How can I make a filled contour plot with data that has x,y coordinates and values corresponding to each point?

Before today, I have never touched Matlab, but I've been pretty happy to see that it's similar to the R language with a few syntax differences. Anyway, I have a data file that contains weather radar data in cartesian coordinates with corresponding values to the point that is arraged [x.coord,y.coord,value] and it looks like this-

    0.0013    0.0750  -49.3675
    0.0026    0.0750  -48.3390
    0.0039    0.0749  -51.4245
    0.0052    0.0748  -51.9387
    0.0065    0.0747 -513.7308
    0.0078    0.0746  -52.4530
    0.0091    0.0744  -51.9387
    0.0104    0.0743  -48.8533
    0.0117    0.0741  -49.3675
    0.0130    0.0739  -50.9103

I want to create a contour plot of the data with each value at the intersection of the two points (ex (0.0013,0.0750) would have value -49.3675) and then contour and fill the plot. I saw that contourf could potentially be used, but I have been having problems getting it to work. I think I typed coherently, but it's possible that I didn't. If you need clarification, let me know. Any help would be greatly appreciated. Thanks in advance!

We were just talking about that case on this thread .
