So the image is what the plot looks like, it does have a 3d appeal when you rotate. I want to filter the plot from 800 to 1000 on the Y axis and 1000 to 1200 on the x axis. After that i want to draw an east-west cross section. Is this possible in matlab? I plotted the mesh plot by right clicking on the data variable "g" in the workspace and choosing mesh plot. That is probably an incorrect way of doing it but can i please get guidance? I am not very experienced and im trying to learn.

sort of like crop the image to along the value i specified just to get a better view of the part that i want to inspect from 800 to 1000 on the Y axis and 1000 to 1200 on the x axis. The main thing is drawing the cross section? Please assist if you can.

Please, at least try the answer I gave below. And again, upload your image if you can't figure it out so we can make a more complete demo for you.

Sure. Looks like you have a 2-D array of gravity data. So just define two points and use improfile() to get a profile between them. Upload your image if you need more help.
p = improfile(grayImage, [x1,x2], [y1,y2]);
plot(p, 'b-', 'LineWidth', 2);
grid on;
