以下是我对我的问题的解决方案（我在 2013 年发布）。在寻找答案和解决方案后，我找到了几个代码片段并将它们拼凑在一起，使它们作为一个“团队”工作......省略了一些设置代码以保持列出的代码简短。每个 y 轴的数组是省略的部分之一。
代码片段如下：
class SubFrame_L(wx.Frame): """ SubFrame_L (2169 Lines) 子框架类，用于创建一个框架，其中包括用于绘制图像的图形和画布。
包含以下方法：
BtnPlot - button to invoke select a file to plot
BtnClear - button to clear canvas image
BtnClose - button to close instance of SubFrame_L
BtnWordDoc - button to Export image to Word Document file
BtnPrint - button to Export image to Word Document file & Print
BtnClipboard - button to Export image to Clipboard
DoPlot_SLIK_File - select a file to plot, then transfers to canvas
myLOG_DrawPlot - processes file to plot data arrays.
RePaintL_Canvas - re-draws canvas after a canvas "clear"
Display_SLIK_Parms - displays Parameters read from file
BtnClose_EVT - event handler to clean up and close instance
DblClick_EVT -

画布窗口的有趣特性是它支持双击，这会导致出现一个新的（空白）窗口。部分代码因空间而被省略。
选择包含 4 到 7 列数据的文件。每列都呈现给一个数组[]（每个都有不同的名称）。对插入到数组中的项目的确切数量进行计数。array_of_count[] 将匹配数据数组中的每个条目。并将指示每个 x 轴步长的时间步长（在这种情况下为 0.0167）。已为感兴趣的人上传了一个绘图显示示例。
