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 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 high-low-close chart:
Step 1: Initialize 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 chart’s DataRange property and specify the chart type to 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 chart title, data labels and legend.
- ChartTitle of chart object.
- Set DataLabels via DefaultDataPoint.
- Set TRUE to 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 Datalabels 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
