Contains settings used to display up-down bars on a 2-D line or stock chart.
Use the ChartView.UpDownBars property to access an object exposing the UpDownBarsOptions interface.
Up-down bars on a two-dimensional line chart are used to emphasize the difference between data points in the first and last series in the data series collection, as shown in the image below (the chart is displayed in Microsoft® Excel®). To display up-down bars on a 2-D line chart, set the UpDownBarsOptions.Visible property to true. Note that if you try to display up-down bars on a chart that does not support them, an exception occurs.
The Open-High-Low-Close and Volume-Open-High-Low-Close stock charts display up-down bars by default. The bottom and top borders of a bar represent the Open and Close prices, respectively. By default, if the stock closes higher than its opening price, the hollow up bar is displayed. And if the stock closes lower than its opening price, the filled down bar is shown.
To specify format options to be applied to up-down bars, use the UpDownBarsOptions.UpBars and UpDownBarsOptions.DownBars properties. To set the space between up-down bars on a chart, utilize the UpDownBarsOptions.GapWidth property.
Currently, the SpeadsheetControl does not display up-down bars on a line chart and does not allow changing the bar properties on a stock chart. However, display settings are loaded and stored in supported formats, so that you can modify them programmatically and display the result in Microsoft® Excel®.
