Stock Chart

  • 6 minutes to read

Short Description

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.

Chart Type Characteristics

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.

Example

This example demonstrates how to create a ChartControl with a series of the StockSeriesView type, and add this chart to a form at runtime. Before proceeding with this example, first create a Windows Forms Application in Visual Studio, and include all necessary assemblies to the References list of your project.

Then, add the following code to the Form.Load event handler.

Note that you can exclude non-working days (weekends and holidays) from an axis range, via the AxisBase.WorkdaysOnly and AxisBase.WorkdaysOptions properties. And, to learn which instruments for financial analysis are available in XtraCharts, refer to Indicators.

// ...
        private void Form1_Load(object sender, EventArgs e) {
            // Create a new chart.
            ChartControl stockChart = new ChartControl();

            // Create a stock series.
            Series series1 = new Series("Series 1", ViewType.Stock);

            // Specify the date-time argument scale type for the series,
            // as it is qualitative, by default.
            series1.ArgumentScaleType = ScaleType.DateTime;

            // Add points to it.
            series1.Points.Add(new SeriesPoint(new DateTime(2017, 3, 1),
