ChartDirector 6.2 (.NET Edition)

Floating Box Chart




This example demonstrates creating a multi-color floating box chart.

This chart is composed of 4 box-whisker layers, created using XYChart.addBoxWhiskerLayer. Each layer handles boxes of one color. Only the "box" part of the box-whisker layer is used.
