Declaration

bool HasAutomaticBins { get; set; }

Property Value

Type
System.Boolean

Remarks

Examples

By default HasAutomaticBins is set to "false" so grouping will be done based on the categories in the IChartCategoryAxis. Here for example, we set HasAutomaticBins to "true" so that chart serie would be grouped automatically.

        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["B2"].Value = "20";
            sheet.Range["C2"].Value = "30";

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

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

            //Set range
            chart.DataRange = sheet.Range["A1:C2"];

            //Set chart category axis
            IChartCategoryAxis categoryAxis = chart.PrimaryCategoryAxis;

            //Set bins to automatic
            categoryAxis.HasAutomaticBins = true;

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

IsBetween

True to cut unused plot area. otherwise False. Default for area and surface charts.

Declaration

bool IsBetween { get; set; }

Property Value

Type
System.Boolean

Examples

By default IsBetween is set to "true" so chart serie will be plotted in between the tick marks. Here for example, we set IsBetween to "false" so that chart serie would be plotted on the tick marks.

        using (ExcelEngine excelEngine = new ExcelEngine())
        {
            //Create worksheet
            IApplication application = excelEngine.Excel;
            application.DefaultVersion = ExcelVersion.Excel2013;
            IWorkbook workbook = application.Workbooks.Create(1);

            //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";

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

            //Set range
            chart.DataRange = sheet.Range["A1:C2"];

            //Set chart category axis
            IChartCategoryAxis categoryAxis = chart.PrimaryCategoryAxis;

            //Set category axis IsBetween
            categoryAxis.IsBetween = false;

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

IsBinningByCategory

True if bins generated by category values. otherwise False

Declaration

bool IsBinningByCategory { get; set; }

Property Value

Type
System.Boolean

Remarks

Applies only to Histogram and Pareto charts.

Examples

By default IsBinningByCategory is set to "true" so chart serie are grouped based on category labels. Here for example, we set "false" to IsBinningByCategory so that chart serie would be grouped automatically.

        using (ExcelEngine excelEngine = new ExcelEngine())
        {
            //Create worksheet
            IApplication application = excelEngine.Excel;
