Here are the steps that I would use:
1. Define a color bar with blue colors in the indices 0-127, where 0 is dark
blue and 127 is white. Then you put the red colors in indices 127-255, where
127 is white and 255 is the dark red.
2. Then use bytscl to scale your range: xbyte=bytscl(x,min=-300,max=300)
3. Use TV to display the array.
