plotting a 3D data in plane by color
Hi, I like to plot a data set (X,Y,Z) in a smoothly colored X-Y plane which the color in each point is determined with Z values ( a color bar should be displayed as well). I've found "contourf" function near to my need but it draws some contour lines in the figure, too. How can I do this in Matlab? ... 8 Aug 2010 21:06
