The default colormap has only 64 entries. You can get finer granularity by calling
cmap = parula(256); %calculate parula colormap with 256 entries
colormap(cmap); %activate given colormap
But this might not help, depending how you created the plot. I suspect you might have done something like a scatter() followed by a caxis() ?

Can you attach the .txt file? You may need to zip it to be able to attach it.
