Hi,
The user has very specific color requirements for a stacked bar chart. They have provided the RGB #s for each (one bucket = one colour of the stack). Example:
| Bucket | Red | Green | **Blue
** |
| 1 (BK 0 90) | 225 | 39 | 38 |
| 2 (BK 91 180) | 0 | 169 | 142 |
| 3 (BK 181 270) | 240 | 170 | 33 |
Is there a way to set the colour of each "stack".
Here's what it currently looks like with the default coloring from Apex:

Each "bucket" is it's own series. There are 8 series in this example.
