# Select two of three in a triplet list {{x1,y1,z1}, {x2,y2,z2}} [closed]

I have a list of triplets {{x1,y1,z1}, {x2,y2,z2}.....} and would like to plot $$x$$ vs. $$y$$, then $$x$$ vs. $$z$$. ListLinePlot will plot these if they were doublets, but how do I select pairs to plot?

• Look at the documentation page for the Part function. You'll want to use something like data[[All, {1,2}]] for {x,y} and data[[All, {1,3}]] for {x,z}. – user6014 Apr 20 at 18:09
• Thank you -- I did try Part, but I'm still learning the fundamentals of Mathematica (so far, I love it!). I'll use your note as a template and come back with the results, when I give it another shot. Much appreciated! - Andy OK, so I tried it right away -- Yes, it does work. I was close, but it's not second nature yet. Thank you! I will return the favor to someone else..... – alaz Apr 20 at 21:11

Contrived data producing a list of 10 triples of the form {{1, y1, z1}, {2, y2, z2}, ...}.

SeedRandom[1]; data = Table[{i, Sequence @@ RandomReal[1., 2]}, {i, 10}];


Now we plot x & y and x & z.

ListLinePlot[{data[[All, ;; 2]], data[[All, ;; 3 ;; 2]]}]


or

ListLinePlot[{data[[All, {1, 2}]], data[[All, {1, 3}]]}]


Both display

Note: Look up Part and Span in the docs,
