Thread Subject: adjust colorbar axis in color plot

can anyone tell me how to specify how to specify the scale in the color-bar instead of the default-regular scale.

Ex:
>>caxis([-500,500])

 then it gives -500,0,500

but I want to set axis like this, with different colors:
-500,-300,-150,-50,0,50,150,300,500

can anyone suggest me what should I use, which function...or anything that solves my problem....



Thanks in advance:-)

help colorbar
if it is a countor plot something like this
your_level_lst=[-500,-300,-150,-50,0,50,150,300,500]; [Cctrl,Hctrl]=contourf(Xg,Yg,dispersion,'levellistmode','manual','levellist',your_level_lst,'linestyle','-');
