celarson	Posted - 03/03/2003 : 5:00:32 PM This has got to be easy but I can't figure it out. I have a simple x,y plot and want a couple boundary lines included. I see how to plot a line, for example, at y=12 using the graph->add function graph dialog. Now how do I get origin to plot me a line at say, x=10?

Mike Buess	Posted - 08/26/2003 : 10:09:55 AM Hi Jiang, This will draw a line from (X0,0) to (X0,sin(X0))... draw -l {X0,0,X0,sin(X0)}; Mike Buess Origin WebRing Member
jlm	Posted - 08/26/2003 : 08:18:37 AM Does someone have ideas about how to draw a vertical line at x0 with specified height (such as sin(x0)). Thanks in advance. Jiang. quote: You can also use the draw command if you just want a vertical or horizontal marker... draw -l -v x0; // draw a vertical line at X=x0 draw -l -h y0; // draw a horizontal line at Y=y0 Mike Buess Origin WebRing Member
celarson	Posted - 03/05/2003 : 01:15:03 AM Thanks Mike, That is a somewhat more elegant solution. Also provides multiple line types, and arrowheads. Appreciate the help - I wouldn't have figured that out. -carl

celarson	Posted - 03/03/2003 : 6:37:18 PM Hideo, yes that's it exactly. This is how I have been doing it but was wondering if there was a built in "feature". I was hoping for a something a bit more elegant (like the graph function feature) but as long the +/- y values are suitably high then there is no reason this can't be the workaround. Thanks for your timely solution. -carl
Hideo Fujii	Posted - 03/03/2003 : 6:24:40 PM You can try the following: 1)Make two columns (in a new worksheet, say Data2, or in your existing worksheet) like: A(X) B(Y) 10 -1000 10 1000 Here, the range of B(Y) should cover your Y-axis scale. 2)Activate your graph window, choose "Graph:Add Plot to Layer:Line" menu, and include above X column (Data2_a) by "<->X", and Y column (Data2_b) by "<->Y" Hope this is what you wanted.
