There needs to be improvement made with the integration of graphs/charts in Reports. The same graph will different results when in a form and a report (lack of consistency). With the need for visual output like charts/graphs growing, its time there is some attention to this in Instant Developer reports. Documentation could be improved, perhaps more samples with code and option settings.
There should be a native chart/graph tool that is a part of Instant Developer that is simple to use and give consistent results in a form and report.
