Bubble Chart
A bubble chart draws bubbles of different sizes (diameters) in 2D space. |
|
The bubble chart is based on XY Plot and XY Renderer. It inherits all their properties.
This is what bubble chart looks like:
Dataset
The bubble chart supports Custom Data model only.
It has the following Source Data Bindings:
Binding | Expected Value Type | Description |
Series | String | Textual name of the data series. |
X | Number | X (domain) coordinate of the bubble center. |
Y | Number | Y (range) coordinate of the bubble center. |
Z | Number | Z-value, that may be bubble diameter, its length along the X-axis or its length along the Y-axis. These depends on the Scale Type property. |
Common Properties
Width, Height, Bindings, Visible, Opaque, Background, Border
All Data-related properties.
All properties of a XY Plot.
All properties of a XY Renderer.
Custom Properties
Scale Type
Method used to determine the size of the bubbles drawn by this renderer:
- Scale On Both Axes: bubbles are drawn as ellipses where the width and height of the ellipse is determined by the z-value scaled against both axes;
- Scale On Domain Axis: bubbles are drawn as circles where the diameter of the circle is determined by the z-value scaled against the domain axis;
- Scale On Range Axis: bubbles are drawn as circles where the diameter of the circle is determined by the z-value scaled against the range axis.
Property name: scaleType
Property type: Integer
