    How should I do a heatplot

    I was asked to plot a heat map over sites in a genome. The in data is tree columns.
    Site1 | site2 | rē
    Where site1 & site2 should point out where in the diagram the point/square/etc is to be. rē is going to tell which color to display.

    If anyone could point out some good link or something to get me in the right direction. I thought I'd have a go at it using MatLab even if I'm more of a java dude... Could it be done in MatLab, in a nice and sorta easy was?

    Edit
    By the way, it's my girlfriend working on a post doc project asking for my help. The indata is stored in excel files, or could be exported into other similar types.

    You use the 3D surface plot tools and rotate the view so you are looking down on the plot.
