# HiLo Charts ## Content A **HiLo** chart combines two independent values to supply high and low data for each point in a series. HiLo charts are used primarily in financial applications to show the high and low price for a given stock. The elements of the Y and Y1 arrays in each series of a HiLo chart represent the "high" value, and the "low" value. Using the [LineStyle](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartDataSeries.LineStyle.html), the fill and line properties of each series can be customized. For more information, see [Line and Symbol Styles for the Series](/componentone/docs/win/online-chart2d/customizingchartelem/lineandsymbolstylesf).

Open the **ChartGroups Collection Editor** by clicking the **ellipsis** button. In the right pane of the editor, set the [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) property to **HiLo**. * An alternate method to change chart type is to right-click the existing chart and select **Chart Properties**. From the Gallery, select [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) as Stock and Chart sub-type as Hi-low. * Another alternate method is to select **Chart Properties** from the Properties pane. From the Gallery, select [ChartType](/componentone/api/win/online-chart2d/dotnet-framework-api/C1.Win.C1Chart.4.8/C1.Win.C1Chart.ChartGroup.ChartType.html) as Stock and Chart sub-type as Hi-low. ## See Also [HiLo Chart Programming Considerations](/componentone/docs/win/online-chart2d/specific2dcharts/hilocharts/hilochartprogramming)
