pyvista.ChartMPL

class ChartMPL(figure=None, size=(1, 1), loc=(0, 0), redraw_on_render: bool = True)

Create new chart from an existing matplotlib figure.

Parameters:

figurematplotlib.figure.Figure, optional

The matplotlib figure to draw. If no figure is provided ( None ), a new figure is created.

sizesequence[float], default: (1, 1)

Size of the chart in normalized coordinates. A size of (0, 0) is invisible, a size of (1, 1) occupies the whole renderer’s width and height.

locsequence[float], default: (0, 0)

Location of the chart (its bottom left corner) in normalized coordinates. A location of (0, 0) corresponds to the renderer’s bottom left corner, a location of (1, 1) corresponds to the renderer’s top right corner.

redraw_on_renderbool, default: True

Flag indicating whether the chart should be redrawn when the plotter is rendered. For static charts, setting this to False can improve performance.

Examples

Plot streamlines of a vector field with varying colors (based on this example).

>>> import pyvista as pv
>>> import numpy as np
>>> import matplotlib.pyplot as plt

>>> w = 3
>>> Y, X = np.mgrid[-w:w:100j, -w:w:100j]
>>> U = -1 - X**2 + Y
>>> V = 1 + X - Y**2
>>> speed = np.sqrt(U**2 + V**2)

>>> f, ax = plt.subplots()
>>> strm = ax.streamplot(X, Y, U, V, color=U, linewidth=2, cmap='autumn')
>>> _ = f.colorbar(strm.lines)
>>> _ = ax.set_title('Streamplot with varying Color')
>>> plt.tight_layout()

>>> chart = pv.ChartMPL(f)
>>> chart.show()
