Unfortunately, it is not possible to alternate the X axis labels this way. As you cannot leave any label out, the LabelStep
property of X axis would not help here -- it can be used to force the chart to display only certain labels like every other or every third label.
So, the only way to show all of them without overlapping is to rotate them. You can use an additional setting,
which will improve the text quality for the rotated labels:
RadChart1.Appearance.TextQuality = Telerik.Charting.Styles.TextQuality.AntiAlias;
Hope this is applicable.
