plot matrix with image xtics start from 1

Show all headers | View raw

Dear all,

I have a question for plotting a matrix.
For example, there is a matrix stored in file mat.txt and it looks like this:
0 1 2 4
3 2 1 5
2 6 1 6
7 3 1 7
Using command
plot "mat.txt" matrix with image
gives me a 4x4 colored blocks with xtics begin with 0

Using command
splot "mat.txt" matrix using (1+$1):(1+$2):3
gives me a 3x3 colored blocks with xtics begin with 1

My question is: how can I get a 4x4 colored blocks (no interpolation) with xtics begin with 1?

Thanks
