canvas = FigureCanvas(self, -1, fig)
canvas.mpl_connect('pick_event',on_pick)
canvas.mpl_connect('motion_notify_event', motion_notify_callback)
SSkey1=wx.StaticText(canvas,-1,"SS",pos=(623,42))
SSkey2=wx.StaticText(canvas,-1,"C-Red",pos=(603,52))
我的代码首先显示文本,但是当我调用canvas.draw()
时,它会更新画布但删除文本。如何才能使文本保留在画布上?
答案 0 :(得分:0)
我假设您的代码中有某个Axes
对象,称之为ax
基本:
ax.text(x, y, 'test')
(doc)
Fancy(有更多选项(tutorial)):
ax.annotate('test', (x, y))
