My friend Paresh writes excellent commentary on charts on his blog Visual Quest. Last week he gave a home work, asking his readers to recreate the small multiples chart shown below.
I found this quite interesting. Small multiples, also called as panel charts, are a powerful way to depict multidimensional data and bring out insights. They are easy to read too.
So, today, let us learn how to create such charts using Excel.
Step 1: Arrange your data
Almost any chart or visualization worth its salt must begin with proper arrangement of data. Since I could not get the data for the unemployment chart, I made up a few numbers for a fictional Confectionery Company. The data is shown below.
So, we have the data for years 2007 thru 2010, for the regions – South, West & North and for the product lines – Chocolates & Biscuits
Step 2: Select Products for one region & make an area chart
This is simple. Just select data for chocolates & biscuits for one region and make an area chart. You should have something like this:
Step 3: Resize the area chart & format it
Now, we need to make this area chart closer to what we want.
- Select the bottom area series and fill it with white color.
- Now resize the chart so that we can fit 3 of them in the area you got.
Step 4: Add same data to the chart
Now, select the same region data, press CTRL+C to copy it. Select the chart and paste it by pressing CTRL+V. See below demo to understand how to do this.
We are doing this because we want to have lines with markers on our chart. But the area chart lines cannot show markers. So we are going to add the same data one more time, but this time format it to be shown as a line.
Step 5: Select the new series and format them as line charts
Select each of the new area series and format as line chart with markers.
You should have something like this at the end.
Step 6: Format the chart
This is where you unleash the creativity. In order to match the look of NYTimes chart, here is what you can do.
- Set the fill color between lines to something dull.
- Format 2 lines in distinct colors.
- Format gridlines & axis lines to something dull.
- Set axis maximum to 25 (as all charts in small-multiples should have same axis settings)
- Set axis major unit to 5.
Step 7: Repeat this for other regions
Now, just copy and paste this chart a couple of times. Just adjust the data source so that we have new charts using this technique.
Note: Learn how you can add descriptive labels to charts.
That is all. You just made a small multiples chart that looks awesome. Congratulations.

Do you use Small Multiples or Panel Charts?
I really love to use small multiples or panel charts whenever I am analyzing data or presenting results of the same. They offer excellent value per pixel. That said, they take some time to construct. Also, you must tweak axis settings and plot area to get the perfect result. That is why I prefer the in-cell variation of these charts. They are quick to setup and easy to wow (for more on these techniques, see below).
What about you? Do you use Small Multiples or Panel charts? How do you find them? Please share using comments.

As you can guess, small multiples is one of my favorite ways to explore and present data. So we have written quite a few articles explaining this technique. Read these to learn more.

Some great contributions here.
Gotta love the Friday 13th formula 😀
Great tips from you all! Thanks a lot for sharing! bsamson, particularly you helped me on a terribly annoying task. 🙂
(BTW, Chandoo, it's not exactly "Find if a range is normally distributed" what my suggestion does. It checks if two proportions are statistically different. I probably gave you a bad explanation on twitter, but it'd be probably better if you fix it here... 🙂 )
Great compilation Chandoo
For the "Clean your text before you lookup"
=VLOOKUP(CLEAN(TRIM(E20)),F5:G18,2,0)
I would like to share a method to convert a number-stored-as-text before you lookup:
=VLOOKUP(E20+0,F5:G18,2,0)
@Peder, yeah, I loved that formula
@Aires: Sorry, I misunderstood your formula. Corrected the heading now.
@John.. that is a cool tip.
Hey Chandoo,
That p-value formula is really great for a statistics person like me.
What a p-value essentially is, is the probability that the results obtained from a statistical test aren't valid. So for example, if my p value is .05, there's a 5% probability that my results are wrong.
You can play with this if you install the Data Analysis Toolpak (which will perform some statistical tests for you AND provide the P Value.)
Let's say for example I've got two weeks of data (separated into columns) with the number of hours worked per day. I want to find out if the total number of hours I worked in week two were really all the different than week one.
Week1 Week2
10 11
12 9
9 10
7 8
5 8
Go to Data > Data Analysis > T-Test Assuming Unequal Variances > OK
In the Variable 1 Box, select the range of data for week 1.
In the Variable 2 Box, select the range of data for week 2.
Check "Labels"
In the Alpha box, select a value (in percentage terms) for how tolerant you are of error.
.05 is the general standard; that is to say I am willing to accept a 95% level of confidence that my result is accuarate.
Select a range output.
Excel calculates a number of results: Average (mean) for each week's data, etc.
You'll notice however that there are two P Values; one-tail and two-tail. (one tail tests are for > or .05), the number of hours I worked in week two is statistically equivalent to the number of hours I worked in week one.
So here’s a way you might want to use this. You put up a new entry on your blog. You think it’s the best entry ever! So you pull your webstats for this week and compare it to last week. You gather data for each week on the length of time a visitor spends on your website. The question you’re trying to prove statistically is whether there’s an average increase in the amount of time spent on your website this week as compared to last week (as a result of your fancy new blog post). You can run the same statistical test I illustrated above to find out. Incidentally, it matters very little to the stat test whether the quantity of visitors differs or not.
Anyhow, the Data Analysis toolpack doesn't perform a lot of stat tests that folks like me would like to have access to. In those cases I have to either use different software, or write some very complicated mathematical formulas. Having this p-value formula makes my life a LOT easier!
Thanks!

Fantastic stuf..One line explanation is cool.
Thanks to all the contributors
OS
Take FirstName, MI, LastName in access (you can fix it to work in excel) capitalize first letter of each and lowercase the rest and add ". " if MI exists then same for last name:
Full Name: Format(Left([FirstName],1),">") & Format(Right([FirstName]),Len([FirstName])-1),"") & ". ","") & Format(Left([LastName],1),">") & Format(Right([LastName],Len([LastName])-1),"<")
I teach excel, access, etc etc for a living and i have my access students build this formula one step at a time from the inside out to show how formulas can be made even if it looks complicated. Yes I know I could just do IsNull([MI]) and reverse the order in the Iif() function but the point here is to nest as many functions as possible one by one (also I illustrate how it will fail without the Not() as it is)
Extract the month from a date
The easiest formula for this is =MONTH(a1)
It will return a 1 for January, 2 for February etc.
if in a column we write the value of total person for eg. 10 if we spent 1.33 paise each person then how we get total amount in next column and the result will in round form plzzzzz solve my problem sir................... thank u
@Anjali
If the value 10 is in B2 and 1.33 paise is in C2 the formula in D2 could be =B2*C2
If the values are a column of values you can copy the formula down by copy/paste or drag the small black handle at the bottom right corner of cell D2
kindly share with me new forumulas.
