Currently the y-axis options are Auto, Database, and Custom. The problem with Database and Custom is that they are static and fail to capture unusual events outside the normal expected range. The problem with Auto is that during normal operating times it tends to zoom too far in, thus highlighting some normal fluctuations. A combination of Custom/Database and Auto would be very useful. Allowing the axis to expand during the unusual time frames but then restricted it to only shrink back to the Custom/Database settings. Thus preserving the original context.

It would be useful to be able to implement a logarithmic scale to either/both axes of xy plots. 

Specific use case: Diagnose well conditions in real time by looking at conditions based on elapsed time since an event frame.  To be able to identify trends and perform diagnostics, this will need to be plotted as log Y vs log X (elapsed time).

As a user of PI Vision, I would like my asset comparison table objects to not show "No Data" when I compare differing assets that do not necessarily share all of the listed attributes.  I would rather they appear as blank boxes as it more appealing to the user and gives them a better understanding of the actual asset behavior.

As a PI Vision user, I want to trend relational or time-series data from an external ODBC data source alongside my PI data on a PI Vision display.

In the Table column option could the Total also be included?

Drive a multistate symbol on a display from an Event Frame context. For example, turn the circle red if a 'Downtime' event on the asset is currently active.

Support for a linear regression lines on trends, similar to what was available in PI ProcessBook.

As a display author, I would like to configure the format of a regression like (e.g color and line weight) so that the regression line stands out from the points on an XY Plot.

A tool that I have had many uses for is a calendar view tool that shows attributes, tags and the ability to MultiState them in a properly formed calendar.

Attached is an example that we had to build with some other web controls talking to PI Web API.  I have several cases where this type of display tool in Vision is required.

With future tags and predictive data growing since PI 2015, it is good that PI Coresight can accept future tags.

However, rarely do these data come as a discrete value. They usually have an associated prediction interval/uncertainty. For that reason, I put forward this enhancement request:

The trend symbol needs to be able to accept an upper and lower bound and display a shaded region. E.g. https://www.knowledgeminer.eu/img/composite_2.png

Pie chart showing cumulative duration of event frames by event type for an asset(s) over a time period (ex: 24 hours).

Trying to determine how much time you've spent in particular states over the past day.

Be able to change a symbol shape and color. For example, green circles, orange triangles, red squares. This will help colorblind users.

Be able to put symbols inside of table rows.

Similarly to the XY plot, a XYZ 3D plot would be useful to inspect the trend of 3 variables in a 3D space and visually deduce correlations. Example could be the Environment Temperature, the Gas Valve Opening, and the Produced Power of a gas turbine. This graph should also be filtrable (e.g. I only want to see this data when the machine is operating under maximum power conditions).

Highlight the PI Vision trend section that above/below the limit by changing the color of the trend in that section. Limits can come for PI AF (traits) but there should be an option to configure limits from PI Vision too (similar to how you configure multistage symbols).

Be able to see the details on a multistate when selecting or on a hover. Details include: attribute name, current value, timestamp.

Please add pie chart (circle chart) symbol with option to see current value.
