing the data source

markAnyMark

A MarkDef or CompositeMarkDef object, or a string describing the mark type (one of “arc”, “area”, “bar”, “circle”, “geoshape”, “image”, “line”, “point”, “rule”, “rect”, “square”, “text”, “tick”, “trail”, “boxplot”, “errorband”, and “errorbar”).

encodingFacetedEncoding

A key-value mapping between encoding channels and definition of fields.

autosizeanyOf(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

backgroundstring

CSS color property to use as the background of visualization.

Default value: none (transparent)

configConfig

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

descriptionstring

Description of this mark for commenting purpose.

heightfloat

The height of a visualization.

namestring

Name of the visualization for later reference.

paddingPadding

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

projectionProjection

An object defining properties of geographic projection. Works with “geoshape” marks and “point” or “line” marks that have a channel (one or more of “X”, “X2”, “Y”, “Y2”) with type “latitude”, or “longitude”.

selectionMapping(required=[])

A key-value mapping between selection names and definitions.

titleanyOf(string, TitleParams)

Title for the plot.

transformList(Transform)

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

widthfloat

The width of a visualization.
