Remarks
The example below creates a histogram with a custom bin size. Set the BinType option to HistogramBinType.BinWidth and use the HistogramSeriesOptions.BinWidth property to define the desired width for histogram bins.
// 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 = 24;
// Specify the gap width.
chart.Series[0].GapWidth = 10;
// Add the chart title.
chart.Title.Visible = true;
chart.Title.SetValue("Exam Score Distribution");
