Seven panels and a data source that install into the Grafana you already run. XmR and Xbar charts, capability indices, Pareto and box plots, and measurements read off a 3D model. 4 are open source. The other 4 need a commercial license.

Each one is a normal Grafana plugin. Install it, point it at any data source in your stack, and it picks up your theming, your dashboard variables and your alert rules. Grafana is the only thing you run.
Point it at raw measurements. It works out the mean and the control limits, then checks every new sample against them and flags the ones that fall outside.
Everything in SPC Chart, plus Nelson run rules, attribute charts, time-weighted charts and staged limits, for processes that change part or setup mid-stream.
The distribution behind the control chart. Bin your measurements, fit a normal curve over them, and read the capability indices against your spec limits in the same panel.
Location and spread in one view. Xf-Rf limits are built from medians and quartiles, so a single extreme reading does not move your control lines.
Ranks your defect codes by how much scrap each one accounts for. It counts and sorts the categories for you and draws the cumulative line on a second axis.
Read your measurements on the part they came from. Load a 3D model, attach characteristics to the features they belong to, and open a control chart from any balloon.
A progress bar, gauge or full bullet chart, small enough to tile across a shop-floor screen. The capability numbers sit on the bar itself.
What the SPC CAD panel queries. The SPC maths runs as nested SQL inside your database, so a model carrying hundreds of characteristics opens without pulling every raw row across the network.
SPC Chart is free and covers variables data: XmR, Xbar-R and Xbar-S, with capability indices. PRO adds attribute charts for count data, the Nelson rules that catch a drift or a shift while every point is still inside the limits, and the short-run methods for a machine that runs a different part every day.

The open source panels are published in the Grafana plugin catalog. Install them with the CLI, restart Grafana, and they show up in the visualization picker.
