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.

15 Responses to “Compare 2 Lists Visually and Highlight Matches”
Hi,
I solved this in a little different way.
We have 2 lists, one starts at A1 and other at B1, both are vertical arrays.
First thing is define 2 named ranges, list1 and list2:
list1 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$A$1:$A$1000""));1)"
list2 refers to "=OFFSET(Sheet1!$A$1;0;0;SUMPRODUCT(--(Sheet1!$B$1:$B$1000""));1)"
this way lists will be dynamically sized when you had or remove elements (you can't have blanks and you can't have more than 1000 elements).
Then I use conditional formatting in column A when this formula is true:
"=NOT(ISERROR(MATCH(A1;list2;0)))"
and "=NOT(ISERROR(MATCH(B1;list1;0)))" to list2.
This way we eliminate the need for auxiliary columns or lists.
Hope you like my way! 😀

Simple conditional formatting formula.
Assuming lists vertical lists starting in A1 & B1
To highlight just one column (assume B for example)
Conditional formatting>New Rule>by formula
=MATCH(B1,$A$1:$A$99,0)
Set the cell fill to what ever color you prefer & press OK
To highlight both columns repeat with this formula for cell in column A
=MATCH(A1,$B$1:$B$99,0)
This approach doesn't require named fields or addtl columns

Say I had 1 list in A2:A20 and another in B2:B20.
To format all the items in column A that are repeated in column B I would use the following Conditional Formatting rule.
=IF(ISNA(VLOOKUP(A2,$B$2:$B$20,1,false)),true,false)
All the duplicates are highlighted. It us a very simple example of comparison.
I may be missing something here, but I usually highlight both my lists by holding ctrl eg A1:A20 E10:E40 then choose conditional formatting from the ribbon and then highlight duplicates, and this does it?
Lee, I was perplexed as well. I do the same thing you do with the conditional formating. A drag and click to highlight range and choose highlight duplicates does the trick for me.
I believe these methods are to check if an item from one list also appears in the other list. So if an item mentioned many times in one list if also mentioned in the other list or not.
The Conditional Formatting highlight duplicates feature will do this, but it will also highlight an item if it appears multiple times in the one column or list.
Hi, I would just like to know (if you are willing to share) which image editing program you use to make your image like above, like they are torn apart from bottom? I've been looking for long.
@i48998
Chandoo is on Holidays, but Chandoo uses Paint.Net
Paint.net is a free download available at http://www.paint.net/
.
I use CorelDraw/PhotoPaint
.
We both use the Snipping Tool (a freebe with Win Vista/10)
.
We both use Camtasia for doing screen captures to make animated GIFs where you see animation.
Here is how I would accomplish
(1) Define Names: List_1, List_2
(2) =ISNA(MATCH(D4,List_2,0))-1 (Conditional Format formula List_1)
(3) =ISNA(MATCH(D4,List_1,0))-1 (Conditional Format formula List_2)
ISNA will return 1 if NO Match and O if Match by adding a -1 will make: NO Match 0 and Match a -1 which is True
Hi all
this my first Post here
i think we can take Unique List for tow list to know what is not Duplicate By this Array formula
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISERROR(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
and this one for Duplicate Value
=IFERROR(INDEX($D$6:$D$33,SMALL(IF(ISNUMBER(MATCH($D$6:$D$33,$B$6:$B$33,0)),ROW($D$6:$D$33)-ROW($D$6)+1),ROWS($J$5:J5))),"")
Don't forget to Enter This Formula by Pressing Ctrl+Shift+Enter
without wanting to ruthlessly self promote here, I do have an addin that does neatly compare two ranges, not just in columns, so you might want to check that out.
Having said that this is a pretty neat solution if you dont want to be going down the VBA or purchase route. I like it
however, could you not do something with the remove duplicates feature in Excel 2010 and then compare the resulting data set?
Hi, Chandoo! I've found yesterday your Excel website... What can I say? It's just awesome, Excellent. Being a developer for 30 years, more than 15 with Office products, and wow!, how many things I discovered in a couple of hours, and what pretty resolved.
I decided to take the long path of the newbies and read all your examples and write down by myself all of them, and when I arrived to this (the comparison of two lists) I think I've found a problem:
a) in "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)" it should say "Step 4: Apply conditional formatting to Second List - Use the same logic, but this time the rule becomes =COUNTIF(count1s,$H6)>0", but this is a typing error that I believe all of us here might have discovered and corrected
b) the very problem: I wrote down two different lists, in different ranges, and with different number of elements, I specified the equivalent conditional formats, et non voilá!, I didn't get what expected. So I downloaded your example book, I checked range names, formulaes, conditional formats and all OK. So I copied -just values- from my book to yours, and I still couldn't achieve the goal.
I'm using Excel 2010 in spanish, I'm from Buenos Aires (Argentina), and my book is at your disposition whenever you considerate it appropiate.
Thanks in advance for your time, and again my congratulations for your work here.
Best regards.

Comparison of 2 lists visually with highlights
Author: SirJB7 / Date: 11-Dic-2011
Pros: no duplicated tables, no matrix formulaes, no named ranges, no VBA code, just conditional formatting
Cons: not found yet, comments and observations welcome
Features:
a) standard problem: highlights in orange/yellow elements existing in the other list
b) optimized problem: idem a) plus highlights in red/violet first occurrence of elements existing in the other list
Sheet contents:
a) conditional format, 1 rule per list (2 methods used)
A1:A20, first list
B1:B20, second list
a1) range A1:A20, condition =NO(ESERROR(BUSCARV(A1;B$1:B$20;1;FALSO))), format Orange ---> in english: =NOT(ISERROR(VLOOKUP(A1,B$1:B$20,1,FALSE)))
a2) range B1:B20, condition =CONTAR.SI(A$1:A$20;B1)>0, format Yellow ---> in english: =COUNTIF(A$1:A$20,B1)>0
b) conditional format, 2 rules per list (2 methods used)
D1:D20, first list
E1:E20, second list
b1) range E1:E20, condition 1 =Y(NO(ESERROR(BUSCARV(D1;E$1:E$20;1;FALSO)));COINCIDIR(D1;D$1:D$20;0)=FILA(D1)), format Red ---> in english: =AND(NOT(ISERROR(VLOOKUP(D1,E$1:E$20,1,FALSE))),MATCH(D1,D$1:D$20,0)=ROW(D1))
same range, condition 2 and format 2, same as a1)
b2) range E1:E20, condition =Y(CONTAR.SI(D$1:D$20;E1)>0;COINCIDIR(E1;E$1:E$20;0)=FILA(E1)), format Violet ---> in english: =AND(COUNTIF(D$1:D$20,E1)>0,MATCH(E1,E$1:E$20,0)=ROW(E1))
same range, condition 2 and format 2, same as a2)
Personally I like the a2) and b2) solutions, I think the formulaes are prettier.
I still don't know the rules of this website and forum, but it any precept is infringed I'm willing to share the workbook with the solution. If it breaks a rule, I apologize and promise that won't happen again.
Best regards for all!
Dear All i have a complicated situation...
1. I have two sheets of data Sheet1 and Sheet2 (from various sources) - Both of these contain data matching and Not matching as well..
2. Now for me i need to build an excel where in i need to get sheet 3 with values that are present in a column of Sheet 1.
What ever Sheet 1 doesn't have i dont want those rows from sheet 2 to be populated into Sheet3.
Can any one help me out.
Hi Team
The above example is to compare partial name from 2 different columns.
If I want to cross check it in a single column. I have both correct and partial correct/match entries in a column. Is there any way I can find both the entries in the column.
Regards
