I saved a chart in draft form, and then didn't need the chart (it was a blank document I just accidentally hit save as draft). I went back into the chart to delete the draft and there is no option to delete (the box on the ipad is a blank white box, where it normally says "delete" when you click the 3 dots in the upper right hand corner. Also no option to archive. I also tried on the desktop computer and there was no delete option available
