%V\ (%EV) to plot under Control Chart

The post Exception Value (EV) Metrics and Technical Analysis Indicators

introduced EV based metric (%V\) that I promised to find a good application for. And I did. That should be a needles (or bars) type of graph under the main control chart to mark hours that had anomalies (exceptions). Actually that idea was suggested by one of this blog guest poster (STEEDd: Another Implementation of The Near-Real-Time Control Charting and EV Calculating).

And also I have already used the similar idea to build EV-Control Chart
See example:
