Properties

CrossesAt

Represents the point on the axis another axis crosses it.

Declaration

double CrossesAt { get; set; }

Property Value

Type
System.Double

Examples

The following code illustrates how to set CrossesAt for charts.

        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";

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

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

            //Set chart value axis
            IChartValueAxis valueAxis = chart.PrimaryValueAxis;

            //Set cross at
            valueAxis.CrossesAt = 15;

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

CrossValue

Represents the point on the axis another axis crosses it.

Declaration

double CrossValue { get; set; }

Property Value

Type
System.Double

Remarks

This property is obsolete. Please use CrossesAt instead of it

DisplayUnit

Returns or sets the unit label for the specified axis.

Declaration

ExcelChartDisplayUnit DisplayUnit { get; set; }

Property Value

Type
ExcelChartDisplayUnit

Examples

By default the value axis displays no unit labels since DisplayUnitLabel is set to None by default. Here for example, we set Hundreds to DisplayUnitLabel.

        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 = "10000";
            sheet.Range["B2"].Value = "20000";
            sheet.Range["C2"].Value = "30000";

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

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

            //Set chart value axis
            IChartValueAxis valueAxis = chart.PrimaryValueAxis;

            //Set display unit
            valueAxis.DisplayUnit = ExcelChartDisplayUnit.Hundreds;

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

DisplayUnitCustom

Represents custom unit to display.

Declaration

double DisplayUnitCustom { get; set; }

Property Value

Type
System.Double

Examples

The following code illustrates how to set custom units for charts.

        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["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 value axis
            IChartValueAxis valueAxis = chart.PrimaryValueAxis;

            //Set display unit
            valueAxis.DisplayUnit = ExcelChartDisplayUnit.Custom;

            //Set display unit
            valueAxis.DisplayUnitCustom = 5;

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

        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";

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

            //Set chart value axis
            IChartValueAxis valueAxis = chart.PrimaryValueAxis;

            //Set display unit
            valueAxis.DisplayUnit = ExcelChartDisplayUnit.Hundreds;

            //Set Display unit label
            IChartTextArea unitLabel = valueAxis.DisplayUnitLabel;

            //Set label color
            unitLabel.FrameFormat.Fill.ForeColorIndex = ExcelKnownColors.Pale_blue;

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

HasDisplayUnitLabel

True if the label is displayed on the specified axis.

Declaration

bool HasDisplayUnitLabel { get; set; }

Property Value

Type
System.Boolean

Examples

By default DisplayUnitLabel is set to None so display unit label will not be shown. Here for example, we set Hundreds to DisplayUnitLabel property so the display unit label will be visible.

        using (ExcelEngine excelEngine = new ExcelEngine())
        {
            //Create worksheet
