matplotlib multicursor

Showing a cursor on multiple plots simultaneously.
This example generates three axes split over two different figures. On
hovering the cursor over data in one subplot, the values of that datapoint are
shown in all axes.

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import MultiCursor

t = np.arange(0.0, 2.0, 0.01)
s1 = np.sin(2*np.pi*t)
s2 = np.sin(3*np.pi*t)
s3 = np.sin(4*np.pi*t)

fig, (ax1, ax2) = plt.subplots(2, sharex=True)
ax1.plot(t, s1)
ax2.plot(t, s2)
fig, ax3 = plt.subplots()
ax3.plot(t, s3)

multi = MultiCursor(None, (ax1, ax2, ax3), color='r', lw=1)
plt.show()

polygon selector

import matplotlib.pyplot as plt from matplotlib.widgets import PolygonSelector # To create the polygon programmatically fig, ax = plt.subplots() fig.show() selector = PolygonSelector(ax, lambda *args: None)

matplotlib radio buttons

Using radio buttons to choose properties of your plot. Radio buttons let you choose between multiple options in a visualization. In this case, the buttons let the user choose one of the three different sine waves to be shown in the plot.

matplotlib Rectangle and ellipse selectors

Click somewhere, move the mouse, and release the mouse button. `.RectangleSelector` and `.EllipseSelector` draw a rectangle or an ellipse from the initial click position to the current mouse position (within the same axes) until the button is released

matplotlib slider

In this example, sliders are used to control the frequency and amplitude of a sine wave. See :doc:`/gallery/widgets/slider_snap_demo` for an example of having
