Format bar chart colour according text

[andrefraga]

I have the following set of data:

NAME	TYPE	VALUE
A	GA	-0,8
B	GI	0,5
C	PO	0,5
D	GI	-0,8
E	PO	-0,41

<tbody>
</tbody>

I'll create a bar chart with the data in collumns NAME and VALUE. It's a simple bar chart.
But I would like to colour the bars of my chart according to the TYPE collum, for example, GA = Red, GI = Blue and PO = Green.
Could anyone help me?
Thanks!
