How to create Excel high low close chart in C#, VB.NET?
This article explains how to create a high-low-close chart in Excel using the Syncfusion® Excel (XlsIO) library.
What is a high-low-close chart?
A high-low-close chart is a type of chart typically used to illustrate movements in the price of a financial instrument over time. Each vertical line on the chart shows the price range over one unit of time.
High-Low-Close Chart
To create a high-low-close chart in Excel using XlsIO, you need to do the following steps.
Steps to create a high-low-close chart:
Step 1: Initialize the chart
Create a chart object by calling the worksheet.Charts.Add method.
C#
// Create the chart IChartShape chart = worksheet.Charts.Add();
Step 2: Assign data and specify the chart type
Set a range of data from the worksheet to the chart’s DataRange property and specify the chart type to the ExcelChartType.Stock_HighLowClose enum value.
C#
// Set region of Chart data chart.DataRange = worksheet["A1:F4"]; // Set chart type to Stock_HighLowClose chart.ChartType = ExcelChartType.Stock_HighLowClose;
For creating a stock high-low-close chart, the series count must be 3. The data range should be set before selecting the chart type.
Step 3: Apply basic chart elements
Add the basic elements like the chart title, data labels and legend.
- ChartTitle of the chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to the chart’s HasLegend property, to show the legend.
C#
// Apply chart elements // Set Chart Title chart.ChartTitle = "High-Low-Close Chart"; // Set Legend chart.HasLegend = true; chart.Legend.Position = ExcelLegendPosition.Bottom; // Set Data labels IChartSerie serie1 = chart.Series[0]; serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true; serie1.DataPoints.DefaultDataPoint.DataLabels.IsSeriesName = true; serie1.SerieFormat.MarkerStyle = ExcelChartMarkerType.Circle; serie1.SerieFormat.MarkerBackgroundColorIndex = ExcelKnownColors.LightGreen;
Properties used to modify the markers in the high-low-close chart
Below is the list of properties that are used to change the markers in high-low-close chart.
- MarkerBackgroundColor (or) MarkerBackgroundColorIndex
- MarkerForegroundColor (or) MarkerForegroungColorIndex
- MarkerSize
- MarkerStyle
- IsAutoMarkerNote:
Marker properties are applicable for all high (chart.Series[0]), low (chart.Series[1]) and close (chart.Series[2]) series.

The following C#/ VB.NET complete code snippet shows the creation of a high-low-close chart using XlsIO.
C#
using Syncfusion.XlsIO;
using System.Reflection;
using System.IO;

class Program
{
static void Main(string[] args)

application.DefaultVersion = ExcelVersion.Excel2016;
// Open existing workbook with data entered
Assembly assembly = typeof(Program).GetTypeInfo().Assembly;
Stream fileStream = assembly.GetManifestResourceStream("ChartSample.InputTemplate.xlsx");
IWorkbook workbook = application.Workbooks.Open(fileStream);
IWorksheet worksheet = workbook.Worksheets[0];
// Initialize chart and assign data
IChartShape chart = worksheet.Charts.Add();
chart.DataRange = worksheet["A1:F4"];
chart.ChartType = ExcelChartType.Stock_HighLowClose;
// Apply chart elements
// Set Chart Title
chart.ChartTitle = "High-Low-Close Chart";
// Set Legend
chart.HasLegend = true;
chart.Legend.Position = ExcelLegendPosition.Bottom;
// Set Data labels
IChartSerie serie1 = chart.Series[0];
IChartSerie serie2 = chart.Series[1];
IChartSerie serie3 = chart.Series[2];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie1.DataPoints.DefaultDataPoint.DataLabels.IsSeriesName = true;
serie1.SerieFormat.MarkerStyle = ExcelChartMarkerType.Circle;
serie1.SerieFormat.MarkerBackgroundColorIndex = ExcelKnownColors.LightGreen;
serie2.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie2.DataPoints.DefaultDataPoint.DataLabels.IsSeriesName = true;
serie2.SerieFormat.MarkerStyle = ExcelChartMarkerType.Circle;
serie2.SerieFormat.MarkerBackgroundColorIndex = ExcelKnownColors.Red;
serie3.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie3.DataPoints.DefaultDataPoint.DataLabels.IsSeriesName = true;
serie3.SerieFormat.MarkerStyle = ExcelChartMarkerType.Circle;
serie3.SerieFormat.MarkerBackgroundColorIndex = ExcelKnownColors.Light_yellow;
// Positioning the chart in the worksheet
chart.TopRow = 8;
chart.LeftColumn = 1;
chart.BottomRow = 23;
chart.RightColumn = 8;
// Saving the workbook
Stream stream = File.Create("Output.xlsx");
workbook.SaveAs(stream);
}
}
}
}
