This is the example / showcase application for the MPAndroidChart chart library / graph library on GitHub: https://github.com/PhilJay/MPAndroidChart
The library this app showcases (MPAndroidChart) is designed to create beautiful visual representations.
The core features of the library include:
 - Many different chart types: LineChart, BarChart (vertical, horizontal, stacked, grouped), PieChart, ScatterChart, CandleStickChart (for financial data), RadarChart (spider web chart), BubbleChart
 - Combined Charts (e.g. lines and bars in one)
 - Scaling on both axes (with touch-gesture, axes separately or pinch-zoom)
 - Dragging / Panning (with touch-gesture)
 - Separate (dual) y-axes
 - Highlighting values (with customizeable popup-views)
 - Save chart to SD-Card (as image)
 - Predefined color templates
 - Legends (generated automatically, customizeable)
 - Customizeable Axes (both x- and y-axis)
 - Animations (build up animations, on both x- and y-axis)
 - Limit lines (providing additional information, maximums, ...)
 - Listeners for touch, gesture & selection callbacks
 - Fully customizeable (paints, typefaces, legends, colors, background, dashed lines, ...)
 - Realm.io mobile database support via MPAndroidChart-Realm library
 - Smooth rendering for up to 10.000 data points in Line- and BarChart (tested on a 2014 OnePlus One running Android 6.0)
 - Lightweight (method count ~1.4K)
 - Available as gradle dependency and via maven
 - Widely used, great support on both GitHub and stackoverflow - mpandroidchart
 - Also available for iOS: Charts (API works the same way)
 - Also available for Xamarin: MPAndroidChart.Xamarin
This project is meant to demonstrate the features of the library and motivate developers to make use of it. This is not an app to create charts.
