I am changing the colorbar scale using the caxis command --- caxis([1 2]) --- (for 3 polar plots) but in all the cases the colors in the plot are disappearing.
I don't know why this is happening. Please help.

>> contourf(PhC) >> colorbar >> caxis([1 5])
when I do this the colors in the graph goes away... PhC is a file from which I am importing the values

Please read the documentation
doc caxis
From the description of your problem I would guess that the values in PhC are either all inferior to the inferior limit in caxis or larger than the superior limit. That would cause your plot to have only one color.
