As a possible solution: have you tried to save the plot to file directly and to open the file afterwards?
yes, I tried to save it first, and after open it, it is still covered by blue.

The matrix is somewhat large, with 1728 rows and 601 columns, but many of them are 0s.

computer info:
Ubuntu 12.04 (precise)
Intel(R) Core(TM) i5-2520M CPU @ 2.50GHz
4G memory

I will try to run it on High performance cluster in our school to see if it has the same problem. Thanks!
