This visual, like the R package it is based on, supports the NHSE/I programme ‘Making Data Count’, and allows users to draw XmR charts, use change points, and apply rules with summary indicators for when rules are breached.

As it is a standalone custom PowerBI visual, rather than an R script, you get an interactive graph that users can hover over to obtain more information about individual points.

The relevant variables from datasets can be dragged in to the PowerBI interface.

It is then possible to set things like a plot title and axis settings via the interface.

There are a range of different options for displaying the SPC chart.

Single Plot

Faceted Plot

This is particularly useful if you are filtering and different groups may have a different number of KPIs to plot

Cards

In place of a metric card that only gives a current value, these cards provide the variation icon, the target icon (if relevant), and a sparkline. Users can then choose a title and subtitle for the card.

Summary Tables and Matrices

For a high level overview of multiple metrics, you can use one of the summary table or matrix layouts.
