Thanks for the interest in RadChart! Yes, a lot of people want to see some features that help with the X-Axis label clutter. We have planned three solutions in mind that will help mitigate the problem:
-LabelStep feature: this will be an integer property which will allow you to display only every N-th label if the axis.
-StairLike labels: this will allow for displaying labels in a stairlike manner using two rows instead of one.
-Label Rotation: this will allow to rotate the axis labels by say 90 degrees and make them vertical to save space.
The bad news is that none of these are implemented yet. We are really pressed in time and will probably have to choose one of those solutions (for Q2). It will be nice to hear from our customers which approach is most useful. Feel free to share your thoughts on this.
