Multi plot cursor in Mixed Graph

[RajGru]

If Digital waveform and normal waveform graph is plotted in a mixed graph, and if I choose watch all plots(multi plot) in cursor, LabVIEW closes immediately with an error popup dialog

I have attached the print screen image of that error popup

Hi Rajaa,

You might be onto a bug.  What version of LabVIEW is this happening in?  Also, when you reopen LabVIEW do you have an option to create an error log or report the error to NI?  Finally, could you post this VI so I can try to replicate the error?  Thanks and have a great weekend.

Jared Boothe,

         Thank You for your reply

         I am using LabVIEW 8.2.1. This problem occurs both in run mode and debug mode of a VI(while choosing multi plot cursor to watch all plots).

         I need to display both analog and digital waveform in a single graph and allow the user to analyse the graph data using multi plot cursors.

         It also crashes when highlight execution is on.

         But when I restart the LabVIEW,  I don't get any popup message asking if you want to investigate an internal error.

         I have attached the VI, that produces an error.

Hi Rajaa,

Looks like a bug in 8.5 but fixed in 8.6.  Have you had any consideration of upgrading in the near future?

Hi Stephen,

           I found a considerable solution to overcome that error.

           Build all the array data at first and then generate digtal waveform in single instance.

           ie., With number of numerical array data, build a 2D array of numerical data and make a transpose and then generate a waveform.

           It generates number of digital waveform equal to that of the column size of 2D Array.

           Do not build generated digital waveforms. This creates an error while using multi plot cursor--> watch--> All plots.

           I have attached the modified, bug removed Vi with this message for your reference.

Hi Raja,

               Can you post the vi for 8.0?

Hi Muks,

         Currently I am using 8.2.1.

         I don't have 8.0

Rajaa,

Thanks!  I'm sure this will be usefull for any other customers who are experiencing the same issue.  Muks...I saved it in 8.0 for you and have posted it here.
