You can use the VisibleValues
property of the YAxis in order to hide the negative values like shown below:
radChart.PlotArea.YAxis.VisibleValues = Telerik.Charting.Styles.ChartAxisVisibleValues.Positive;
The property has three possible values which are All
. This approach will indeed work without manually specifying the range of your axis.
Hope this helps.
All the best,
the Telerik team
