need cursor value from graph to use in block diagram

[gatordan82]

OK I edited it a lil bit so it would "compile."  And it's real close to what I want...any thoughts.

I would keep the full data on the left graph, and only show the cut data on the other two.

1. Your FOR loop has no purpose whasoever.
2. To get an array subset, use "array subset" not "delete from array".
3. Don't duplicate code. You only need to read the cursors once, not three times in paralell. 🙂
4. Use switch action, else the cut will revert in the next iteration.

See attached... (LabVIEW 7.0)

In one of your earlier posts I got the impression that you wanted to look at the subset and possibly cut further from that. If so, replace the tunnels where the arrays enter and leave the while loop with shift registers. This is in addition to Altenbach's comments. I don't have LV7.0 running right now so I cannot post the mod in your version.

yes, you are correct...I want to further delete more of the array.  That was the whole reason for having the for loop so I could use the shift registers to pass the cut array back into the loop for MORE CUTTING.

Sorry, my mistake. I thought you wanted to keep the data between the cursor, not delete them. So, yes, use "delete from array" for your stated requirements. 🙂

If you're all interested I've attached my final version.

This was the first program I've written in LV ( from scratch).

Thanks everybody for your replies and for you help.  I truly appreciate it.

Your FOR loop still has no purpose at all. Why do you think it is necessary?

Now, as the next exercise, wrap the entire thing into a nice event driven state machine, including states to read a new data file, save the trimmed file, undo a clip action, stop the program, etc. 😄

hi

how to program my requirement.

i.e. get the two x-axis values automatically from the graph.

please give an idea to this.

i attached my requirement as image

(You probably should have started a new thread, because your problem has nothing to do with cursors.)

Also, please attach a typical dataset and the expected result. A there always exactly two spikes?

[thinnker]

Hi

This graph mesaures a time between two sensors outputs.

The graph contains only two spikes from two sensors.

I need the time period between two spikes only.

I am not able to create new thread.

I can place dataset if you create new thread for me.

Hari
