Object Type	Path to UnderflowValue
SeriesLayoutOptions	.Histogram .UnderflowValue

Remarks

Set the HistogramSeriesOptions.UnderflowType property to Fixed and use the UnderflowValue property to create the underflow bin for all points that are below or equal to the specified value.

The following example demonstrates how to create a histogram chart and display the underflow bin:

C#

// Create a histogram chart and specify its location.
Chart chart = worksheet.Charts.Add(ChartType.Histogram, worksheet["B2:B21"]);
chart.TopLeftCell = worksheet.Cells["D2"];
chart.BottomRightCell = worksheet.Cells["K18"];

// Specify histogram series options.
var options = chart.Series[0].LayoutOptions.Histogram;
options.BinType = HistogramBinType.BinWidth;
options.BinWidth = 20;
// Create the underflow bin for all values
// that are below or equal to 50.
options.UnderflowType = HistogramOverflowType.Fixed;
options.UnderflowValue = 50;

// Specify the gap width.
chart.Series[0].GapWidth = 10;

// Add the chart title.
chart.Title.Visible = true;
chart.Title.SetValue("Exam Score Distribution");

VB.NET

' Create a histogram chart and specify its location.
Dim chart As Chart = worksheet.Charts.Add(ChartType.Histogram, worksheet("B2:B21"))
chart.TopLeftCell = worksheet.Cells("D2")
chart.BottomRightCell = worksheet.Cells("K18")

' Specify histogram series options.
Dim options As HistogramSeriesOptions = chart.Series(0).LayoutOptions.Histogram
options.BinType = HistogramBinType.BinWidth
options.BinWidth = 20
' Create the underflow bin for all values
' that are below or equal to 50.
options.UnderflowType = HistogramOverflowType.Fixed
options.UnderflowValue = 50

' Specify the gap width.
chart.Series(0).GapWidth = 10

' Add the chart title.
chart.Title.Visible = True
chart.Title.SetValue("Exam Score Distribution")
