This has been posted to excel.charting.

I am trying to plot this formula: r = a + b Cos(KQ), on a radar chart. Everything works just fine except that when I change the values of the b variable, Excel will not plot the chart correctly. However, if I manually change the major gridlines, MimimumScale = 0, it plots correctly. The macro recorder sets minimum and maximum to auto (see below). I need to set minimum to 0 (zero). The subroutine stops at ..MinimumScaleIsAuto = True and MinimumScale = 0. The error message is “unable to set MinimumScale Property of Axis class.” Can someone tell me how to overcome this? I appreciate your help.



Thanks.
