Stacking graphsets

As explained here, a graphset is an object used to group series and plot them against different scales. JetChart uses the full extension of the vertical axis to arrange scales. If series are grouped into more than one graphset, each graphset scale is, by default, arranged along the left vertical axis, in which case the scales labels overlap each other. If only two scales are displayed, a workaround is to move one of the scales to the right vertical axis. However, if more than two scales are displayed, the only solution is to stack the graphsets vertically, setting the start and end scale points in terms of fractions of the full vertical y axis extension.

Scale edges can be manually set or automatically calculated. The following example displays three series grouped into three graphsets. The scales edges are manually adjusted to prevent graphsets from overlapping.
