We have one scenario in which we're adding a series for the purpose of using it in the 'sort by', specific example: A "Thing" goes trough "Stages" (e.g. Open Doing, Done, Closed). These Stages have a particular order. We'd like a chart of number of Things per Stages. Right now we the sort by options would only allow us to sort by the Value or the Stages (alphabetically). What we'd like is to be able to provide the order we define. There are two workarounds but are not ideal: 1. We can do stack bars and put the Order value on top and then change the color to match the background. Issue with this is that because the color is not transparent then it removes the grid lines so it does look somewhat off 2. We could prefix the Stages' names with a number. In some cases this also looks off So the proposed request is to add a way to Sort By a Field that is not being charted
