I need to plot the equal width of colorbar like attached image . exampel [0 1 2 4 8 16 32] in all interval width of the colorbar should be same.

I attached my script in which i am plotting rainfall over Indian region, and also attached .mat files of data.

It depends a bit on your release if it is possible to set your scale to logarithmic, but you could also log transform you data and adjust the tick labels.

Can you please elaborate more or if you have some example then it is helpful for me.

I was all set to do it then noticed you didn't attach your data. I can't use .nc format data on some third party web site. Read it in to MATLAB and store it as a .mat file then attach here with the paperclip icon.

files.

There are several tools for that on the file exchange. This for example seems to contain the feature you're looking for: non-uniform-contourf-imagesc-colorbar, This is another very good option: colormap-and-colorbar-utilities.

when I try to run contourfnu command then it's show error,

it's show "Undefined function or variable 'contourfnu'."

can you please guide me how i can use this command.

You need to download the zip file and extract it. You'll need to add the extracted folder to the search path using pathtool.
