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?

Yes, the contourf() function will do that - draw contours. What
exactly were you hoping for? Just the data points? Maybe you want to
use the scatter3() function. Be sure to look at all the options for
it. Or maybe you want the surf() function?

Sounds like pcolor()
