In the docs for PowerChart it says:

- **rangeStartDate** : Start date for the modified chart data range that the user has selected, either with the range brush or by panning/zooming. Read-only. Value is date.
- **rangeEndDate** : End date for the modified chart data range that the user has selected either with the range brush or by panning/zooming. Read-only. Value is date.

but these values seem to only ever depend on the panning/zooming? Selecting range brushes doesn't seem to do anything, and I need these starts and ends for some scripting I'm doing. Is this a bug?

Running on an 8.1.43 Gateway

By chance I happened across the same issue as you. Unfortunately I think we're out of luck in this case

> End date for the modified chart data range that the user has selected either with the range brush or by panning/zooming. Read-only. Value is date.

My guess (and it's only a guess, mind you, i'm not any sort of IA guru) is that this is completely separate from the range brush. I can see why having the range exposed somewhere would be **very** nice to have if you're working with ranges. Fortunately, I think you're in luck, it _is_ exposed! Check this out!

the range brush start and end values appear to be in existence!  
I don't know if they'd be write-able, but they're certainly read-able.

Thanks! Yes, I was able to sort of use this, unfortunately there doesn't seem to be a way to tell which range brush the user has selected, which is the main behavior I need that the documentation says this should do.

Actually, now that I think about it, I think it means the range selector below the power chart? That would explain why range brushes don't do anything.
