Issue Plotting Array in Imagesc

I am trying to plot an array as an imagesc plot. The array is full of non-zero numbers, but imagesc plots them as zero. I think the issue is with scaling, but I don't know how to fix it. Screenshots attached to show what I mean. How do I scale my imagesc plot so that the numbers in the array are visible appropriately? Tried looking it up on the documentation but couldn't find a clear answer for my problem.

Try taking the log() of the absolute values of the data and see what the result is.

I suspect as most of the data (as seen in the image attached above), is around ~10^10, which is 0.001x10^13, thus the data looks closer to the 0.5x10^13 than to the max value.

If the problem still persists, please attach the data file using the paperclip button.

It might be worth looking at a histogram of the data to see if it would be prudent to pick colorscale limits other than the data extrema.

hello @Rose

it would help if you could share your data (and code if you have one)
