Vision Library+ v2.1:
XY Plot+, Control Chart+ and Event Analytics Table+

Vision Library+ 2.1 adds three symbols: XY Plot+, Control Chart+ and Event Analytics Table+. Charts can show values in another unit and pan and zoom out past the loaded range, and filters can be preselected from a display link.

Product: Vision Library+ for AVEVA PI Vision Release: 2.1.0 Date: October 18, 2026

Viewing a display no longer marks it as changed, and many defects are fixed, among them an AF Table+ save that could delete table columns. If you are upgrading, read What changes when you upgrade first.

New symbols

XY Plot+

Plots one measurement against another, for example head against flow. It replaces the native XY Plot and keeps its data model.

• Retrieval per X data source with an explicit point budget; a notice reports truncated and dropped points, where the native plot silently stops at 10,000 records.
• Color the points by a third value from a Multi-State attribute, as bands or a gradient.
• Reference curves and regression: design curves from coefficients or pasted x,y pairs, and linear, polynomial, exponential, logarithmic and power fits with equation and R².
• Classify points against a curve, line or envelope, with counts in the legend.
• Gates and time trail: keep only the pairs recorded under a condition, and follow points in time order.

Control Chart+

Shows whether a process is in statistical control, with a status badge (STABLE, WARNING, VIOLATION, NO LIMITS). It maps the ProcessBook SQC settings.

• Chart types: I-MR, X-bar-R and X-bar-S.
• Limits from a baseline period, AF limit traits, limit data sources or the visible window.
• Rule sets: Nelson (all 8), Western Electric or Custom.
• Capability: Cp, Cpk, Pp, Ppk and Cpm, with a histogram and normal curve beside the chart.
• It checks rules only while a display is open and sends no alerts; use AF analyses and notifications for that.

Event Analytics Table+

Turns event frames into a summary table: rows per category, columns per summary, and a totals row.

• Dimension, Measure and Delta columns, including comparisons with a target.
• Top N with an Others row that stays last, also when a reader sorts.
• Cells colored by limits, as fills, gradients or progress bars.
• Click to drill down through the dimensions or to filter other symbols on the display.

New features

Charts

• Pan and zoom out beyond the loaded range on Combo Chart+ and Asset Time Series Chart+; the display time range follows on release.
• A-B ruler interval is shaded outside the rulers on the time-series charts and Quick Trend.
• Histogram+: binning rules, a Pareto mode and process capability.

Display units

• Show an AF attribute in another unit of its unit of measure, as the native symbols do, on the charts, Time Series Table+, the gauges, KPI Card+ and Alarm Sound+. Quick Trend follows the unit.

Filtering

• Preselect a filter from the display link, so one display can serve every notification e-mail.
• Default selection when the display opens, and a compact filter indicator.

Data entry

• Nothing is written to an unresolved data source; your edits are kept and a notice names the inputs.
• Replace and Remove act at PI's exact timestamp.

Tables and event frames

• Header text filters work the same in every table: case-insensitive, partial match, with wildcards.
• Events Table+: Apply Context applies an event's time range and asset in one click.
• Event Details: capture current attribute values of closed events.

Navigation and tools

• Navigation Menu+: a new item tree editor with drag and drop.
• Quick Trend: full Download menu (PNG, SVG, PDF, CSV, JSON, XLSX).

Fixes

• Viewing a display no longer marks it as changed, so you are no longer asked to save it when you leave.
• AF Table+: a save no longer deletes the table columns the symbol does not show, with their values.
• Manual Data Entry+: a failed reload no longer re-sends edits, and prefills never overwrite typed values.
• Manual Input Table+: typed cells on a new row are saved after a column rebuild.
• Toggle buttons: clicking the selected half no longer flips the setting.
• Unreadable AF multi-state limits no longer stop the gauges, Heatmap+ or Asset Comparison Table+.
• Alarm Sound+: a value in alarm stays in alarm, and a click acknowledges only the running alarm.
• Gantt Chart+: every visible row is labeled again.
• Many smaller fixes across the charts, tables, gauges and navigation symbols.

What changes when you upgrade

Saved displays are not rewritten and keep rendering. You may notice these changes:

• Filter indicators are compact by default; set Filter Indicator to Full for the 2.0 chip.
• Header filters match more rows because they now match part of the value and ignore case.
• Asset Comparison Bar Chart+: horizontal charts read top-down; turn off Inverted if it was a workaround.
• Retired options: the Event Comparison Chart+ trellis layout renders as Split, and the Map+ Pie series type shows markers.
• Alarm Table+ and Asset Comparison Table+ no longer save viewer filters, sorts and column widths; set defaults in PI Vision edit mode.
• Defaults for new symbols only: Apply to display time is on for new Combo Chart+ and Asset Time Series Chart+.

For administrators

• Start from the new config.js and merge your site values into it.
• PI Web API request pacing: large event frame loads now slow down and retry instead of losing values.
