Reporting module line graph

you can change the min,max axis range on a line graph in the reporting module and the grid appears to be filled in using a calculation based on the that range. is there a way to force the number of grid lines or add additional grid lines in between the calculated grid lines (similar to the easy chart)?

Unfortunately the gridlines in the Chart in the report component are all calculated behind the scenes based on the min/max you use and cannot be otherwise changed.
