I have a Crystal Report that contains a line chart. It works good but I want to be able to dynamically change the Data, for example I want to chage the option "On Change of" that at this moment is date for a differente field. Also I want to be able to change the "Show value(s)" summary operation from sum to avg from my asp.net page using C#. I wan to know if this is possible passing parameters and some kind of formulas but I haven't found anything on the Internet so far. Any help will be appreciate it.
