I'm trying to plot a couple of vectors (using arrows) and their projections on the x- and y- axes (using lines):
a1=arrow((0,0),(3,1),rgbcolor=(0,1,1)) a2=arrow((0,0),(-3.5,2.5),rgbcolor=(0,0,1)) l1=line([(0,0),(-3.5,0)],rgbcolor=(1,0,0)) l2=line([(0,0),(0,2.5)],rgbcolor=(0,1,0)) p=point((3,1),rgbcolor=(0,0,1),pointsize=30) show(a1+a2+l1+l2+p) The arrows went fine but the lines didn't show up. Curiously: a) if I use arrows instead, they do show up. b) if I plot a line somewhere else, like line([(0,-1), (-3.5,0)],rgbcolor=(1,0,0)), it works!!!! I'm running Sage Version 3.2, Release Date: 2008-11-20 in case it helps.
