SymbolAnnotationRenderer<D> class

Series renderer which draws a row of symbols for each series below the drawArea but above the bottom axis.

This renderer can draw point annotations and range annotations. Point annotations are drawn at the location of the domain along the chart's domain axis, in the row for its series. Range annotations are drawn as a range shape between the domainLowerBound and domainUpperBound positions along the chart's domain axis. Point annotations are drawn on top of range annotations.

Limitations: Does not handle horizontal bars.
