Assigning a color to each variable

Hi, I was wondering if there was a way of automatically assigning a color to each bar when doing a bar plot (, something similar to color=:variable in Gadfly.
My data looks like this:

Var1 Var2 Var3
1 0.000224135 APR
1 7.60581e-6 NAPR
1 0.0025156 SF
2 4.79794e-5 APR
2 0.00057933 NAPR
2 0.0051411 SF

This is how I would do it with Gadfly:
figure = Gadfly.plot(

But I need to use Plots.
Thanks a lot!
