Description
The Control Chart XmR for Power BI is actually two charts. The chart called the X-chart is the first. This chart displays the actual results and the bandwidth of “normal” values. The chart called the mR-chart is the second. This chart shows the difference between consecutive data point measurements. The two charts together allow the user to separate the noise from the real signals. These charts will help you to focus on the real signals and ignore distracting noise.
The upper chart (X-chart) displays the data-points over time (Actuals) together with a calculated average (Average – center-line (CL)). The X-chart also determines the Upper and Lower Control Limits (the bandwidth). The lower chart displays the Moving Range (mR-chart) with its Average and Upper Control Limit.
The Control Chart XmR can calculate all the derived figures automatically. It can even detect the signals in your data. The rules being used for the automatic signal detection and recalculation are:
- 7 points in a row are above or below the center-line
-
10 out of 12 points are above or below the center-line
-
3 out of 4 points are closer to the UCL or LCL than the center-line
You can also override the automatic calculation by applying your own derived figures from data. This gives you complete freedom to implement your own rules for detecting signals.
