Box Plot 2 or more variables

Hello,

I have an issues concerning box plot chart...
I have several bank that give me nominal rate and liquid rate per region and per distributors! I would like to represent it in box plot putting the name of the bank with two box plot, one for the nominal rate and one for the liquid rate!
For the moment I'm just drawing a rectangle from the lower rate to the highest for both nominal and liquid rates. It looks like this but it is not very good and very long to do!
