# How to make this plot?

• Mathematica
Hi all,

I'd like to make a plot like that in [arXiv:1312.1935], FiG. (2), it's a function plotted in a plan of two variables.

I tried :

* ListPlot: for example;

##\lambda##[s_,f_]= s+f;
list1 = Table[{s, f, ##\lambda##[s, f]}, {s, -1, 1, 0.1}, {f, -1, 1, 0.1}];
ListPlot[list1]

But it dosn't work, cause I think ListPlot like that works for one variable.

Also, There is RegionPlot, but it gives a continuous coloured region, while i'd like to have the function as 'dotes' as the green and red in the FIG.

Any help ?

list1 = Table[{s, f, ##\lambda##[s, f]}, {s, -1, 1, 0.1}, {f, -1, 1, 0.1}]
list1 = Table[Style[{s, f},Hue[ ##\lambda##[s, f]], {s, -1, 1, 0.1}, {f, -1, 1, 0.1}]
