Themes are new to VividCharts as of our American Pharoah (Dec. 2020) release.
We wanted to give our users more global control over the look and feel of their Slates, rather than requiring each element be styled individually. That's where Themes come in!
A Theme is a collection of Slate Styles, Slate Variables, and a Palette that, when selected, will globally apply the Theme's styles and colors to elements as they are placed on a Slate. This gives users an easier visual authoring experience in addition to providing a more cohesive and consistent look and feel to your VividCharts creations.
