The built-in gauge is one fixed shape. If you need a 270-degree arc, more than one value on the same dial, or a marker showing where the value should be, there is nowhere to configure it.
This one lets you set the arc, stack rings for related values, and add a ghost pointer for target or previous value, so a single dial can carry the comparison instead of needing two.
Download the package
Purchase the symbol at piforge.app and download the ZIP from your profile. It contains four files: the symbol script (.js), two templates (.html) and an icon (.svg).
Copy the files to the PI Vision server
Extract all four files into the PI Vision extension folder on the server: %PIHOME64%\PIVision\Scripts\app\editor\symbols\ext\ (create the ext folder if it does not exist yet). Use %PIHOME64%, not %PIHOME% — on a PI server those are different trees and PI Vision is only in the 64-bit one.
Restart the PI Vision application
Recycle the PI Vision application pool in IIS (or run iisreset), then hard-refresh the browser (Ctrl+F5) so the new symbol script is loaded.
Add the symbol to a display
Open a display in edit mode. The new symbol appears in the symbol palette on the left. Select it, then drag a tag or AF attribute onto the canvas.
Activate the license
Open Format Symbol, paste the license key from your purchase email into the License field, and save. The watermark disappears immediately — no restart needed.
Live Display
Needle, multistate arc zones, zone-colored center value
The needle sweeps live while the big center value takes the color of the active zone — readable across the room, on light or dark displays.
Ghost Pointer
A faded marker shows the past value — with Δ on hover
The ghost pointer marks where the value was N minutes ago. One glance answers the question every operator asks — no trend chart needed. Hover for the exact past value and delta.
Gauge Angles
Start angle and sweep are just two numbers
Classic three-quarter gauge, a compact semi-circle for headers, or a full ring for modern KPI tiles — set start and sweep and the ticks, zones and indicators re-lay themselves out.
Multi-Ring
Concentric rings with a color-matched center legend
Drop several tags and switch on Multi-Ring: each becomes its own concentric arc, with a color-matched legend and values in the center. Compare related KPIs in the footprint of one symbol.
Indicators
Pick the style that fits the story
A classic needle for process values, a progress arc for completion KPIs, a quiet marker dot for references — each indicator picks its own style and color.
Zones
Arc segments + center value color from one editor
Zones are simple from-to-color rows. Move a boundary and the arc repaints, the center value recolors, and your operating envelope is documented right on the gauge.
It marks a second position on the same dial — a target, a setpoint, or the value at a previous time — so actual against expected is one glance rather than two symbols.
Yes, as concentric rings on the same dial, which keeps related measurements physically together on the display.
Yes — PI Vision 2019 R2 through 2023+ are supported. The symbol uses the standard PI Vision extensibility model, so regular version upgrades do not break it, and one year of compatibility updates is included.
No. The symbol is installed once on the PI Vision server; every browser client gets it automatically from there.
One license covers one PI Vision server, with unlimited displays and unlimited users on that server. The key is delivered instantly by email after purchase.
Every feature is demonstrated in live video on the product page, and a free symbol (Combo Chart Free Edition) is available on GitHub to validate the install workflow end to end. If you need a formal quotation or have to go through procurement, use the Request a Quote button on the product page.
