A matrix chart shows relationships between two or more variables in a data set in grid format. The matrix chart is formed through at least two variables, for the X- and Y-categories. If there is a third or fourth variable, colour or other another dimension can be added to the matrix to represent it.
The <Matrix2DChart> element tag is used to create a matrix chart in KoolChart, and the series element tag for the matrix chart is <Matrix2DSeries>.
This sample chart is to show how to create a "fill" type matrix chart.
... <Matrix2DChart type="fill" ... > ... <series> <Matrix2DSeries xField="Data1_x" yField="Data1_y" zField="Data1" ... /> <Matrix2DSeries xField="Data2_x" yField="Data2_y" zField="Data2" ... /> <Matrix2DSeries xField="Data3_x" yField="Data3_y" zField="Data3" ... /> </series> ... </Matrix2DChart> ...
|type||The type attribute determines the drawing or fill type of the cell in the grid. The valid values are "renderer", "fill", "image" and "plot".|
|xField||The xField attribute determines the field name of the horizontal axis ( horizontalAxis ).|
|yField||The yField attribute determines the field name of the vertical axis ( verticalAxis ).|
|zField||The zField attribute determines the field name of the data represented in the cell of the grid.|
