Hi all. I'have problem..
I have mat file with 4 columns (long, lat, time, and data).. ignored about the time, so I'm focused only long, lat, and time. The question is how I'm making contour (pcolor with the 1st,2nd, and 4th use only), because the column for long it doesn't look nice grid.
Tks for your help..

What data it is? Using whole data to plot contours would be messy.....Better to involve time.

it is data satellite altimetry. Sorry, I'm correct my first question I'm focused only long, lat, and data (not time). So my aim is drawing like this attach.. is it possible?
