Hi Everyone. I want to create Compressor Map . Could you advice me a literature or something that i learn how to create it. Compressor Map is like that. http://www.bing.com/images/search?q=compressor+map&view=detailv2&&&id=D61567EA61B4BF1A32914B7A2F3D3FF257056D97&selectedIndex=0&ccid=QGX3rBFL&simid=608043743320213901&thid=JN.Cklz7CSwlqnK5IUxzxcj8g&ajaxhist=0

That is a contour plot. You can plot a contour plot using contour command.

Thanx for answer. another question that i did not understand. i will use griddata to make Interpolation. This is the documentation of griddata vq = griddata(x,y,z,v,xq,yq,zq) but i did not understand what is v?

In the syntax
vq = griddata(x,y,z,v,xq,yq,zq)
then x and y and z are coordinate vectors or arrays, and v is the array of values for each (x,y,z) combination. xq, yq, zq are the coordinates that you want to extra the values at.
