Size of the marker's touch area (the area you can touch to select the corresponding chart point). If this size is zero, touch area has the size of marker (that is set with Size property). The default value is 0.0f. Use this property if you want to make touch area more or less then the marker size. The size can be in any unit you want. It is rescaled to pixels with the help of NChartSizeAxis. If no data source is set for size axis, units are interpreted as pixels. See also NChartSizeAxis.
