SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components

// Android Chart Examples

SciChart Android ships with ~90 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.

// Android Using ThemeManager Example

SciChart ships with 8 stunning themes, which you can apply to your charts with a single line of code. This example showcases the themes, and how they affect default cursor, zoom, axis, grid and series colors.

In addition, you can create Custom Themes

Android Using ThemeManager Example

// Source Code

The full source code for the Android Chart Using ThemeManager example is included below (Scroll down!).

Did you know you can also view the source code from one of the following sources as well?

  1. Clone the SciChart.Android.Examples from Github.
  2. Or, view source and export each example to an Android Studio project from the Java version of the SciChart Android Examples app.
  3. Also the SciChart Android Trial contains the full source for the examples (link below).
