Pat,

We’ve got a bug for that logged already. We had planned to implement it at one point, and added it to the Page Composer, but didn’t get the runtime part done, and forgot to remove the option in the Page Composer. Making it work across the different chart types is the tricky part. We’ll likely start with removing the option from the Page Composer, and add it back when if/when we add runtime support. I’m sorry for the confusion.
