I have data as shown below:

Long Grass Short Grass Concrete
0.274760448 0.516761782 0.377166667
0.226014478 0.304869311 0.406190102
0.192857171 0.712843314 0.502123457

What I need is one separate column for long, one for short and one for
concrete so I can directly compare them, with error bars and the like.
However, when I graph these, they are separated, with the first line as a set
of 3 columns, the second line as the next set and so on. How do I make only 3
columns to compare them??

Thanks.
