multiple colors on format of plot area

[Guest]

How can I change the format of the plot area to multiple colors.

for example I would like to have a Bar Chart with the background plot area
starting @ blue , then Green, then Red. Then have the temperature bars
plot over this area.

thanks

You can do so by bringing a stacked column chart into the mix.

Please see Jon's example below:
