SciChart® the market leader in Fast WPF Charts, WPF 3D Charts, iOS Chart, Android Chart and JavaScript Chart Components
The Xamarin Realtime Ticking Stock Charts example demonstrates how SciChart library is suitable for real-time trading and stock chart apps even in demanding, live markets.
In this example you may see Ohlc or CandleStick charts updating in real-time. There are also two lines showing two moving averages. You may also see annotations used to show the latest prices on the YAxis.
The data updates in real time. In Android native we call OhlcDataSeries.append() and OhlcDataSeries.update() methods, to add new data to the chart when a timer ticks. Scrolling to the latest bar is handled in code by manipulating the XAxis.VisibleRange property.
In iOS native price data is updated in a SCIOhlcDataSeries in a timer callback. When the data updates, SciChart automatically redraws.
