Dear Friends: This is a quite primitive problem (actually, 2 related problems). I have a set of points, which I want to put into a triangle and then draw some lines. The triangle I build in the following way= triangulo=Line[{{0,0},{0.5,0.5},{1,0},{0,0}}]; The I christen my set of points: milista={{0.589286,0.330357},{0.553571,0.4375},{0.552632,0.429825},{0.508772,0.0526316},{0.578947,0.342105},{0.57,0.26},{0.57,0.29},{0.48,0.25}} I make a graphic: miejemplito=ListPlot[milista, PlotStyle®{PointSize[0.03]} ] Then I put them into the triangle: Show[Graphics[triangulo], miejemplito, PlotRange®All] All this works fine. I start to draw the lines: jo1=Line[{{0.5,0},{0.5,0.5}}]; jo2=Line[{{0.4,0.4},{0.8,0}}]; jo3=Line[{{0.4,0.4},{0.8,0}}]; jo4=Line[{{0.1,0.1},{0.2,0}}]; and then Show[Graphics[triangulo],Graphics[jo1],Graphics[jo2],Graphics[jo3], Graphics[jo4], miejemplito, PlotRange®All] So far, so good. However, when I add jo5=Line[{{0.8,0},{0.9,01}}]; and then give the directive Show[Graphics[triangulo],Graphics[jo1],Graphics[jo2],Graphics[jo3], Graphics[jo4],Graphics[jo5], miejemplito, PlotRange®All], I get an extremely awkward and badly drawn graphic, and the last line (jo5) escapes the triangle. a. How can I correct the problem? b. How can I put labels to each point (and eventually colour them differently)? Thanks in advance Fg
