How to filter Excel chart series in C#, VB.NET?
This article explains how to filter series in a chart using WinForms XlsIO.
How to filter chart series?
Chart series are filtered using the IsFiltered property from the IChartSerie interface in XlsIO. This property controls whether to filter out series from the chart. The default value is `false`.
Chart series filtered using XlsIO
Code snippet to filter chart series
Filter chart series using IsFiltered property
// Filter chart series serie1.IsFiltered = 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 filter series in chart 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";
// Filter series
serie1.IsFiltered = 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);
}
}
}
}
