You didn't give us any information as to what the function was or in what sense the plot 'didn't work well'. With a complicated numerical function f[x,y,z] it may be very difficult to obtain a picture because it might be quite oddly 'shaped' and the Mathematica plotting routine might miss important details. In a 3D contour plot it might be difficult to pick suitable contours or a suitable plot domain and range. So you may have to use simpler graphics or even tables to 'explore' the function before you can obtain a good graphical representation. You could, for example take slices of the function by fixing z and using a 2-dimensional contour plot or Plot3D. Depending on the nature of the function, it may take a number of representations to obtain an adequate understanding of its behavior. Simply trying to do a quick 'set-piece' plot of a complicated function will often fail. -- David Park djmpark at comcast.net http://home.comcast.net/~djmpark/ "shingo" <shingo.yoshimura at gmail.com> wrote in message news:g8rfei$f9h$1 at smc.vnet.net... > Hi guys.
