Complex Plotting App

[dwgg]

Hi Han,

With Graph3D, I am already using something similar to what you're suggesting as second option ("Re(f(z)) and Im(f(z)) on the z-axis"). I did minor modification on the Graph3D source code ( namely, disabling function select for 3D contour, then modifying g3D_drawcontour to allow drawing contour plots for multiple functions). What I get is something similar to Conformal map. Here is an example for SIN(X+i*Y):
   

And here is Domain Coloring plot using the same function (entering SIN(X) with my above code):
   

I think what will be good to have is putting these two together, so we get something like below (example from https://gandhiviswanathan.wordpress.com/...functions/):
   

Then we can examine zeros, poles, and conformality all together on the same plot (as well as making the graph look nice).
