Syncfusion Essential XlsIO is a .NET Excel library used to create, read, and edit Excel documents. Using this library, you can also reverse the chart axis plot order. Steps to reverse chart axis order programmatically:Chart axis order can be reversed by setting ReversePlotOrder property of that particular axis to true. C# //Reverse chart axis order chart.PrimaryValueAxis.ReversePlotOrder = true; chart.PrimaryCategoryAxis.ReversePlotOrder = true;
Below is the list of some of the common properties that are used to format chart axis. The following C#/ VB.NET complete code snippet shows how to reverse chart axis order 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";
//Reverse chart axis order
chart.PrimaryValueAxis.ReversePlotOrder = true;
chart.PrimaryCategoryAxis.ReversePlotOrder = true;
//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);
}
}
}
}
