How do I get limits on my XY graph?

[andyzoumas]

I am plotting some data on an XY graph. I need to put in an upper and lower limit line on the graph. Should I do this programatically (how?) or is there a way for it to be done on the front panel? I tried to bundle the X data, the y data, and the constants all in one bundle. didnt work. Any help would be much appreciated
Thanx
Andy

You could do this by positioning the cursors where you want them (i.e., set the cursor x position to the x limit value and the cursor y position to the y limit.) Use property node (LV6), attribute node (LV5). If you need more than one set of lines just add cursors.

jwf,
I have a property node already running because I am adjusting the X scale. I found cursor position but its not working for me. It wants a DBL for X and Y but I want one solid line going accross the graph at my boundary. Sorry, Im new to labview
Thanx Andy

You may need to make the cursor visible by writing true to the visible property. The x coordinate will set the position of the verticle cursor (set it off the graph if you don't wish to see it) the y coord will set the positiion of the horizontal cursor.

I just cant get it to work. Here is said VI in 6i. Please tell me if i've done anything dumb. Thanx

obviously they dont have an attach function LOL sorry. So if i set a Y cursor do I have to set an X cursor?

Hi
See the limits as extra graphs, in your case as a start-x,stop-x in an array clustered with an array of start-y and stop-y
this twice (upper and lower bounds) and build an array out of the three clusters
(original graph with 2 limit graphs)

Thanx for the help. Unfortunately, Im not getting it. Do I have to make 3 individual clusters? And then combine them together? Please clarify, sorry Im a novice

Here is Example of how to to what I suggested in other post
