For the graph below, I would like to move the 1 on the y-axis down to where 0 is. How do I do that? Or should I switch to two way bar?

This is what my data look like:

var1 var2 var3 var4 var5
1 5.25 6.14 5.62 4
2 5.31 6.18 5.74 4.02
3 5.52 6.3 5.9 4.36
4 5.29 6.21 5.69 3.97
5 5.03 6.1 5.44 3.54
6 5.13 6.12 5.46 3.82


I have this code: graph bar var3 var4 var5, over(var1)

That generated this graph:
