.... I just tried it set view map... it worked... Thank you.

Also I want to know does gnuplot automatically calculates the 1,2,3.. sigma ranges ?
I have three columns.. x,y,z. For contour plot I am using the above commands with -
 "$set cntrparam levels discrete 2.3,6.2,11.8"
 which are 1,2 and 3 sigma levels respectively for 2 parameter correlation.
But in my z column these sigma values are not present still I am getting a plot.. I am confused that what does it mean ? 
What I know is- for particular z values of confidence levels contours are drawn for x and y for corresponding z values set by the user.. Am I correct ?
