| 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? |

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.

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.

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

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.

Does someone have ideas about how to draw a vertical line at x0 with specified height (such as sin(x0)).
Thanks in advance.
Jiang.

Hi Jiang,
This will draw a line from (X0,0) to (X0,sin(X0))...
draw -l {X0,0,X0,sin(X0)};
