I have attached the picture of contour I have obtained via contourf and extremely lengthy code. Now i want to remove or make transparent the middle section of contour with temperatures having 80 degrees. Now in order words the temperature inside the core is already known and I dont want to show it on contour please help anybody.

The inside core (80 degrees shouldnt be available) SOLID WORKS Results

MATLAB Results

NOW I WANT BOTH TO LOOK SIMILAR SO PLZZ HELP ME GET RID OF MATLAB INSIDE CORE TEMPERATURE REPRESENTATION. I EVEN HAVE ALL THE COORDINATES OR NODES OR ADDRESSES OF THESE INSIDE CORE VALUES OF 80 DEGREES

The example in this answer is similar. Therein, the lowest contour level is made transparent. If you dont want the other levels to be semitransparent, you can omit that part.

Alternatively, you could either mask the region with NaN as dpb suggests, or you could possibly just overlay a patch object if actual transparency is unnecessary. It depends whether it's better to define the region strictly geometrically or simply by using the data level.
