SciChart ships with 8 stunning themes, which you can apply to your charts with a single line of code. This example shows how to style SciChart with your own custom theme, and how it affects default cursor, zoom, axis, grid and series colors.

To include a custom theme in your application, add styles to a resource file in styles.xml, ensuring all the keys are entered for the SciChart theme (see styles.xml). After that, the theme can be applied to SciChart in a single line of code.

Tips!

To define your custom theme you need to override a bunch of drawables and colors and provide a file with style attributes or you can implement IThemeProvider interface on your own.
