pyvista.plotting.charts.StackPlot

class StackPlot(chart, x, ys, colors=None, labels=None)

Class representing a 2D stack plot.

Users should typically not directly create new plot instances, but use the dedicated 2D chart’s plotting methods.

Parameters:

chartChart2D

The chart containing this plot.

xarray_like

X coordinates of the points outlining the stacks (areas) to draw.

yssequence[array_like]

Size of the stacks (areas) to draw at the corresponding X coordinates. Each sequence defines the sizes of one stack (area), which are stacked on top of each other.

colorssequence[ColorLike], optional

Color of the stacks (areas) drawn in this plot. Any color parsable by pyvista.Color is allowed.

labelssequence[str], default: []

Label for each stack (area) drawn in this plot, as shown in the chart’s legend.

Examples

Create a stack plot showing the amount of vehicles sold per type.
