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.
Demonstrates the use of the SeriesSelectionModifier, which hooks into the ChartModifier API to select series when you tap on it.
Tip!
The selected series is styled via the setSelectedSeriesStyle() method of SeriesSelectionModifier. A blanket style applied to any series which is selected. Also you can use the setSelectedSeriesStyle() on any RenderableSeries to achieve the same effect on an individual series level.
The full source code for the Android Chart Series Selection 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).
