We build a lot of reports and from time to time we bump into situations where we can't put all of the necessary information in one report because of commas.
For example I need to show numbers as spend, and as well for Google campaigns I need to include CPV feature. Since one cost per video in our campaigns is usually below one cent I have either normal numbers with 0.00 CPV (because it's 0.002e for a video), and otherwise if I add more commas my spend looks like 196.3600 euros which does not make sense.
Making two charts just to put them both takes too much space and overcrowds reports.
