Made this WIP while I was working on something else.
If this is interesting I can polish it up and test it.
Just let me know

Thanks for this! In principle i really like the idea. Needs a bit more work though. I've added some comments accordingly

This should:

  • return the err instead of panicking.
  • allow the user to specify where to save the file
  • needs to be more configurable in general. e.g. only the first two vars are plotted. What if there are more?

p, err := plot.New()

The var numbers are hardcoded to 0 and 1, but what if there are > 2 vars?

Hi @mish15 and @domenicrosati. I'm going to use this project in my master thesis as a lib. I'M going to need plotting... So since this PR is not completed for a long time, may I continue to work on different PR and contribute to you?. Thanks!

needs to be more configurable in general. e.g. only the first two vars are plotted. What if there are more? for that case. Since we were not able to draw many dimension on graph, should I just show the scatter for variable compared to observed? For instance, assume that observe -> Y and there is two variables on X, X1 and X2. There will be two graph created and statters will be showed on first graph like X1 to Y and on the other graph X2 to Y. For my thesis case, I'm going to have one variable. So things are easy. But for general purpose, I need your comments or advises @mish15 .

@olimpias yeah i guess in general each variable needs to be plotted against Y. Potentially it would also be useful to see X1 against Xn, but that's less important.
