Trend self-resetting the scale

Good morning,

when i use the ZOOM button to see a small part of the trend with the processa analyst, after few seconds the view get back at the beginning view loaded from the PAV file.

This issue happen when i use the function ProcessAnalystPopup().

Do you have any idea of why this happen and how can i fix?

Thank you

  • Hi Stefano,

    Your description is a bit hard to follow as I'm not sure whether there is a problem being described or its the default behaviour of the PA you want to change.

    Without seeing your project and maybe a video of the issue I am just guessing.

    You can of course configure the PA to not Autoscale the vertical axis for all / or a specific pen. Is that what you are seeing?

    By default the PA does two requests for a trend: Info request and a data request. The info request is where all the trend meta data (such as configured scales) are retrieved and applied to the pens - this could take a second or so depending upon how hard the trend server is working.

    If you are not quite getting the result you need, give Support a call so you can demonstrate the issue and they can go from there.

    Cheers,
