问题描述
我正在使用matplotlib的 FuncAnimation
来运行动画,以实时显示来自微处理器的数据。我正在使用按钮向处理器发送命令,并且希望在单击按钮后改变按钮的颜色,但在 matplotlib.widgets.button $ c $中找不到任何内容c>实现此目的的文档(尚未)。
I'm running an animation using matplotlib's FuncAnimation
to display data (live) from a microprocessor. I'm using buttons to send commands to the processor and would like the color of the button to change after being clicked, but I can't find anything in the matplotlib.widgets.button
documentation (yet) that achieves this.
class Command:
def motor(self, event):
SERIAL['Serial'].write(' ')
plt.draw()
write = Command()
bmotor = Button(axmotor, 'Motor', color = '0.85', hovercolor = 'g')
bmotor.on_clicked(write.motor) #Change Button Color Here
推荐答案
只需设置 button.color
。
例如
import matplotlib.pyplot as plt
from matplotlib.widgets import Button
import itertools
fig, ax = plt.subplots()
button = Button(ax, 'Click me!')
colors = itertools.cycle(['red', 'green', 'blue'])
def change_color(event):
button.color = next(colors)
# If you want the button's color to change as soon as it's clicked, you'll
# need to set the hovercolor, as well, as the mouse is still over it
button.hovercolor = button.color
fig.canvas.draw()
button.on_clicked(change_color)
plt.show()
