Several range plots in one graph

[Mathias Rechsteiner]

Hello Stata users

I am quite new in Stata and try to create a range plot. My data set has 9 variables and 4 records. What I d like to have is a graph with 4 range plots (var1 - var2 / var3 - var4 / var5 - var6 / var7 -var8) for every year.

var1 var2 var3 var4 var5 var6 var7 var8 year
31.76 36.24 37.96 41.46 32.75 37.12 38.45 42.04 9
42.07 45.65 48.09 51.38 42.71 46.83 49.35 52.06 11
45.05 50.11 52.71 55.15 46.72 51.17 53.26 56 13
50.75 51.59 57.8 59.74 51.49 60.25 53.71 60.8 15

I typed the following command: twoway (rcapsym var1 var2 year) (rcapsym var3 var4 year) (rcapsym var5 var6 year) (rcapsym var7 var8 year)

The output graph looks almost fine, but I would like to have the range plots in parallel not in the same line. More precisely as the values at year 9 are all between 31 and 42, the range plots overlap in the graph. My preferred figure would group for every age the 4 range plots, so that there is no overlapping.

Thank you very much for your help!

Just add a small interval to year across groups.

Thank you very much Andrew for your precious help! It makes my day. Once you see the solutions, it is so obvious how to solve :-)
