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.

Then vs. Now interactive chart - How to create this in Excel

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.

Data for Then vs. Now chart

2. Insert a combo box control to select a region

Insering combo box form control and formatting it - then vs now chartSince 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.

  1. Go to developer ribbon and insert combo box form control.
  2. Right click on the combo box and go to format control.
  3. Set up input range to list of regions in your data.
  4. 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.

More on using VLOOKUP formula

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.

Examining then vs now chart - a closer look at how to create it

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 vs. now values for selected region

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 starting point of then vs now chartFormatting the first point:

  1. Select the first point of then values (you need to click once on it, take 3 deep breaths, click again and sacrifice a goat).
  2. Press CTRL+1 to format the data point.
  3. Go to Marker options and select built in marker and use the circle symbol.

Formatting ending point - then vs. now chartFormatting the last point:

  1. Select the last point (same as above, but this time sacrifice a chicken)
  2. Format the data point.
  3. Go to line style, select End type and choose arrow.

Formatting horizontal axi - then vs now chartFormatting the horizontal axis:

  1. Select horizontal (x) axis and press CTRL+1
  2. Set axis minimum to 1, maximum to 6.
  3. 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.

Final Then vs. Now chart with all bells and whistles

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.

    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

  3. Alan says:

    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.

  4. Lee says:

    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?

  5. Greg says:

    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.

  6. Alan says:

    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.

  8. Hui... says:

    @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.

  9. Rick says:

    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

  10. 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

  11. Excel Addin says:

    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?

  12. SirJB7 says:

    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!

    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.

  15. Jagdev says:

    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
