I have some data which I would like to plot in matlab(surfacem matlab function). So here I have latitude, longitude & Ch4 in my data set the Ch4 values are very small, e.g maximum is 5.20*10^-8, 1.28*10^-08 and minimum ones 4.43*10^22, 1.78*10^22. So what I have done that I took log10 of these values. But still when I finish my plotting the output does not look good.
So how to fix this kind of problem.

Min and Max values are reversely stated. "does not look good" is in the eye of the beholder.

You cannot upload images in this forum, but you can link to images. For a summary list of sites, see http://www.mathworks.com/matlabcentral/answers/7924-where-can-i-upload-images-and-files-for-use-on-matlab-answers

You can probably try scaling the values by multiplying it with a constant. No you would end up having the same kind of behavior just that you would have a more magnified version.
