Trend: Scale grouping

On the trend symbol, we would like to select specific tags to share a single scale which auto-updates, while the other tags use independent scales. All on the same trend. For example on the same trend, • PICXXXXXX.PV & PICXXXXXX.SV need to share a single scale which auto-updates using the range of their plotted values. • PICXXXXXX.MV & ZTPXXXXXX.PV need to share a single scale which auto-updates using the range of their plotted values. • Tag PICXXXXXX.MODE needs to be on its own axis scale The solution provided for the idea titled "Trend: Shared dynamic scales" creates a single scale but it does not auto-update using the range of plotted values.

    This is a basic function in Excel and I'm not sure why it isn't included in PI Vision

    I want to point out that a request from Shell is that one lower range could be fixed while the multiple 'scale-with' ranges are applied. For example, the lower range set to 0 while other groups are scaled-with each other and the higher range is automatically adjusted based on the output value.

    I'll also ask others to share more details of the specific requirements.

    Why doesn't this functionality already exist! Would allow for more info on one trend view. This is a great addition to the tool.

    This feature would greatly enhance the functionality of PiVision for process control applications, where its is often very helpful to have Controller PV and SP trended together on one dynamic scale with Output on the same trend but different scale.

    This idea is definitely something I would use to allow me to use divergent unit types on the same graphs. Today I do not do that using multiple plots where information may be better shared, sometimes, on one graph.

    Lack of this feature is stopping me from using PI Vision. I want to scale the process value and setpoint on the same scale and the output on a different scale (%), while having all 3 on the same trend.

    This would be a good addition for PI Vision. We want users to be able to start analyzing data and not have to tediously setup manual axis that don't update. We have a heritage plant data viewer that allows autoscaling of 2 variables on the same axis while setting a third variable to its own axis or autoscale itself on the same trend similar to those attached. One feature not seen in many auto scaling setups is the ability to fix MIN or a max ....ie. I would like to fix my OP min scale to 0 but let the max change as dictated by autoscaling. Another feature is setting a min autospan ie autoscale but do not decrease span to less than a value like 10% or 10 gpm.... using these settings helps take a lot of noise out of trends. . thanks for considering.
