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 Use Palette Provider

Demonstrates how to use the PaletteProvider API to color lines and points individually.

Tips!

Using this API you can color individual data points of the following RenderableSeries:
– FastLineRenderableSeries
– FastMountainRenderableSeries
– FastBandRenderableSeries
– FastBubbleRenderableSeries
– FastCandlestickRenderableSeries
– FastOhlcRenderableSeries
– FastImpulseRenderableSeries
– FastColumnRenderableSeries
– XyScatterRenderableSeries
– FastErrorBarsRenderableSeries and FastFixedErrorBarsRenderableSeries
– FastUniformHeatmapRenderableSeries

Android Use Palette Provider

// Source Code

The full source code for the Android Use Palette Provider 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).
