From: Anabel on 25 Jul 2010 10:31 Hi! I'm plotting 3D radiation patterns and at the moment I'm being somehow successful. Now I'm struggling with the axis. I'd like to plot the axis as single lines with origin in x=0, y=0, z=0 instead that starting in the botton left point. To show the direction of x, y, z as any antenna simulator does I tried using axis ([0 2 0 2 0 2]) as an example but that crops my figure. Any ideas? I've searched the "help" but it didn't "help" me. Thanks.

From: Anabel on 25 Jul 2010 10:56 Nope. At the moment I have the [0 0 0] in the middle of the plot and that's fine. What I want to do it to plot the 3 axis as lines coming out from that point, from the center of the figure. Maybe it's difficult to explain with words. Something like this: http://www.supernec.com/manuals/snguiorm_files/image017.jpg "Matt J " <mattjacREMOVE(a)THISieee.spam> wrote in message <i2hic5$hec$1(a)fred.mathworks.com>... > "Anabel " <anabel.perezdiaz(a)tut.fi> wrote in message <i2hhrd$f1h$1(a)fred.mathworks.com>... > > > Now I'm struggling with the axis.

Do you think so? Then I must be idiot hehe. I can create arrows and text and stuff but I cannot fix them like 3 coordinate-system axis in the centre of the graph, nor that they move along with the graph when I rotate it :/ help?
