I am using a Measure to set the Size for circles in a scatter plot. The numbers are millions or billions. A Legend appears. It shows the full number for the range of sizes (7,891,234,000) for example. I'd like to Format these numbers in a manner similar to other numerical fields, using a M or B designation. (7.8B or 7,891M) But Format for Legends does not include this option. And, if I Format the underlying Measure, it does not carry over to the Legend.
