Hi Feng, there is no built in function for that, you must do it yourself. A quick and dirty way would be to generate tripples with: {Log of x, Log of y, function value at x,y}. Here is an example: dat=Flatten[Table[{Log[x],Log[y],x^2- y^2},{x,1,10,.1},{y,1,10,.1}],1]; ListContourPlot[dat] Note that the axes show the Log's of x and y. But you may draw the ticks yourself. hope this helps, Daniel Feng-Yin Chang wrote: > Hi All, > I have a data array whose indice stand for x,y axes. Is it posiible > to make a log-log contour plot?
