Charts often benefit from showing upper/lower control lines that show a certain number of deviations from the average. A common example is a funnel plot, essentially an extension of a bubble chart but allowing individual series to have their own plot. See here for an example in Excel:http://www.kurtosis.co.uk/technique/funnel/index.htm

Great idea, Michael. I think the key elements of this are the upper and lower control lines and the central average. They're valuable additions to any chart, not just a funnel plot, so I've updated the title to reflect it. Please keep voting if you think this would be helpful!

RE: Add Upper and Lower Control lines to charts
Very helpful for large scale data allowing the consumer to quickly identified anomalies of known upper and lower limits of a system. Excel allows you to build the Upper/Lower limits while I can't seem to find how Power BI supports this capability.
RE: Add Upper and Lower Control lines to charts
Yes, I think that is useful
RE: Add Upper and Lower Control lines to charts
Is this still under review? Looking to build some Statistical Process Control charts, and this would really be nice.
