pyvista.plotting.charts.BarPlot

class BarPlot(chart, x, y, color=None, orientation='V', label=None)

Class representing a 2D bar 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

Positions (along the x-axis for a vertical orientation, along the y-axis for a horizontal orientation) of the bars to draw.

yarray_like

Size of the bars to draw. Multiple bars can be stacked by passing a sequence of sequences.

colorColorLike, default: “b”

Color of the bars drawn in this plot. Any color parsable by pyvista.Color is allowed.

orientationstr, default: “V”

Orientation of the bars drawn in this plot. Either "H" for an horizontal orientation or "V" for a vertical orientation.

labelstr, default: “”

Label of this plot, as shown in the chart’s legend.

Examples

Create a stacked bar chart showing the average time spent on activities throughout the week.

>>> import pyvista as pv
>>> import numpy as np
>>> x = np.arange(1, 8)
>>> y_s = [7, 8, 7.5, 8, 7.5, 9, 10]
>>> y_h = [2, 3, 2, 2.5, 1.5, 4, 6.5]
>>> y_w = [8, 8, 7, 8, 7, 0, 0]
>>> y_r = [5, 2.5, 4.5, 3.5, 6, 9, 6.5]
>>> y_t = [2, 2.5, 3, 2, 2, 2, 1]
>>> labels = ["Sleep", "Household", "Work", "Relax", "Transport"]
>>> chart = pv.Chart2D()
>>> _ = chart.bar(x, [y_s, y_h, y_w, y_r, y_t], label=labels)
>>> chart.x_axis.tick_locations = x
>>> chart.x_axis.tick_labels = ["Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun"]
>>> chart.x_label = "Day of week"
>>> chart.y_label = "Average time spent"
>>> chart.grid = False  # Disable the grid lines
>>> chart.show()
