Thank you Nick and Maarten

For solution 1 and 2 will the plotted confidence intervals be correct?
I want to try the solution nr 3. Or maybe just edit the graph
afterwards

I will read the Stata Tip

I first used logscale and plotted the 4 lines in the same graph, but
the results was much better when I used 4 separate graphs and not
using logscale.
