Might it be possible to allow manual scaling of the Y-axis?
This would allow
- Major Grid at Y=0
- Major Grid of standard intervals (such as the "1,2,5 log" series: .1, .2, .5, 1, 2, 5, 10, 20, 50, 100...)
Also, allow the X-axis to be plotted at Y=0 would help a lot too.
There are a number of situations where the prediction, relative to y=0, is very important.
