Internationalization involving rtl languages
A suggestion I would make in the Internationalization context would be an overall rtl chart command which would call into action a group of these piecemeal xAxis reversals, navigator xAxis reversal, yAxis oppositeness, rangeSelector positioning, and input positioning. In the same vein as setting rtl in your <body> tag. Perhaps the chart should even take a hint from the enclosing div’s direction tag in lieu of requiring this explicitly. Now, that would be a clean rtl interface!
Positioning of the rangeSelector buttons: they should move and reverse so that they begin on the right side and progress leftward.
Also, the input boxes should reverse their positioning.
