I think this is an extremely simple question, but I just can’t really understand how the plot function reads my inputs. For instance, I want to plot two points with scatter: (1,2) and (2,3) in a two-dimension vector space. Each point is an outcome of my function. If I put 0.2 to the function, (1,2…

One way: using Plots, Printf x = LinRange(0,1,19) v = [(rand(0:9),rand(0:9)) for _ in 1:19] plot(legend=:outerright) for (i,t) in pairs(v) scatter!(t, label=@sprintf("%.2f",x[i])) end Plots.current()

Which plotting library are you using? For the most part, points to plot are provided as a vector of x coordinates and a vector of y coordinates. In your case you could do this as: plot(first.(points), last.(points) where I’m assuming that points is the 2-element vector of length-2 tuples you poste…

Plots.jl is clever enough to recognize a vector of 2-tuples as coordinates. Doing scatter([(1,2),(3,4)]) produces [image]

Thank you very much for the replies. I’m using Plots.ji. I’ve tried with the above one, but it returns the following. This is only half of what I want. Somehow, the scatter function is perceiving my input only as y1, but what I’m putting in is a 19-element vector of which each row is a two-dimen…

I didn’t expect that the problem will be this complicated. In the end, I could manage to get the following plot. I really appreciate your suggestion. If I may ask one more thing, I was wondering if there is any way that I can put each label right above each point in the diagram. Thank you very m…
