I am using Odoo 16. I would like to know the following
1. Can we can add gradient effect for the  Bar graphs. If so how could it be done.

2. Also would like to know how can we give custom colors for the graphs. I noticed for graphs the color is referred from 'COLORS_BRIGHT' or 'COLORS_DARK' list defined in colors.js. I would like to know how to override the same.
