The Stock Chart is represented by the StockSeriesView object, which belongs to Financial Series Views (which are also called Low-High-Open-Close ).
This view is used to show variation in stock prices over the course of a day. The Low and High prices are represented by the bottom and top values of the vertical line which is shown at each point, and the Open and Close prices are represented by left and right tick marks, correspondingly.
For Stock charts, you can choose for which price level (Low, High, Open, or Close) to enable the FinancialSeriesViewBase.ReductionOptions, meaning that in case the specified price is lower in comparison to the previous point’s value, the subsequent point is painted red (or any other color).
A Stock chart is shown in the image below. Note that this chart type is based upon the XYDiagram, so it can be rotated to show bars either vertically or horizontally.
To learn how to exclude holidays and weekends from an axis scale, refer to Work Time and Workday Configuration.
For more information, see Financial Charting.
The table below lists the main characteristics of this chart type.
| Feature | Value |
|---|---|
| Series View type | StockSeriesView |
| Diagram type | 2D-XYDiagram |
| Number of arguments per series point | 1 |
| Number of values per series point | 4 (Low, High, Open, Close) |
Note
For information on which chart types can be combined with the Stock Chart , refer to the Series Views Compatibility document.
This example creates a ChartControl with a series of the StockSeriesView type and adds this chart to a form at runtime. Before you proceed with this example, create a Windows Forms Application in Visual Studio and include all necessary assemblies in the References list of your project.
