Thank you so much Ben,
Now the plot comes correctly after trying your suggestion.
I set cmap.set_under() and cmap.set_over() before calling contourf() and now the plot comes correctly irrespective of cal to the colorbar() function.
Thanks,
Bala

Dear Ben,
you are right, contouf() omits the red and blue values without colorbar.
If i call set_under() and set_over() before calling contourf(), i get an error. This is obvious because i am setting a property of the countourf() object before creating it. I get NameError: name ‘CNF’ is not defined
If i set set_under() and set_over(), after the colorbar(), the colorbar() is shown correctly but contourf() again dose not create the red and blue values. I have also attached my test matrix file with this mail.

Bala, in the code example you gave, you have a cmap object that you pass into contourf. The cmap object that you are accessing after contourf is exactly the same object, so why not just call “cmap.set_over()” before the contourf()?
