Hi Srikanth,

Thanks for the feedback. I fixed this problem for the 0.6.0 release, but ran out of time to release the code before going on holiday. Unfortunately, I don't have access to the code at the moment, but when I get back I'll post the fix...

Regards,

DG.

The problem occurs becuase the max and min values are the same
and they are both positive. Chart draws nothing for a series of just one
positive value either.

The fix I came up with is this:
for both VerticalNumberAxis and HorizontalNumberAxis modify autoAdjustRange method to include the check below

double upper = vvp.getMaximumVerticalDataValue().doubleValue();
double lower = vvp.getMinimumVerticalDataValue().doubleValue();

/** A. Porebski fixes min=max problem **/
if (upper == lower && lower > 0)
lower = 0.0;
