// 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 Chart Custom Tooltips

In SciChart Android, it is possible to customize the look and feel of Tooltips for our Android charts. This examples demonstrates how to do this using TooltipModifier.

Tip!

What can be customized? The actual tooltips style (background, size, opacity) as well as text style (font family, font size, weight, text color). The marker which intersects the series, and also text formatting of the tooltip itself.

// Source Code

The full source code for the Android Chart Custom Tooltips 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 from the Java version of the SciChart Android Examples app.
Also the SciChart Android Trial contains the full source for the examples (link below).
