My data is structured such that I have 10 categories that I always want to display on the X axis, regardless of whether there are actually points in the bound collection for each of those 10 categories. Is it possible to define a collection of categories that I want displayed on the X axis prior to binding to an actual data source? Then, once the data source is bound, a line can be drawn between the YValues of the points in the categories that are actually present in the chart?
As a simplified example, say I have categories A, B, C, D, and E. My data has values B=10, D=15, E=12. I want to display a chart where all 5 categories are listed along the X axis with a line drawn between the B->D->E values. Is this even possible in a data bound scenario?

Hello Matt,

You can use RadChart EmptyPointBehavior for displaying the empty categories. If you add your data with null values for your Y-values, RadChart will display the categories, but not the values. When the data comes you can just update your existing points which will update the line accordingly. I have created a small sample project for you that demonstrates this technique.
Hope this helps!
