Re: Can mathematica do a log-log contour plot?



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
