New Post: Problems after update (v231 -> v300)

Hello All,

I originally loaded OxyPlot version 231 for my project.
After experiencing difficulties with the context menu, I saw that a number of fixes should remedy my problems - so I installed version 300.
This broke PlotModel.refresh(), but I saw I should replace this with PlotModel.Invalidate().

1) Now the code which tracked mouse movement (from the example) no longer works. If I'm reading my error messages correctly, the event argument attribute "ChangedButton" does not exist any more. Where can I find the changed code (or the changed code example)?

    PlotModel.MouseMove  += (s, e) =>
        {
            if (e.ChangedButton == OxyMouseButton.Left && !double.IsNaN(startx))
            {

2) The earlier sample used references to OxyPlot, OxyPlot.wpf and OxyPlot.xps. The binaries I downloaded included Oxyplot.dll and OxyPlot.wpf.dll but NOT OxyPlot.xps.dll Does OxyPlot.xps (and the dll) still exist or do I need to rebuild or something?

Thanks a lot
