This is possible using the YAxis AxisMode
property like this:
RadChart1.PlotArea.YAxis.AxisMode = ChartYAxisMode.Extended;
However this is only available for the axis' maximum value and using the above approach will add additional axis step to the end of the axis. Alternatively you could set the axis AutoScale
to false and manually set your own range using the AddRange
method and set the Min, Max and Step values so they best fit your scenario.
Hope this helps.
All the best,
