In the above image, you can see that there are 4 curves. I have two techniques (black and red). I test them on two different experimental scenarios. So corresponding to each scenario, I get one red and black curve each. I want to point out that one set of black and red curve belong to one experimental scenario. Hope that clears it. While I am familiar with plotting this curves in pgfplots using the given data, I can't figure how to group them as shown in the image. The plot was generated using matlab.
- How do I group curves in a given pgfplot?
- In your opinion, are there better ways on grouping curves in a plot?
