Margins calculated correctly?

[Todd J.]

Hiya,

I have an XY graph and the Y data ranges from 18 - 20. After settign the upperMargin and lowerMargin to 0.1 = 10%, I expected the y-axis max value to be 22 (20 + 20*0.1). However, in reality it appears to be 20.2. Could this indicate a bug in the code?

Thanks,
Todd

PS. I'll be glad to fix this if you point me to the relevant code segment...

Hi Todd,

I've interpreted the margins to be a percentage of the range that is showing on the axis, which in your case is 2 (that is, 20 minus 18).

The code is in the autoAdjustRange() method which is implemented in HorizontalNumberAxis and VerticalNumberAxis() if you want to try out alternatives...

Regards,

DG.
