I have a data file that looks a bit like this:

A 0.2  0.5
B 0.65 0.8
C 0.4  0.2

i.e., it contains three columns where the first column contains labels and the other two columns float values. Columns are separated by spaces.

I'd like to plot this in a way that the labels appear as tics on the x-axis while the columns are plotted as two differently colored barcharts on top of each other.

How can I achieve this using Gnuplot?
