I have attached a figure showing the vorticity I have calculated and plot at each time step. I have set the
caxis ([-3500 2500)]
but as you can see, there is much unwanted noise (colour changes) in the graph that make it difficult to see exactly what is going on. Is there any way I can reduce this noise by setting lets say everything between -1000 and 1000 to a single colour? Or is there a better way of doing this?
Thanks for your time

The contour and contourf functions allow you to set the number of contours, and alternately specify the particular values of the contours. See the documentation for Specify Number of Contour Lines for details. Experiment with those and the other options to get the result you want.
