wx.lib. plot how to control legend

Hi,

when using wx.lib.plot, is it possible to control Legend numbers.

Because some time, when we plot a line and add some markers along the line to show the details, and they basicly show the same data. But when we add legend into the plot, all the markers will be added into the legend which is actually not necessary.

I wonder if it is possible to hide certain legend.

Regards!
