This, for me, seems to be the easiest way for ShareZoom to "know" about both plots. Updating the DrawPlot method should hopefully be fairly easy.

I estimate this should take you about 10 minutes, max! Not including
learning about objects, of course. But, once you do, you will understand
why this is so incredible easy to do.

Thank you. :-)

Cheers,
