The feature to restrict the number of displayed labels is already implemented, but it will be available in the Q2 release, which is scheduled for mid September.
What you can do as a work-around until then is to hide some of the x-axis labels so that they are not displayed:
* In this example, for each group of 5 elements, the first will be visible and the next 4 - hidden.

| radChart1.PlotArea.XAxis.Items[i].Visible = (i % 7 == 0); |
