Whenever we deal with large amounts of data, one of the goals for analysis is,
How is this data distributed?
This is where a Box plot can help. According to Wikipedia, a box plot is a convenient way of graphically depicting groups of numerical data through their five-number summaries: the smallest observation (sample minimum), lower quartile (Q1), median (Q2), upper quartile (Q3), and largest observation (sample maximum) [more]
Quartile?!? What is that like?
When we say $ 39,000 is the lower quartile of salaries paid in Acme inc. it means, 25% of people make less than or equal to $39,000
Like that Median (Q2) means half the samples are lower than median & the other are more than median.
Example Box Plot
Here is an example box plot depicting salaries of all analysts in USA as per our recent Excel Salary Survey.
The box shows distribution of middle half of data (salaries) while the lines (called as whiskers) show minimum and maximum salaries.
As you can see, 50% of the analysts make between $46,000 to $75,000 while the min is $10k and max is $160k.
Why use Box plots?
Box & whisker plots are an excellent way to show distribution of your data without plotting all the values. They are easy to understand. We can use them whenever we have lots of data or dealing with samples drawn from larger population.
Creating Box plots in Excel – 9 step tutorial
Despite their utility, Excel has no built-in option to make a box plot. Of course you can make a 3D pie chart or stacked horizontal pyramid chart. Lets save them for your last day at work and understand how to create box plots in Excel.
Step 1: Calculate the number summaries
Assuming your data is in list use formulas MIN, MAX & PERCENTILE to calculate summaries like below:
To calculate 25th percentile (Q1) use = PERCENTILE(list, 25%)
Step 2: Make a bar chart from Q1, Median & Q3
Just select the 25th percentile, median & 75th percentile values and create a bar chart.Make sure that your chart shows 3 different colored bars not 3 bars in one color.
Step 3: Set series overlap to 100%
Select any bar, press CTRL+1 (right click > format series) and adjust series overlap to 100%
Step 4: Adjust series order so that you can see all the bars
If you cannot see all the bars, right click on chart, click on “Select data”.
Now, adjust the series order using arrow keys so that you can see all the bars. See this demo:
Step 5: Make 25th percentile (Q1) bar invisible
Select the bar corresponding to Q1 and fill it with white color. If you make it transparent, it will not work. So make it all white.
Step 6: Add error bars to Q1 & Q3 series
Just select Q1 (25th percentile) bar and add error bar (any type) from layout ribbon.
Repeat for Q3 series as well.
Step 7: Set up error values in your data
Add an extra column in your data area and use simple formulas to calculate error values, like below:
Step 8: Set up custom error values for Q1 & Q3
Select the error bar for Q1 (25th percentile) and,
- Press CTRL+1 to format them
- Enable only minus (negative) error bar with no cap.
- Select Custom as error amount and point to the calculated value.
Repeat for Q3, but choose positive error bar instead.
Step 9: Format the box plot to your taste
Remove any legend, axis, labels that you do not need. Change colors to suit your taste and mood. Make the whiskers subtle and knock off the grid lines. You are good to go.
Making Box plots interactive
Since box plots are very useful to understand distribution of values, we use them in dashboards etc. Naturally, you are interested to know how values are distributed for various things.
In this example, we may want to know how analyst salaries compare with manager salaries.
To make things complicated, we have 10 different job types, thus enabling 45 possible comparisons (10c2)
This is where interactive box plots can help. See this demo to understand:
Interactive Box plot in Excel – a Demo
How to make interactive box plot in Excel
Construction of box plot is same as mentioned above. The difference is in adding interactivity.
Step 1: Use combo box form controls to capture comparison criteria
Excuse the tongue twister. Using Developer ribbon > Insert > Form controls, add 2 combo box controls and point them to the list of job types.
Lets assume that these combo boxes are linked to cells D1, D2.
[Related: Introduction to Excel Form Controls]
Step 2: Calculate 5 number summaries using MINIF, MAXIF and PERCENTILEIF formulas
Don’t rush to type the formulas yet. There is no such formula as MINIF (or MAXIF or PERCENTILEIF). Assuming your list of jobs are in joblist, write
=MIN(IF(joblist=”Analyst”, list_of_values,””))
and press CTRL+Shift+Enter
Using MAX(IF(…)) and PERCENTILE(IF(…)) you can calculate remaining 4 summaries.
Step 3: Based on combo box selection, fetch any two sets of values
Using INDEX formula, we can fetch values corresponding to each combo box selection to a set of cells, like this:
Step 4: Connect these values to your box plots
That simple!
Step 5: Format and interact
Format the charts. Play with combo boxes to interactively compare one set of distribution with another. Show it to your boss or client and see them fall off a chair.

Do you use Box plots?
I love box plots. I have used them several times. Few examples are here: Excel age survey results, Gantt box chart and more.
In our Excel salary survey contest too, many people have used box plots to clearly compare compensation composition. Checkout the entries by Aditya, Allred, Anchalee, Anup, Bryan, Jeanmarc, Joerg, Kostas, Luke, Michael, Nathan, Sergey and Vishwanath. Especially Jeanmarc used interactive version of box plots to allow comparison on demand.
What about you? Do you use Box plots often? How do you prepare them? What is your experience like? Please share using comments.

39 Responses to “11 very useful excel keyboard shortcuts you may not know”
You asked about a favorite keyboard shortcut: I often right click the navigation arrows at the bottom of an Excel workbook to get a list of the worksheets. I can click the one I want without having to scroll left or right.
I regularly use the networkdays(x,y,z) function to show the number of working days between two given dates. To exclude public holidays I reference a list of dates ("z" in the above reference) which I periodically update to reflect upcoming non-working days. To keep the sheet looking tidy for other users, I like to hide this column when I'm done, and then unhide it when I update the sheet.
With 40 separate workbooks to edit, these shortcuts make it a breeze...
? Hide selected column: CTRL+0 [zero]
? Unhide hidden column(s) within selection: CTRL+SHIFT+) [closed parenthesis]
If an "Autofit Selection" keyboard shortcut (not just a key sequence) existed, I'd be as happy as a clam!
you can use Alt+o+c+a to autofit selection
Is there a way to auto arrange the column width as you enter the data. Without a macro
You may use alternative key of hide the selected cell by ---print + H key
Unhide---prnt+U keys

Hello Chandoo, thanks for sharing this information. With some of the shortcuts I seem to have difficulties as they do not seem to work on the German keyboard.
Can you maybe verify that those combos are only working with the keyboard setup you are using? What would be a good source to lookup combinations for other layouts?
Regards, 1xoid1
@1xoid1 ... Thanks for visiting PHD and taking timeout to ask your question. Unfortunately all my German can be summarized to one phrase: "guten tag".
I wont be able to help you, but I can request other readers to respond. So if you know German or use German keyboard and can answer 1xoid1's question, then you get a free donut.
Guten Tag 🙂
To Sam Krysiak.
Shortcut to Autofit Selection (assuming you mean autofit columns). If you right click toolbar, click customise. From Commands tab/Categories select Built-in Menus.
In Categories window scroll down and select Columns and drag drop it onto toolbar. Then click the new toolbar Columns button and drag drop Autofit button onto your toolbar (note Autofit for Columns will no longer appear in your menus, only on toolbar).
Remove Columns button from toolbar (if you want to keep clutter down) drag and drop it off of your toolbar.
Close Customise box.
Now to Autofit columns just press "Alt" then "A".

@1xoid1:
Read the following text as follows: The key ,[;] is the one right to the M on the German keyboard. Here are the differences you have to know when using a German keyboard:
2. Press strg .[:] for inserting the current date (and strg shift .[:] for inserting current time)
3. Press strg ,[;] to copy values from cell above
8. Press strg shift –[_] to apply an outline border
10. Press strg-shift S to activate the font drop down (Schriftgroesse)
11. Press strg-shift G to activate the font size (Groesse)
Number 10 and 11 do not work with Excel 2007 anymore, but strg-shift-P shows the font tab of the cell format dialogue in Excel 2007.
All other shortcuts should work on a German keyboard exactly as Chandoo described them.

@Prashant... You can use conditional formatting to highlight duplicate entries in the three columns. That way whenever you type a dupe value in a cell the formatting would highlight the values so that you can avoid the error.

3. Magic.... 🙂
F3 = Paste a Name or the entire list of Names

Great article with some very useful follow-up comments and tips.
One simple question … how do you vertically align the drop-down filter button in a cell with a larger than normal height?
It’s easy enough to do so with a cell’s contents but the drop-down filter button stubbornly remains at the bottom and I need it at the top!
I’ve looked everywhere and haven’t located an explanation to what I am sure is considered an Excel basic.
Cheers
