In a previous post I demonstrated how to create histograms using PivotTables.
For example, in our chart, it decided that there should be four bins. You can change this by using the ‘Bin Width/Number of Bins' options (covered below). Bin Width: Here you can define how big the bin should be. If I enter 20 here, it will create bins such as 36-56, 56-76, 76-96, 96-116. The bin width specifies how big the bin needs to be. Modifying the Bin Width. This will make the frequency of ages in a group increased by 2 at each iteration. Histogram with a Bin Width of 2. We can also change the number of bins of a histogram in excel. To make the histogram have 5 bins, we need to go to step 2 and set the. How can I change the number of bins for a histogram in excel for mac without putting in a bin range? This is doable in PC but I don't see it for Macs. This thread is locked.
- Select a beginning point that is lower than or equal to both the lower spec limit and the min value calculate bin intervals in Excel by taking the beginning value + the bin width, + the bin width, etc. Round the calculated values if desired select an ending point that is higher than or equal to both the upper spec limit and the max value.
- Mar 06, 2020 Histograms are supported by Excel 2019, 2016, 2013, 2010, 2007 and Excel for Mac, but the steps you take depend on which version of Excel you're using. The Analysis ToolPak add-in is required to use the histogram tool.
I like this tip so much that I recorded it as my favorite tip of the year for the MyExcelOnline podcast.
There is a shortcoming to this approach, however. By plotting a histogram in Excel using PivotTables, all bins must be of the same width. What if you wanted unequal bins?Excel provides a tool to make this kind of histogram, using an array formula.
(Note: For this exercise you don't really need to know much about array formulas, but they are worth checking out. I suggest Mike Girvin's book Ctrl+Shift+Enter: Mastering Excel Array Formulas to learn more.)
Let's get started. Download the exercise file here.
1. Mark your bins…
If you plot a histogram using either Excel's built-in charting or from a PivotTable/PivotChart, you must group the bins by equal increments (e.g. 1-5, 6-10, 11-15, etc.)
This might not work for your analysis, for different reasons. In our example, we know that the majority of our data falls between 1 and 10. So we want smaller-sized bins for this range and wider bins for the upper reaches of our data.
To set our own bins we will type in our desired increments. I put mine in column E of the exercise file.
This is a little confusing at first so I provide an interpretation of what these bins mean in Column D. Each bin ends at the stated value and starts from where the last bin left off.
Excel will automatically fill in any remaining values that don't fit into the last bin. This is cell F12 in our example. So cell E12 is just marked as helpful additional information.
2. Create a frequency table using the FREQUENCY array function

Next we will get a count of the frequencies of each bin in our data using the FREQUENCY function. Find usb serial number registry. This takes two arguments: our data array and our bin array.
Highlight where we want our frequency table to go (next to the bins) and fill out that formula just like you normally would.
Important! You probably press Enter after filling out most formulas in Excel. This time, press Control + Shift + Enter to complete the FREQUENCY function. That's because this function is calculating out over an array of cells rather than just one. (I won't go into it more than that, so please check out Mike Girvin's book above if you are interested. It's a great Excel skill to have.)
Now we have a frequency count of our bins.
3. Create a bar chart of our frequency table
Now to plot our histogram, we will go to Insert and select a bar graph.
Usually columns in a histogram are rather close to each other. To modify width between the bars, right-click on any of the bars. In the drop-down menu, select Format Data Series. Then reduce the Gap Width to a small amount.
This is a helpful tip because, as I mentioned, sometimes the logic of your data warrants unequal bins.
