If you know the basics of python or R, doing a multiple histogram is much easier than in Excel. You can finish your graph adding axis labels and graph titles and you're done.

Once you've done on the three series, you should end here: Final plot

Now select the fill bucket icon and click on each series to change fillto solid, choose colour and set transparency to 25%.

You should be here Second try Playing with overlapping % may give some interesting alternatives too. Select an overlapping of 100% and a bin width of 25%.

Now right click over any of the series in graph and select format the series.

To do that, right click on any one of them and select Hide all buttons option. First thing I do is delete all pivot buttons.This first try is honestly a bit awful, but we can adjust it. We won't use the histogram, as Excel doesn't allow to do histograms from pivot tables, we'll use the bar plot. Select Insert while the cursor is on the pivot table. Once you have the frequency table, you can insert a graph.Go to the table and do a right click over any of the row values and select Group.In this case, I group from 170 to 240 by 5 Grouping in classes Pivot table grouped as frequency table You can easily regroup values by right clicking again over row value grouped classes and change grouping criteria.In Values field configuration option (the small down arrow at right), select Count to get the frequency of values Pivot table field selection Put in columns the variable that's going to be the class, we'll use species.

Put in rows and values the variable you want to do the histogram in this case, using penguinsdataset, we will use flipper_length_mm.

From your data table, insert pivot table as new sheet Data table.

To use Excel, try the pivot table option. I will use the penguins dataset as example, as I don't have access to your data. Anyway, for the sake of answering, I offer my solution. I know it's an old one, surely you've found a solution time ago. I just dropped by here and saw your question today.
