Problem regarding contour appearance on plot

I am using the following code

v=[200 210 220 230 240 250 275 300 325 350 375 400];
[c,h]=contour(rpm_pq,bmep_pq,bsfc,v);

inside another matlab file the same code has been used I got from my colleague ( he did on Mac matlab) when I run the code on my computer I dont see the colour lines in my code but when I run his code on my same computer then the colour of contour is shown. please assist me in this matter it's urgent
