ChartDirector 6.2 (.NET Edition)

Bubble XY Scaling




This example demonstrates a bubble chart with independent x and y bubble sizes and non-circular bubbles.

In ChartDirector, a bubble chart in general is a scatter layer with the symbol sizes controlled by some other data series.

ChartDirector supports using arbitrary symbols as bubbles. Thus bubble shape is not limited to circle but can be any shapes.

Furthermore, ChartDirector supports independent x and y sizes for bubbles. This is useful for creating charts in which the bubbles reflect some features of the data points, such as its confidence zone, x and y errors, x and y standard deviations, etc.
