0- interpolate
The line interpolation method to use for line and area marks. One of the following:
"linear": piecewise linear segments, as in a polyline."linear-closed": close the linear segments to form a polygon."step": alternate between horizontal and vertical segments, as in a step function."step-before": alternate between vertical and horizontal segments, as in a step function."step-after": alternate between horizontal and vertical segments, as in a step function."basis": a B-spline, with control point duplication on the ends."basis-open": an open B-spline; may not intersect the start or end."basis-closed": a closed B-spline, as in a loop."cardinal": a Cardinal spline, with control point duplication on the ends."cardinal-open": an open Cardinal spline; may not intersect the start or end, but will intersect other control points."cardinal-closed": a closed Cardinal spline, as in a loop."bundle": equivalent to basis, except the tension parameter is used to straighten the spline."monotone": cubic interpolation that preserves monotonicity in y.
- invalid
Invalid data mode, which defines how the marks and corresponding scales should represent invalid values (
nullandNaNin continuous scales without defined output for invalid values)."filter"— Exclude all invalid values from the visualization’s marks and scales. For path marks (for line, area, trail), this option will create paths that connect valid points, as if the data rows with invalid values do not exist."break-paths-filter-domains"— Break path marks (for line, area, trail) at invalid values. For non-path marks, this is equivalent to"filter". All scale domains will exclude these filtered data points."break-paths-show-domains"— Break paths (for line, area, trail) at invalid values. Hide invalid values for non-path marks. All scale domains will include these filtered data points (for both path and non-path marks)."show"ornull— Show all data points in the marks and scale domains. Each scale will use the output for invalid values defined inconfig.scale.invalidor, if unspecified, by default invalid values will produce the same visual values as zero (if the scale includes zero) or the minimum value (if the scale does not include zero)."break-paths-show-path-domains"(default) — This is equivalent to"break-paths-show-domains"for path-based marks (line/area/trail) and"filter"for non-path marks.
Note: If any channel’s scale has an output for invalid values defined in
config.scale.invalid, all values for the scales will be considered “valid” since they can produce a reasonable output for the scales. Thus, fields for such channels will not be filtered and will not cause path breaks.- limit
The maximum length of the text mark in pixels. The text value will be automatically truncated if the rendered size exceeds the limit.
Default value:
0– indicating no limit- lineBreak
A delimiter, such as a newline character, upon which to break text strings into multiple lines. This property is ignored if the text is array-valued.
- lineHeight
The line height in pixels (the spacing between subsequent lines of text) for multi-line text marks.
- opacity
The overall opacity (value between [0,1]).
Default value:
0.7for non-aggregate plots withpoint,tick,circle, orsquaremarks or layeredbarcharts and1otherwise.- order
For line and trail marks, this
orderproperty can be set tonullorfalseto make the lines use the original order in the data sources.- orient
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.sortLineByis not specified. For stacked charts, this is always determined by the orientation of the stack; therefore explicitly specified value will be ignored.
- outerRadius
The outer radius in pixels of arc marks.
outerRadiusis an alias forradius.Default value:
0- padAngle
The angular padding applied to sides of the arc, in radians.
- radius
For arc mark, the primary (outer) radius in pixels.
For text marks, polar coordinate radial offset, in pixels, of the text from the origin determined by the
xandyproperties.Default value:
min(plot_width, plot_height)/2- radius2
The secondary (inner) radius in pixels of arc marks.
Default value:
0- shape
Shape of the point marks. Supported values include:
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
Default size for marks.
For
point/circle/square, this represents the pixel area of the marks. Note that this value sets the area of the symbol; the side lengths will increase with the square root of this value.For
bar, this represents the band size of the bar, in pixels.For
text, this represents the font size, in pixels.
Default value:
30for point, circle, square marks; width/height’sstep2for bar marks with discrete dimensions;5for bar marks with continuous dimensions;11for text marks.
- smooth
A boolean flag (default true) indicating if the image should be smoothed when resized. If false, individual pixels should be scaled directly rather than interpolated with smoothing. For SVG rendering, this option may not work in some browsers due to lack of standardization.
- startAngle
The start angle in radians for arc marks. A value of
0indicates up (north), increasing values proceed clockwise.- stroke
Default stroke color. This property has higher precedence than
config.color. Set tonullto remove stroke.Default value: (None)

Default value:
1- strokeWidth
The stroke width, in pixels.
- tension
Depending on the interpolation type, sets the tension parameter (for line and area marks).
- text
Placeholder text if the
textchannel is not specified- theta
For arc marks, the arc length in radians if theta2 is not specified, otherwise the start arc angle. (A value of 0 indicates up or “north”, increasing values proceed clockwise.)
For text marks, polar coordinate angle in radians.
- theta2
The end angle of arc marks in radians. A value of 0 indicates up or “north”, increasing values proceed clockwise.
- thickness
Thickness of the tick mark.
Default value:
1- timeUnitBandPosition
