WPF Chart - Examples
SciChart WPF ships with hundreds of WPF Chart Examples which you can browse, play with, view the source-code and even export each WPF Chart Example to a stand-alone Visual Studio solution. All of this is possible with the new and improved SciChart WPF Examples Suite, which ships as part of the SciChart WPF SDK.
Demonstrates a multi-series chart using the FastCandlestickRenderableSeries with three FastLineRenderableSeries showing the moving average of the closing price.
The example uses the CategoryDateTimeAxis which collapses overnight and weekend gaps in data, but, uses the Index to the data to calculate X-position. This means that all DataSeries must have the same number of data-points (you can pad DataSeries using double.NaN for null or empty points).
Example Usage
– ZoomPan, left-mouse drag to pan the chart
– Mousewheel, roll the mousewheel to zoom
– ZoomExtents, double click to zoom to extents
Tip! To get the effect of hiding the line for the first N points of a moving average, you can insert double.NaN into the XyDataSeries. double.NaN can be used to render gaps or continuous lines.
