=======================================
Apply the same scale to multiple tracks
=======================================

A shared scale can be applied to multiple numerical tracks via :class:`~pygv.viewer.GenomeViewer`'s :meth:`~pygv.viewer.GenomeViewer.add_group_autoscale` method.

For the second track, we shrink all value to 1/10 of their original ones
so that we can conveniently check the effect of group label

Let's create the first GV where no group label will be applied

    gv1.add_track(track2)
