JRBubblePlot (JasperReports Library Javaflow 6.21.2 API)

All Superinterfaces:

Cloneable, JRChartPlot, JRCloneable, JRXAxisFormat, JRYAxisFormat

All Known Implementing Classes:

```
public interface JRBubblePlot
extends JRChartPlot, JRXAxisFormat, JRYAxisFormat
```
Only Bubble charts use this type of plot. Like all other two-axis plots, it lets users control the labels displayed for each axis.
The plot draws an ellipse for each item present in the dataset for a given series. Usually this is a circle whose radius is specified by the Z value in that chart item. However, the plot needs to know whether the Z value is proportional to its corresponding X value or to its corresponding Y value in order to calculate the actual size of the bubble.
The type of bubble scaling is specified by the scaleType attribute that the plot exposes:
- Range axis scaling: The bubble is a circle with the radius proportional to the Y value for each item (scaleType="RangeAxis").
- Domain axis scaling: The bubble is a circle with the radius proportional to the X value for each item (scaleType="DomainAxis").
- Scaling on both axes: The bubble is an ellipse with the height proportional to the Y value and the width proportional to the X value for each item (scaleType="BothAxes").
By default, bubbles scale on the range axis.
