我一直在尝试将matplotlib.widget.Button添加到我的matplotlib绘图画布中,该画布已集成在wxPython中,但没有成功。
这是生成画布的代码:
from matplotlib.figure import Figure
from matplotlib.backends.backend_wxagg import FigureCanvasWxAgg as FigureCanvas
import matplotlib.pyplot as plt
import matplotlib
matplotlib.use('WXAgg')
from matplotlib.widgets import Button
import wx
self.figure = Figure()
self.axes = self.figure.add_subplot(111)
self.canvas = FigureCanvas(self, -1, self.figure)
self.sizer = wx.BoxSizer(wx.VERTICAL)
self.sizer.Add(self.canvas, proportion=1, flag=wx.ALL | wx.GROW)
self.SetSizer(self.sizer)
self.Fit()
self.canvas.draw()
plot_object = self.axes.pcolormesh(combo_value.T, cmap='rainbow',
norm=colors.LogNorm(vmin=vmin_value, vmax=vmax_value))
self.canvas.draw()
如何在wxPython中为此matplotlib图的轴添加按钮?我试图遵循这个例子:https://matplotlib.org/examples/widgets/buttons.html,但没有成功,因为你在wxPython的matplotlib中没有使用plt.axes
我尝试过以下操作,实际上确实在画布上添加了一个按钮,但它不是交互式的。
axprev = self.figure.add_axes([0.7, 0.01, 0.1, 0.075])
bprev = Button(axprev, 'Previous')
bprev.on_clicked(self.test())
def test(self):
print('Called')
这就是GUI画布现在的样子: Button that's not interactive
答案 0 :(得分:0)
这似乎是理解使用matplotlib的面向对象方式的问题。大多数pyplot命令直接具有OO等效值作为所使用的相应图形或轴的方法。
以下是将示例转换为面向对象的样式。 (pyplpot
仅用于创建图形并显示窗口,您知道如何在wx中执行此操作。)
import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Button
freqs = np.arange(2, 20, 3)
fig = plt.figure() # use matplotlib.figure.Figure() for embedding
ax = fig.add_subplot(111)
fig.subplots_adjust(bottom=0.2)
t = np.arange(0.0, 1.0, 0.001)
s = np.sin(2*np.pi*freqs[0]*t)
l, = ax.plot(t, s, lw=2)
class Index(object):
ind = 0
def next(self, event):
self.ind += 1
i = self.ind % len(freqs)
ydata = np.sin(2*np.pi*freqs[i]*t)
l.set_ydata(ydata)
fig.canvas.draw_idle()
def prev(self, event):
self.ind -= 1
i = self.ind % len(freqs)
ydata = np.sin(2*np.pi*freqs[i]*t)
l.set_ydata(ydata)
fig.canvas.draw_idle()
callback = Index()
axprev = fig.add_axes([0.7, 0.05, 0.1, 0.075])
axnext = fig.add_axes([0.81, 0.05, 0.1, 0.075])
bnext = Button(axnext, 'Next')
bnext.on_clicked(callback.next)
bprev = Button(axprev, 'Previous')
bprev.on_clicked(callback.prev)
plt.show() # replace with your GUIs start of the mainloop
在函数或方法中使用它时,不要忘记创建Buttons类变量,
self.bnext = Button(axnext, 'Next')
self.bnext.on_clicked(callback.next)
self.bprev = Button(axprev, 'Previous')
self.bprev.on_clicked(callback.prev)
