I found 2 problems with this method:

- There is only one line for predicted dose at 5 mg.
- The different doses are 5, 7, and 10 mg but somehow there is a legend for
5,6,7,8,9,10.
- Is there a way to make the line smooth?
- The plots are also getting a little crowded and I was wondering if there a
way to split it into 2 or more pages?

Thanks for your help.
