Mathematica Creating a Plot in Two Variables - A Guide

[Safinaz]

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 ?

You have to determine what you are actually doing more detailed.

If you want to have several series in a single plot (different $\kappa_{b\bar{b}}$ in the figure you reference) the answer is simple.
The most elegant solution is given here http://mathematica.stackexchange.com/questions/37127/listplot-multiple-datasets-over-same-x-values

If you want to plot a function taken two parameters you need a 3D ListPlot, https://reference.wolfram.com/language/ref/ListPointPlot3D.html

list1 = Table[{s, f, $\lambda$[s, f]}, {s, -1, 1, 0.1}, {f, -1, 1, 0.1}]

Instead try:

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

A similar example is shown in the documentation for ListPlot
