As a Charts user, I would like the ability to easily select all of the time series with a check box of some sort and then delete all that I’ve selected, rather than having to delete one at a time.
As an example, I duplicated someone’s public chart and wanted to replace the time series that feed into the calculation with different tags. There were a lot of variables, so it took a long time removing each time series that needed to be replaced by having to go one by one.
