Description
I'm working on styling for my charts and I'm wondering if there's a good way to highlight / grey out / mark after hours trading periods in some way like some graphing programs do.
Here's an example of one of my charts at the moment:
Here's a quick photoshop markup of what I want to do:
I'm currently pulling from an api that gives data on a multitude of periods and intervals. I saw there was functionality for highlighting between timestamps with the fill_between feature. However, I'm a bit stumped on how to make sure I cover all after hours periods in any given period. Any pointers in the right direction on doing this properly would be greatly appreciated!
