PyPlot relative questions

Erxin · January 15, 2014, 7:28am

As the image show, an OPC IO recording tool is created with
wx.lib.plot.PlotCanvas.
<http://wxpython-users.1045709.n5.nabble.com/file/n5719833/2014-01-15_151009.png>

After the first rough version is created but remain two problems.
1. The point label couldn't be added. I have set enable point label to true
add set a point label function, but it seems that the function is never
called when the mouse pointer hover the data point.

        self.canvas = cvs= wxp.PlotCanvas(pn)
        cvs.SetEnableDrag(True)
        cvs.SetEnableLegend(True)
        cvs.SetEnableZoom(True)
        cvs.SetEnablePointLabel(True)
        cvs.SetPointLabelFunc(self.OnMouseOverCanvasPoint)

The document of SetPointLabelFunc is a few words at doc
<http://wxpython.org/Phoenix/docs/html/lib.plot.PlotCanvas.html?highlight=plot#lib.plot.PlotCanvas.Draw>

SetPointLabelFunc(self, func)
Sets the function with custom code for pointLabel drawing **** more info
needed ***********

Did I misuse something?
2. When enable zoom, if drag a rectangle outside the canvas range make
trigger exception but this is not happen in the PyPlot demo program in wx
2.9.

3. Is it possible to add a content menu with the PlotCanvas ctrl. Do I need
to overwrite the original mouse right down method? Currently it not work
with bind the right click event to the PlotCanvas.

Any suggestions will be appreciated. Thanks in advance!

Please make a runnable, small as possible, sample application that
demonstrates the problem, and let us know the platform and wx version.

OK, I will write a sample application when I have some free time. Thanks
again.
