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 Bubble Chart

Generates  an Android Bubble Chart in code. The FastBubbleRenderableSeries requires an instance of XyzDataSeries which contains X and Y points with position of the bubble and Z value which represents its radius.

Bubble charts are widely used in applications for investments, sales, marketing and many more.

Tip!

Bubbles are drawing using the pen set by the setStrokeStyle(PenStyle) method and the brush set by setBubbleBrushStyle(BrushStyle) method. Also you can adjust scale factor for bubbles by using setZScaleFactor.
