Hi,
I have 1440 x 31 matrix 'A' where 1440 is a number of 1minute in one day (24hours x 60), and 31 is a total number of days in July.
Each element in a matrix is a number of vehicles passing specific region,
so A(1,1) is a number of vehicles passing that region in 07-01 00:00~00:01,
A(1,2) is a number of vehicles passing that region in 07-02 00:00~00:01,
and A(2,2) is a number of vehicles passing that region in 07-01 00:01~00:02.
I want to visualize that information with 2d histogram, and also want to visualize peak value with color.. but using histogram2 requires two vectors X,Y
How can I do that with matrix?
+ I want to view the histogram as a tile.

Ohh..If you want it as a tile read about pcolor

I tried imagesc(A). Think it works well :)

Be aware if you use pcolor that it doesn't display all the values as tiles. Watch me display a 4x4 array
m = rand(4,4);
pcolor(m);
Do you see the full m array of 4x4, or only 3x3?

Oh, I want to see the full array.
