Set Matlab's Contour graph x-axis scale?

I am trying to graph a contour graph with a two dimentional matrix, v. v contains velocity data, y-index represents depth, x-index is mapped to a 1d-vector containing latitude info, lat.

when I graph contour(v), the x-axis is index, but I wish to show the latitude (also scale accordingly), I tried contour(lat,v) but it just shows me a blank graph, how should I graph it?

Without having an example dataset, it's hard to say for sure... but I suspect that what you need to do is use the contour(X,Y,Z) form of contour. If you want to specify one axis, you need to specify both. In your case, it would be:

contour(lat,depth,v)

If you're happy using the y-index rather than an actual depth vector, you can do

contour(lat,1:size(v,2),v)
