Currently, Event Comparison trend has 0 configuration options.  I need the ability to show markers or a scatter plot similar to the pop up trend/ad hoc workspace.

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.

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.

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.

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.

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

Sometimes there are very long event frames in the event comparison and it would be nice to be able to set the width of the x-axis to cut these event frames off at a certain duration. It's inconvenient to have to manually exclude them, and sometimes one still wants to look at long and short event frames in the same display.

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.

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.

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.

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.

Currently in the event frame comparison page, you can hide event frames from trends by right-clicking on the event frame and selecting the hide option.

It should be easier to hide events quickly: Optimize the way events can be hidden or provide the ability to hide multiple event frames in one go instead of one at a time.

Allow configuring event comparison displays in an ad hoc way so that the search criteria and the attributes shown can be set through URL parameters.

For example: As an operator, I would like to receive email notifications with hyperlink URL pointing to the correct Events Comparison display, along with configurable search criteria.
The same automation could be used in an iFrame inside a 3rd party application to open (inside the iFrame in Kiosk mode of course) a related and contextualized Events Comparison display with targeted search criterias or using a simple mouse-over.

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

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.
