This point represents the Cartesian coordinate position along x-axis and y-axis. You can provide the data to the chart control by using data provider property. You will use xField, yField and radius property for series.  You can use more than one series in it. You can change the icon style by busing itrmRenderer property.
There are some default item renderer classes:
1. BoxItemRenderer
