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) comes out.
For each point, I want to give a label. For instance, for (1,2), the label is “0.2”.

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:
where I’m assuming that
points is the 2-element vector of length-2 tuples you posted above.
Annotations vary by plotting package, so again if you want specific advise you’ll need to tell us which package you’re using.
Plots.jl is clever enough to recognize a vector of 2-tuples as coordinates. Doing
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-dimension array. I want to label from y1 to y19, for instance.
using Plots, Printf
x = LinRange(0,1,19)
v = [(rand(0:9),rand(0:9)) for _ in 1:19]
for (i,t) in pairs(v)
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 much again
