prepareXYModel

public static org.zkoss.zul.XYModel prepareXYModel(SChartData chartData)

Scatter chart that uses XYModel has following characteristics: 1. It always has two value axes to show one set of numerical data along a horizontal (value) axis and another set of numerical values along a vertical (value) axis. 2. If X axis value is not numeric, we convert them to a default series with index, e.g. 1, 2, 3, 4...etc like Excel does.

Returns:

data model for scatter chart

prepareXYZModel

public static org.zkoss.zul.XYZModel prepareXYZModel(SChartData chartData)

The bubble chart that use XYZModel has similar characteristics as scatter chart. Its X axis always shows numerical data. If X axis value is not numeric, we convert them to a default series with index, e.g. 1, 2, 3, 4...etc like Excel does.
