            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);
            IWorksheet sheet = workbook.Worksheets[0];

            //Add data
            sheet.Range["A1"].Text = "Jan";
            sheet.Range["B1"].Text = "Feb";
            sheet.Range["C1"].Text = "Mar";
            sheet.Range["A2"].Value = "10";
            sheet.Range["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";
            sheet.Range["A3"].Value = "15";
            sheet.Range["B3"].Value = "25";
            sheet.Range["C3"].Value = "35";

            //Create chart
            IChart chart = sheet.Charts.Add();

            //Set range
            chart.DataRange = sheet.Range["A1:C3"];

            //Set chart type
            chart.ChartType = ExcelChartType.Column_Clustered;

            //Get chart categories collection
            IChartCategories categories = chart.Categories;   

            //Get chart second category
            IChartCategory category = categories[1];           

            //Displaying the labels address of the category object
            Console.WriteLine("Category labels address is:" + category.CategoryLabel.AddressLocal);

            //Save and Dispose
            workbook.SaveAs("Chart.xlsx");
            workbook.Close();
            Console.ReadKey();
        }

IsFiltered

True if the user filters out category. otherwise False.

Declaration
bool IsFiltered { get; set; }
Property Value
Type Description
System.Boolean
Examples

By default all the categories in the chart are shown because this property is set to "false". Here for example, we filter out first category from the chart and it will not be shown in the chart.

        using (ExcelEngine excelEngine = new ExcelEngine())
        {
            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);
            IWorksheet sheet = workbook.Worksheets[0];

            //Add data
            sheet.Range["A1"].Text = "Jan";
            sheet.Range["B1"].Text = "Feb";
            sheet.Range["C1"].Text = "Mar";
            sheet.Range["A2"].Value = "10";
            sheet.Range["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";
            sheet.Range["A3"].Value = "15";
            sheet.Range["B3"].Value = "25";
            sheet.Range["C3"].Value = "35";

            //Create chart
            IChart chart = sheet.Charts.Add();

            //Set range
            chart.DataRange = sheet.Range["A1:C3"];

            //Set chart type
            chart.ChartType = ExcelChartType.Column_Clustered;

            //Get chart categories collection
            IChartCategories categories = chart.Categories;

            //Get chart first category 
            IChartCategory category = categories[0];

            //Filter out the first category
            category.IsFiltered = true;

            //Save and Dispose
            workbook.SaveAs("Chart.xlsx");
