[gradsusr] Problem in setting vrange for negative values -scatterplot

[Rashed Mahmood]

Maida

Are you sure that your variables "cpc" and "mod" have negative values?
>From your code it appears (but I am not sure) that the variables are
positive. As you know, the scatter plot won't move towards negative axis
unless one of the variables have negative values. So may be you would like
to confirm variable values first.

Good luck
