NoTmE

Hah, thanks for that addition, but I already know how wait per multiple of 10 ms (forgot to include it in my post). The problem I had was running the loops in parallel, but now that I ran the example for the first time on my computer, I realized that it runs perfectly in parallel if two different loops are used (DUH! I'm a moron...). Previously, I was trying to run the timer and the wait in the same loop in a different test program I made, so LabVIEW would not run it in parallel. I guess I automatically assumed that the same action would of occured using two separate loops. Thanks though, for I wouldn't of realized that LabVIEW automatically runs separate loops on the same frame in parallel unless I used the two loops in an example to post for help. stupid mistake, huh? again, thanks everyone for the help :thumbup:

Oh sorry about not posting code previously; I have attached an example now. It is without the queue structures so I can get fresh advice on how to run the timer and wait methods in parallel. EDIT: It is probable that I will have to undergo data acqusition in parallel of these two things as well. I have read somewhere that if dll libraries are used for DAQ (or anything), then they are automatically run in parallel. Is this true? If not, I would have to have another parallel loop for data aquisition, right? I want the data from, say, a digital thermometer of sorts, to update every 100ms or so.

i would like to have an elapsed time feature in my program, but i want it to update every 10-100 milliseconds. i need it to run in parallel with a variable wait (not after the wait is executed, because then the timer would update variably and probably less frequently dependant on the wait time). i have tried queueing, but i cannot get it to work. i think it has something to do with the enqueueing/dequeuing speed matching the wait time, correct me if i am wrong? i dont have a very strong knowledge of queueing, so this is a problem for me. so what method/structure would i have to use in order to do this? thanks in advance

Sorry if you misunderstood, but I already found out how to place multiple plots on an XY graph. Sorry about that. What I do need help with is enabling the user to place their own points and draw their own lines on a graph by using their cursor. I want the points to be returned to two separate arrays (one for x-values and one for y-values). This would be useful. Thanks.

Okay, I found how to transpose multiple plots on a graph; I was just too lazy too look it up . But I have not resolved the second question.

I have two questions today: How exactly does one make a multi-plot graph with two sets of data (as in two sets of x-values and two sets of y-values of array format)? I want the result to be in an XY Graph format (using LabVIEW 6.1 of course). In addition, is it possible to allow the user to place points on a graph as input and allow the coordinates to be returned to an array? If so, is it also possible for the user to draw a line on the graph and allow a certain number of points from the line to be returned? These may be simple questions but I would appreciate the help nonetheless :laugh:
