MATLAB: Is the colormap not working as expected

image processing

In the following program cellImage and spineImage, both are being displayed in jet.
One of them should be gray and another should be jet.
But, I see both of them as jet.
%   read three 8-bit images
cellImage = imread('cell.tif'); %Read in 8 bit intensity image of cell
spineImage = imread('spine.tif'); %Read in 8 bit intensity image of spine
onionImage = imread('onion.png'); %Read in 8 bit colour image
subplot(3,1,1); imagesc(cellImage); axis image; %Creates a 3 X 1 mosaic of plots
axis off; colormap(gray); %display first image
subplot(3,1,2); imagesc(spineImage); axis image; %Display second image
axis off; colormap(jet); %Set colourmap to jet (false colour)
subplot(3,1,3); imshow(onionImage); %Display third (colour) image
Output

Up to and including R2014a, colormap was a figure property. With R2014b it started becoming an axes property. You would get the output you observe on R2014a or earlier. (Your earlier questions have not happened to mention which MATLAB you are using)
