My guess is that you did not fully normalized your distribution. That is the integrated probability of your distribution is not 1.
If you plot your distribution D(x) against a normal distribution N(x) and get a strightline, it mean that your distribution is a constant times the normal distribution, and your distribution is in fact a normal distribution. Check to make sure that Int D(x) =1. People sometimes forget to normalize D after a scale change in x.
ax -> y
D(x) dx = D'(ax) dx -> (D'(y)/a) dy
Sorry I may be totally misunderstood your question. Just want to give you a quick comment since lala is busy.
Have a good day
