How to add one colorbar for three images for different range in matlab

I have a file having temperature data for three different time period

77.1500000000000  31.5000000000000  31.2848032786885  20.8521463414634  22.8482041666667
77.2000000000000  31.5000000000000  31.0782049180328  20.7838699186992  22.7519666666667
77.2500000000000  31.5000000000000  30.8706229508197  20.7152032520325  22.6533300000000
77.3000000000000  31.5000000000000  30.6625491803279  20.6463170731707  22.5531983333333
77.3500000000000  31.5000000000000  30.4542295081967  20.5773252032520  22.4525625000000
77.4000000000000  31.5000000000000  30.2460163934426  20.5084065040650  22.3522041666667
77.4500000000000  31.5000000000000  30.0381885245902  20.4396341463415  22.2529875000000

I want to plot 3,4,5 column with respect to lat lon. So I wrote this code

[lon,lat,temp] = xyz2grid(z(:,1),z(:,2),z(:,3));
pcolor(lon,lat,temp);
shading flat 
h = colorbar;
set(h, 'ylim', [32.450000000000000 31.284803278688520])

Then image is coming. Then the picture is added.

My question is: if I want to make the image for all the columns and put one colorbar in a single frame what change do I have to make?
