SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
SciChart Android ships with ~90Â Android Chart Examples which you can browse, play with, view the source-code and even export each SciChart Android Chart Example to a stand-alone Android Studio project. All of this is possible with the new and improved SciChart Android Examples Suite, which ships as part of our Android Charts SDK.
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.
The full source code for the Android Custom Chart Theme example is included below (Scroll down!).
