I have this type of data:

Data = [1:1:9; 1 2 3 4 5 6 7 8 9; 1 2 3 4 5 6 7 8 9 ;1 2 3 4 5 6 7 8 9;1 2 3 4 5 6 7 8 9];

Where the first entry is the zone of interest (9 zones total) and the remaining 4 array entries are how long something stayed in the zone (just arbitrary now for this question.

I want to plot how long each thing is in each zone on a picture of a map as a 3d "heatmap" style plot. The map is divided into a 3x3 grid like so:

2 3 
5 6
8 9

How do I plot this? I have tried the contour and surf functions but I am not sure how I would map them to the grid. I would like to overlay the graph on a map picture as my final step but just getting the graph up and running would be great!

I think something must be missing--What do you mean by "the remaining 3 array entries"?

hi chad,you mean the other 4 rows of data? The first entry in Data = [X;A;B;C;D], X is the zones in the grid, the other 4 entries A-D is the actual data I want to histogram/heatmap plot. So the A(1) correlates to X(1), or the first value in A is the value for zone 1 in the plot.
