How do I add a crosshair marker to a plot using SKILL?

kitmonisit

I can see the functions awvPlaceXMarker and awvPlaceYMarker, as well as awvCrossHairDeleteList.

How do I add a crosshair marker that's identical to what I get when I press M in a plot? I could use this in conjuction with value() and cross() functions.

    There's currently no SKILL API to add point markers, unfortunately. Please contact customer support - I'm pretty certain this is in the list of things requested (we plan to tidy up the various SKILL interfaces to ViVA as there are a lot of legacy functions which date from the old AWD days, and also new functionality in ViVA which requires a clean API to access them; however, the first focus was to get the new ViVA graph solid and with a clean use model, and then add the SKILL interface afterwards).

    Kind Regards,

    Andrew.

    This seems to still be an issue, 4 years later.  Are there any plans to fix this?  I just submitted another support request for it.

    Andrew:

    Actually, support pointed me to the following function that seems to work ok.

    awvPlaceWaveformLabel( awvGetCurrentWindow() 1 list( 1.2u 200m ) "PointMarker %X %Y" nil)

    I wish there was a way you could specify the marker according to the Y value, an option available when editing a marker in the gui.  The function above will set the marker at x = 1.2u and Y = Trace1 Y Value  (not 200m)

    Curtis - I've learned something. I'd never have guessed that the old waveform label creation function created markers!

    I still have an action (from R&D) to propose a new ViVA-centric API to interact with the graphs - and I have one designed in my head - just need to translate it into a proposal for R&D. Hopefully I'll have time soon to get to that...

    Andrew, did you ever make any progress on this? Would still be nice to have an API.

    I had discussions with R&D about what this might look like, but it's not reached fruition yet.
