// 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 Series Value Modifier

SeriesValueModifier allows you to display the last series value as a marker on the YAxis. This modifier automatically creates one marker per series and places it at the series latest Y-Value on the Y axis. This feature is often used in Trading and Financial charting applications.

// Source Code

The full source code for the Android Series Value Modifier example example is included below (Scroll down!).

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

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