Zone Struct

Structure to define a shaded region which appears as part of the chart background. Zones may be used on any conventional 2-dimensional chart (see the Gantt tutorials) or on Dial charts to mark out significant areas on the scale. Each Zone has a start and stop value, a color and an optional fillstyle.

For xy-plots (scatterplots or bubblecharts) you may define a matching array of x-zones and y-zones to mark out arbitrary rectangular areas on the chart by using ZoneStyles.Intersect. These are shaded at the intersection of the zone pairs rather than spanning the axis range.
