As our business requirements are very strict we need to be able to set the Graph Scale Maximum and Minimum properties based on our data. This would make our charts much more visually pleasing having the needed empty space above the data. For example, the most often required scenario is setting the Scale.Maximum as a percentage of the already calculated max value by the Telerik Reporting engine. We imagine there would be some kind of object which we can use inside an expression in these properties: = CalculatedMaxValue * (1 + 0.1) Or we can calculate the value ourselves inside a User Function and then use the function in the expression.
