How to set vertical axis crosses value for chart axis in C#, VB.NET?
This article explains how to set vertical axis crosses value for chart axis using WinForms XlsIO.
How to set vertical axis crosses value?
In an Excel chart, the horizontal (category) axis can be made to cross the vertical (value) axis using Horizontal axis crosses. Similarly, the vertical (value) axis can also be made to cross the horizontal axis using Vertical axis crosses. This can be achieved in XlsIO using CrossesAt property.
Code snippet to set vertical axis crosses value
Set the primary value axis (vertical axis) crosses value using CrossesAt.
//Set cross value chart.PrimaryValueAxis.CrossesAt = 3.5;
The category axis can be made to cross the value axis at maximum axis value by enabling IsMaxCross property.
//Set maximum cross chart.PrimaryValueAxis.IsMaxCross = true;
To know more about creating charts with various settings using XlsIO, please refer the documentation.
The following C#/ VB.NET complete code snippet shows how to set vertical axis crosses value using XlsIO.
C#
using Syncfusion.XlsIO;
using System.Reflection;
using System.IO;
namespace ChartSample
{
class Program
{
static void Main(string[] args)
{
using (ExcelEngine excelEngine = new ExcelEngine())
{
IApplication application = excelEngine.Excel;
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
IChartShape chart = worksheet.Charts.Add();
chart.ChartType = ExcelChartType.Column_Clustered;
//Assign data
chart.DataRange = worksheet["A1:D6"];
chart.IsSeriesInRows = false;
//Apply chart elements
//Set chart title
chart.ChartTitle = "Clustered Column Chart";
//Set cross value
chart.PrimaryValueAxis.CrossesAt = 3.5;
//Set data labels
IChartSerie serie1 = chart.Series[0];
IChartSerie serie2 = chart.Series[1];
IChartSerie serie3 = chart.Series[2];
serie1.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie2.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
serie3.DataPoints.DefaultDataPoint.DataLabels.IsValue = true;
//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);
}
}
}
}
