Download Free Better Histogram Add-In for Excel

This free add-in shows just one of the important features of the upcoming Better Histogram add-in.

  • A histogram is usually shown in Excel as a Column chart type (vertical bars).
  • The labels of a Column chart are aligned under the center of each bar, and there is no Excel feature for changing the alignment.
  • For continuous-valued data, a better histogram has a horizontal axis with numerical labels aligned under the tick marks between the bars as shown below.

Before you use the Better Histogram add-in, you may want to use Excel’s MIN and MAX worksheet functions to determine the minimum and maximum values of your data values, so that you can decide on “nice” intervals for your histogram.

To use the Better Histogram add-in, select the Excel worksheet containing your data.

  • In Windows Excel 2010 & 2013 & 2016, choose Add-Ins ribbon > (Menu Commands section) Better Histogram, or press the shortcut key Control+Shift+B.
  • In Mac Excel 2011, choose Tools | Better Histogram, or press the shortcut key Option+Command+B.
  • In Mac Excel 2016, press the shortcut key Option+Command+B.

better-histogram-dialog

Inputs for the Better Histogram dialog box:

  • The data range must be a range of cells containing only numbers, i.e., no text.
  • The start value must be a number less than or equal to the minimum value of the data range.
  • The step value must be greater than zero.
  • The stop value must be greater than or equal to the maximum value of the data range.
  • The start, step, and stop values must be chosen so that there are at least two intervals.

When you click OK, the frequency distribution and Better Histogram are created on a new worksheet.

better-histogram-chart

You can use Excel features to modify the chart titles and to apply formatting as you wish.

If you want to modify the horizontal axis scale, it is important to align the values of the XY (Scatter) chart type with the vertical bars of the Column chart type.

 

The original manual method for creating a Better Histogram using Excel 2003 is described in detail in the paper Better-Histograms-Using-Excel-2003.PDF.

That manual method is automated by the Better Histogram XLAM add-in from the ZIP file available when you click the “Download Better Histogram ZIP File” button above.
