Light and Dark Mode

Problem:

We have a dark and a light version of our website. Is it possible to change chart backgrounds to match? i.e. black background for dark mode and white background for light mode?

Solution:

Yes, it is possible to change chart backgrounds/theme to match i.e. black background for dark mode and white background for light mode using the modify method that modifies any part (object) of the current graph. Attached is an illustration and demo for your reference.
