Matplotlib 使用wx.SplitterWindow时如何在wxPython中显示光标坐标
我正在尝试做一些类似于本文所示的事情,以绘制一个光标并在状态栏中报告数据坐标。但是,我的代码有点不同,因为我需要使用wx.SplitterWindow来分离按钮和绘图。基本上,在主框架模块中,我创建了状态栏,但绘图是在单独的模块中生成的。请参见下面我的当前代码:Matplotlib 使用wx.SplitterWindow时如何在wxPython中显示光标坐标,matplotlib,wxpython,marker,Matplotlib,Wxpython,Marker,我正在尝试做一些类似于本文所示的事情,以绘制一个光标并在状态栏中报告数据坐标。但是,我的代码有点不同,因为我需要使用wx.SplitterWindow来分离按钮和绘图。基本上,在主框架模块中,我创建了状态栏,但绘图是在单独的模块中生成的。请参见下面我的当前代码: from matplotlib.figure import Figure from matplotlib.backends.backend_wxagg import \ FigureCanvasWxAgg as FigCanva
