Chris Rice 10f934d287 Add alpha color channel support for graph bars (#10956)
* Set fillColor in bars on load and on color change

* Change bar fill color on color override

* Added test for series overrides

* Moved bars fill color setting into time_series. Fixed issue with prev commit where you could not show bars because of series overrides.
