3 mins read

Syncfusion® Essential® DocIO is a .NET Core Word library used to create, read, and edit Word documents programmatically without Microsoft Word or Interop dependencies. Using this library, you can create a stock open-high-low-close chart in a Word document in C#.

What is an open-high-low-close chart?

An open-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.

Open-High-Low-Close chart in Word document

Steps to create an open-high-low-close chart in a Word document:

Step 1: Initialize chart

Create a chart object by calling the paragraph.AppendChart(446, 270) method.

//Create and append the chart to the paragraph.
WChart chart = paragraph.AppendChart(446, 270);

Step 2: Assign data, chart type, and chart elements

Add the basic elements like the chart title, data labels, legend, and specify the chart type to the OfficeChartType.Stock_OpenHighLowClose enum value.

Assign data.
Chart type.
Data labels via DefaultDataPoint
Chart title of the chart object.
Set TRUE to the chart’s HasLegend property to show the legend; else FALSE.

//Set region of chart data.
chart.DataRange = chart.ChartData[1, 1, 5, 6];
 
//Set chart type.
chart.ChartType = OfficeChartType.Stock_OpenHighLowClose;
 
//Set a chart title.
chart.ChartTitle = "Open-High-Low-Close Surface Chart";
 
//Set legend.
chart.HasLegend = true;
chart.Legend.Position = OfficeLegendPosition.Bottom;
 
//Set data labels.
series1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
series1.DataPoints.DefaultDataPoint.DataLabels.IsSeriesName = true;
series1.SerieFormat.MarkerStyle = OfficeChartMarkerType.Circle;
series1.SerieFormat.MarkerBackgroundColorIndex = OfficeKnownColors.LightGreen;
series1.SerieFormat.MarkerForegroundColorIndex = OfficeKnownColors.Black;

Note:

For creating a stock open-high-low-close chart, the series count must be 4. The data range should be set before selecting the chart type.

Properties used to modify the markers in an open-high-low-close chart

Below is a list of properties that are used to change the markers in an open-high-low-close chart:

MarkerBackgroundColor (or) MarkerBackgroundColorIndex
MarkerForegroundColor (or) MarkerForegroundColorIndex
MarkerSize
MarkerStyle
IsAutoMarker
Note:
1. Marker properties are applicable for all open (chart.Series[0]), high (chart.Series[1]), low (chart.Series[2]), and close (chart.Series[3]) series.
2. If the close value (chart.Series[3]) is greater than the open value (chart.Series[0]), then those are called Up-Bars, and the FirstDropBar property can be used to format them using DocIO.
3. If the close value (chart.Series[3]) is less than the open value (chart.Series[0]), then those are called Down-Bars, and the SecondDropBar property can be used to format them using DocIO.

The following C# code sample shows the creation of a stock open-high-low-close chart using the Word library.

//Create a new Word document.
using (WordDocument document = new WordDocument())
{
    //Add a section to the document.
    IWSection section = document.AddSection();
    //Add a paragraph to the section.
    IWParagraph paragraph = section.AddParagraph();
    //Create and append the chart to the paragraph.
    WChart chart = paragraph.AppendChart(446, 270);
    //Set chart data.
    chart.ChartData.SetValue(1, 1, "Date");
    chart.ChartData.SetValue(2, 1, "Open");
    chart.ChartData.SetValue(3, 1, "High");
    chart.ChartData.SetValue(4, 1, "Low");
    chart.ChartData.SetValue(5, 1, "Close");
    chart.ChartData.SetValue(1, 2, "1-Apr-17");
