You have been there before.
Trying to compare last year numbers with this year, or last quarter with this quarter.
Today, let us learn how to create an interactive to chart to understand then vs. now.
Demo of Then vs. Now interactive chart
First, take a look the completed chart below. This is what you will be creating.
Inspiration for this chart
Before we jump in to Excel and understand how this is done, let me thank NY Times for providing the inspiration for this chart. I saw a similar chart in their climbing income ladder visualization.
Creating Then vs. Now chart in Excel
1. Arrange data
As usual, the first step is to get the data in to Excel. Structure your data like this.
2. Insert a combo box control to select a region
Since our chart will display values for one region at a time, we need a mechanism to let user control which region is displayed. We will use a combo box control do this. Follow these steps.
- Go to developer ribbon and insert combo box form control.
- Right click on the combo box and go to format control.
- Set up input range to list of regions in your data.
- Set up cell link to a blank cell in your workbook.

3. Fetch selected region’s data
Now that we have a combo box to select which region to show in the chart, next step is to fetch data for selected region. You can use either VLOOKUP or INDEX formulas to do it.
Using VLOOKUP formula:
Assuming region name is in D17, and data is in values table, write:
=VLOOKUP(D17, values, 2, false)
to get 2nd column (then sales) value.
Using INDEX formula:
Assuming region number is in D16, and data is in values table, write:
=INDEX(values[then],D16)
4. Create a chart showing then to now movement
Next step is to create a chart that would show a line going from then value to now value. Lets take a closer look the line to understand how to make it in Excel.
We can create this chart with either XY (scatter) plot or line chart. Lets go with scatter plot.
In your workbook, set up a table like this:
Then, select the above and create a scatter plot. Select the scatter plot with connecting lines.
5. Formatting the chart
Since we want to show a thick circle at the beginning of then value and arrow at the end of now value, lets go ahead and do the formatting song and dance.
Formatting the first point:
- Select the first point of then values (you need to click once on it, take 3 deep breaths, click again and sacrifice a goat).
- Press CTRL+1 to format the data point.
- Go to Marker options and select built in marker and use the circle symbol.
Formatting the last point:
- Select the last point (same as above, but this time sacrifice a chicken)
- Format the data point.
- Go to line style, select End type and choose arrow.
Formatting the horizontal axis:
- Select horizontal (x) axis and press CTRL+1
- Set axis minimum to 1, maximum to 6.
- Click ok and delete the axis as we do not need it on the chart.
6. Adding “Break-up” of now values chart
This is easy, Just select fetched break-up values for selected region and create a bar chart. Format it as per your fancy.
7. Put everything together
Place the combo box, scatter plot and bar chart together in a nice fashion. Add a surrounding box shape so that everything looks like one report.
Add a descriptive title on the top. If possible, make chart title dynamic so that you can show the selected region name and % change in it.
8. Your Then vs. Now chart is ready
That is all. Your Then vs. Now chart is ready. Go ahead and flaunt it.

Do you make then vs. now charts?
I think about half the charts made businesses around the world fall in to this category. I make these type of charts all the time. I use a variety of chart types to convey this information. Thermometer chart, waterfall chart and conditionally formatted tables are some of my favorite techniques.
What about you? Do you create then vs. now charts? what type of charts do you use? Please share your techniques and ideas using comments.

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.
