使用单选按钮根据字典的项目更改图表的情节

changing the plot of a graph based on the items of a dictionary using radiobuttons

我有一本包含许多项目的字典。我想创建单个图形,其中单选按钮的数量等于字典中的项目数。单选按钮选项将是字典的键,每次您 select 编辑不同的单选按钮时,相关值都会相应地绘制出来。例如:

from matplotlib.widgets import Slider, Button, RadioButtons

data = {'A' : [1,2,4,6,7,8,10],'B' : [1,2,4,6,4,3,7], 'C' : [3,2,1,6,2,3,4]}

axcolor = 'lightgoldenrodyellow'
rax = plt.axes([0.025, 0.5, 0.15, 0.15], facecolor=axcolor)
radio = RadioButtons(rax, data.keys(), active=0)

def chooseGraph(graph):
    [plt.plot(data[names]) for names in data.keys()]
radio.on_clicked(chooseGraph)

plt.show()

当我执行这段代码时,我得到了单选按钮,但没有图表。当我 select 一个按钮时,所有 3 个数据集都绘制在单选按钮的顶部,更改按钮只会更改颜色。

提前感谢您的帮助!

您需要创建一个轴来绘制数据,否则它会选择当前活动的轴,即带有单选按钮的轴。

import matplotlib.pyplot as plt
from matplotlib.widgets import RadioButtons

data = {'A' : [1,2,4,6,7,8,10],'B' : [1,2,4,6,4,3,7], 'C' : [3,2,1,6,2,3,4]}

fig, ax = plt.subplots()
ax.plot(data["A"])

rax = fig.add_axes([0.025, 0.5, 0.15, 0.15])
radio = RadioButtons(rax, sorted(data.keys()), active=0)

def chooseGraph(graph):
    ax.clear()
    ax.plot(data[graph])
    fig.canvas.draw_idle()

radio.on_clicked(chooseGraph)

plt.show()
