You can easily obtain the current number of labels generated on each axis through the radChart1.PlotArea.XAxis.Items.Count
properties. That number, however, depends on the LabelStep
property as only the required number of labels are generated.
To aquire the correct number of data points, you just need to retrieve it from this.radChart1.Series.Items.Count
. This will solve the problem for X axis, but I am not sure what you need as information on the Y axis. Usually, the Y axis automatically scales itself, searching for the optimum number of labels and optimum range to correctly represent the given range.
