How to refresh text in Matplotlib?
To refresh text in Matplotlib, we can take the following steps −
- Set the figure size and adjust the padding between and around the subplots.
- Create a figure and a set of subplots.
- Add text to the axes.
- Write customized method to update text based on the keys "z" and "c".
- Bind the function action with key_press_event.
- Draw the canvas that contains the figure.
- Animate the figure with texts.
- To display the figure, use show() method.
Example
from matplotlib import pyplot as plt, animation
plt.rcParams["figure.figsize"] = [7.50, 3.50]
plt.rcParams["figure.autolayout"] = True
fig, ax = plt.subplots()
text = ax.text(.5, .5, 'First Text')
def action(event):
if event.key == "z":
text.set_text("zoom")
elif event.key == "c":
text.set_text("cool")
fig.canvas.mpl_connect('key_press_event', action)
fig.canvas.draw()
animation = animation.ArtistAnimation(fig, [(text,)])
plt.show()Output
