Hi everyone.

I have tried to search for a way to make a learning curve graph with connected lines between mean test results (times) and CI whiskers at three different time points (test 1, 2 & 3).
However, I can not make it work for me.

My data set looks a bit like this:
ID Test 1 Test 2 Test 3
1 4 2 1
2 5 3 2
3 7 6 5
4 2 4 3
5 6 3 4
I want a graph that looks a bit like the picture here - with test times on the Y-axis and the different test time points depicted on the X-axis.

Array

I hope you can help me.

Kind regards,
Sigurd
