I would like to plot multiple sets of x and y data on the same plot with a legend. This is the code I am using right now:

y = Table[f[c1_,inc_], {c1, 0, 3, 0.1}, {inc, {0, 0.2, 0.4, 0.6}}];
x = Table[{c1 + c1 + inc}, {c1, 0, 3,  0.1}, {inc, {0, 0.2, 0.4, 0.6}}];

Each column of y corresponds to a set of y data and each column of x corresponds to a set of x data.

I would like to obtain a plot with multiple curves, ideally with a legend. Ideas?

  • $\begingroup$ May you edit your question and add the definition for f and show the code you have tried. $\endgroup$ – Edmund Apr 9 '16 at 22:20

Here's a start. Since you declined to specify f[ ], I chose one.

f[x_, y_] := x^2 y^2; 
y = Table[{c1 + c1 + inc, f[c1, inc]}, {c1, 0, 3, 0.1}, {inc, {0, 0.2, 0.4, 0.6}}];

  • $\begingroup$ Hi! Thank you very much this helped a lot. My function is a very large mathematica output so I don't think it would have been much help to you. Do you know how I could include a legend in the plot? $\endgroup$ – MathJo Apr 13 '16 at 18:32

  • $\begingroup$ Maybe you are using an older version? $\endgroup$ – bill s Apr 13 '16 at 22:39
  • $\begingroup$ HI! I figured it out. I had to load the package. Your code works well. I noticed for the higher inc, that I have data points for higher x values. For example, in your graph some lines terminate earlier than others. Is there some way I could have them terminate for the same x value? $\endgroup$ – MathJo Apr 14 '16 at 14:29
