Currently, RadDiagram uses pixels as the unit of measurement. I have been working on a solution, which requires millimeters as the unit of measurement.
I know I can change RadRuler measurement unit to centimeter (http://www.telerik.com/forums/ruler-that-displays-units-in-inches-mm), but this change only display value on ruler. I need support in the RadDiagram - grid lines in mm, snap to milimeters (not pixels) and page size in mm. How I can add support to milimeters unit?
