Currently, Event Comparison trend has 0 configuration options.  I need to be able to: show markers, hide trendlines, set x and y scales, zoom in/out, expand trend to fill screen, set color schemes (running, completed, recently completed).  All things that BatchView BatchTrend in ProcessBook can do!  We can't move to Event Frame Comparison Trends in PI Vision until many of these items are added.

There is no ability to configure the Y-axis scales on the event comparison displays (database, autorange, custom). If there is an outlier value it can make the chart too compressed to see useful data.

It is currently possible to zoom in on event frame comparison using child event frames, but you cannot zoom in into an arbitrary location on a trend by dragging the mouse cursor.

From the event details or event comparison displays in PI Vision, it would be useful to export event frame data (including attributes and values) to CSV/XML.

On the event gantt chart, have the ability to show lines/time markers for the child events in the parent event gantt bar when not expanded. This way the user doesn't need to expand the gantt to get an idea of when the children occurred.

Add the ability to expand all/collapse all in the event gantt chart.

Provide a migration from PI Batchview displays in PI ProcessBook to PI Vision.

Ability to put multiple traces (like flow and temperature) on a single overlay trend, still with showing data from multiple events/ batches or comparison against golden batch/events.

When there is an Event Frame attribute that is calculated, i.e. the attribute has a “By Time Range” Value retrieval method of Total, Average, Maximum, Minimum, etc., PI System Explorer shows a single value for this Event Frame Attribute. In PI Vision displays, however, the underlying time-series tag data are displayed instead of the calculation result. I would like to view the calculated value instead of the underlying tag’s time series data in order to be able to compare values from different Event Frames.

As an engineer I want to be able to analyze past production using XY scattered plot using Event Frames result attributes as inputs. In this case the amount of painted dots on the plot would correspond to the number of Event Frames gathered by the search criteria (no time series per se).

For events with lots of children, do not show each child event on their own row on the Gantt Chart because it takes up a lot of vertical space for Events that have lots of children. Instead only go to a new row if the events overlap in time.

When an Event Frame is selected in Events Comparison Displays, the user should see a drop-down list instead of or in addition to the "Add Comment" text box.

This drop-down list should include possible comments (configured in the EF templates) that the user might select and add to the event.

As an end user, when going from related Events to the Compare Events page, I would like to see a check box which allows me to select which items to compare in the overlay trends.

Provide the ability to maximize/minimize trends in the Event Frame Comparison page.

I would like the option to plot summary calculation profiles (average, maximum, minimum of all the Event Frames currently in my Event Comparison) in order to compare each Event Frame to the average of the included Event Frames, i.e. if I have 10 event frames then I would like to display the concentration over time for each individual Event Frame (10 profiles) as well as the average concentration profile of all the event frames (1 profile). This is somewhat like a golden batch but is a statistically manufactured plot as opposed to being from a golden run.

If there are multiple pinned event frames in a Event Frame Comparison Display, each pinned trace should have a different color

Currently opening events comparison display does not force the tab to be shown in Events tab. When opening events comparison display (ad-hoc or saved), events tab is more natural fit for the display as opposed to Assets tab. Users can immediately jump in comparing different events.
Current(2016 R2) behavior is whichever tab/pane is open last time gets open again.

When viewing event comparisons, the Attributes pane only lists the event frame attributes, the referenced element, and the referenced element's attributes. It currently cannot drill down and trend child element's attributes.

When comparing similar events, add functionality to see not only the relative time since the batch began but also the exact date and time as you click around the trend.
