[英]Displaying Radio buttons horizontally in matplotlib
我正在使用matplotlib.widgets
在我的小部件中創建單選按鈕,即將出現的按鈕垂直堆疊,我希望它們水平堆疊。
MVCE:
import matplotlib.pyplot as plt
from matplotlib.widgets import RadioButtons
plt.subplots_adjust(left=0.2)
rax = plt.axes([0.5,0.05,0.1,0.1])
radio = RadioButtons(rax ,['1','2','3'], active=0, activecolor='blue' )
plt.show()
我想知道有沒有辦法水平堆疊這些單選按鈕。
當前正在嘗試向PR#13374中的 RadioButtons
引入orientation
參數。 尚未完成。
正如我在此PR中評論的那樣,另一種選擇是對按鈕使用散點圖。 下面顯示了我如何想象此實現。 與常規按鈕相比,有兩個主要增強功能:
這是通過在內部創建圖例來實現的,該圖例具有所有可用的必需選項。 “ Legend
任何有效參數也可以用於“按鈕”。

Add radio buttons to an `~.axes.Axes`.
Parameters
----------
ax : `~matplotlib.axes.Axes`
The axes to add the buttons to.
labels : list of str
The button labels.
active : int
The index of the initially selected button.
activecolor : color
The color of the selected button.
size : float
Size of the radio buttons
orientation : str
The orientation of the buttons: 'vertical' (default), or 'horizontal'.
Further parameters are passed on to `Legend`.

AxesWidget.__init__(self, ax)
self.activecolor = activecolor
axcolor = ax.get_facecolor()
self.value_selected = None
ax.set_xticks([])
ax.set_yticks([])
ax.set_navigate(False)
circles = []

def _clicked(self, event):
if (self.ignore(event) or event.mouseevent.button != 1 or
event.mouseevent.inaxes != self.ax):
return
if event.artist in self.circles:
self.set_active(self.circles.index(event.artist))
用作
plt.subplots_adjust(left=0.2)
rax = plt.axes([0.5,0.05,0.4,0.07])
radio = MyRadioButtons(rax ,['1','2','3'], active=0, activecolor='crimson',
orientation="horizontal")
plt.show()
要么
rax = plt.axes([0.2,0.5,0.25,0.1])
radio = MyRadioButtons(rax ,["AA", "BB", "CC", "DD"], ncol=2)
由於 stackexchange 不希望將此作為編輯,因此這是來自 @ImportanceOfBeingErnest 的上述答案的更新版本,適用於最新的 matplotlib 版本(例如 >= v3.3)
