control more cursors in XY graph

[weizbox]

Im currently working on somthing that requires me to control the locations of many/unknown number of cursors on an xy graph. I can control up to 9 so far (0-8), but in the block diagram when I unbundle the CrsList Property of the XY graph, I can only go as far as 08.Location, and then just stops and wont even start listing cursor 09. I have LabView 6.1 right now, if this has changed in 7, please let me know, or if not, if there is a way around this problem.

Thanks,
Mark

Hi Mark,

you can have as many cursors you want. Look at my example which will generate a new cursor each time you go through the loop. I clicked 23 Times on the "Next Cursor" and got 23 cursors.

Creating many cursors doesnt seem to be as much of a problem as being able to tell the cursors where to go once they have been created... thats really the problem that im running into.

Thanks,
Mark

It sounds like you are casting the LV array of cursors to a cluster and
using unbundle by name to access them. Problem is that the array to
cluster convertor has to create the same size cluster each time and
defaults to nine elements.

If you want to change this to a larger number,
right click on the
convertor and change it to a larger constant. If you want it to be
completely dynamic, don't convert and work on the array instead.

That is what i was doing. Thanks a lot, that really helped me out 🙂
