How to erase a (function graphics) plot. [message #79459]

I am building a widget application with a widget_window for displaying function graphics plots. By default, function graphics does not erase the old plot in the same window.

p1 = plot(indgen(10))
p2 = plot( sin(indgen(10),/current)

There is a delete method

p1.delete

but that doesn't delete the axes, which still get jumbled together. There is a close method but that destroys the window, and I'd like to keep reusing the widget_window.

Right now I am erasing the plot by loading a white IMAGE() but I hope there is a better way.

Thanks, --Wayne
