matplotlib.lines.VertexSelector — Matplotlib 3.10.5 documentation

class matplotlib.lines.VertexSelector(line)[source]#

Bases: object

Manage the callbacks to maintain a list of selected vertices for Line2D. Derived classes should override the process_selected method to do something with the picks.

Here is an example which highlights the selected verts with red circles:

import numpy as np
import matplotlib.pyplot as plt
import matplotlib.lines as lines

class HighlightSelected(lines.VertexSelector):
    def __init__(self, line, fmt='ro', **kwargs):
        super().__init__(line)
        self.markers, = self.axes.plot([], [], fmt, **kwargs)

    def process_selected(self, ind, xs, ys):
        self.markers.set_data(xs, ys)
        self.canvas.draw()

fig, ax = plt.subplots()
x, y = np.random.rand(2, 30)
line, = ax.plot(x, y, 'bs-', picker=5)

selector = HighlightSelected(line)
plt.show()

Parameters:

lineLine2D

The line must already have been added to an Axes and must have its picker property set.

property canvas#

onpick(event)[source]#

When the line is picked, update the set of selected indices.

process_selected(ind, xs, ys)[source]#

Default "do nothing" implementation of the process_selected method.

Parameters:

indlist of int

The indices of the selected vertices.

xs, ysarray-like

The coordinates of the selected vertices.
