Interview With Presentation Zen’s Garr Reynolds on Charting & Telling Stories

As mentioned earlier, I have met Garr Reynolds of presentation zen fame in Malmo, Sweden last Friday. What was to be a quick 15 minute interview became a 2 hour lengthy discussion on presentations, charting, excel, data, Japanese culture and of course our pointy haired dilbert blog. Garr liked my site alot that he tweeted about it immediately.

I am only posting portions of the interview here.

Q: Powerpoint and presentations are great way to communicate. But most of the time we deal with raw data and numbers. How to present such complex and diverse information without cluttering?

A: There are two types of people (1) the quantitative folks and (2) the design folks. For too long we had just these 2 types of people, one who can program, create great stuff and the other who are really good at designing fantastic things. But now, more than ever, the need is to combine both skills in one person.

One of things that I observe in my university MBA students (and most others too) is that, when it comes to presenting data (either through charts or tables), people go too fast. They just show one piece of information after another without spending time to discuss. Data doesn’t mean anything until we choose to talk about it.

I always recommend my students to have a lengthy Q&A where the facts are dissected and stories are brought out. We should always approach the charts (and data) with “yes this is what it is, but what does it mean? Anyone can make a chart, only intelligent can poke it”

Q: What are the raw (formatting) tips you can give to my readers? People always wonder about things like what color should I use, should I use grid lines or labels? Should I use several colors or shades of one color? Which font should I use?

A: Those are lot of questions [chuckles…]

My mantra is “maximum effect with minimum means”. That is what Tufte or Stephen Few says.

So, grid lines, often we don’t need those as they are implied. If you use them, I say use a very light color.

As far as choosing color, if it is a bright building or room, then a white background works. If it is a darker room we can use a black background.

Colors, as few as possible. These are the common mistakes that I see. I think using different shades of same color works well. You need to realize that lot of people are color blind, so it is safer to use shades of blue or gray than using lot of colors. There are really no hard and fast rules for colors. Don’t just spend too much time on the graph. Yes, it should be aesthetically pleasing, but the more important thing is you and what you want to say.

Q: Your opinion on dealing with situations where there is lot of data?

A: As you can see, most of my charts are very simple. But often we need to deal with lots of data. I am big fan of tables (as long as they are not too lengthy). I also recommend using handouts. If you have lots of data, it is better to take a printout or send the files so your audience can read the data, understand what it means and then you can have a discussion with them.

I recommend reading this article on NY Times about Steve Ballmer’s new meeting style where he says (quote inserted by Chandoo)

[Ballmer] … most meetings nowadays, you send me the materials and I read them in advance. And I can come in and say: “I’ve got the following four questions. Please don’t present the deck.” That lets us go, whether they’ve organized it that way or not, to the recommendation. And if I have questions about the long and winding road and the data and the supporting evidence, I can ask them. But it gives us greater focus.


Interview with Garr Reynolds - Presentation ZenThank you Garr for the wonderful interview.

(that is me with Garr on the right side, excuse the poor quality of the image, but we are using webcam on my Toshiba Satellite A300)

But, the most interesting part of this is, actually meeting him and discussing openly about charting, visualizations. We discussed alot about the kind of mistakes people make when creating charts (he *loved* the article 6 charts you will see in hell and the new chart doctor series we announced). We discussed about his new book – presentation zen design.

There is another exciting thing that I am not announcing now, but you will soon know.

    Interesting that you are posting this at the same time as Doug http://yoursumbuddy.com/regex-function-sum-numbers-string/

    • Luke M says:

      Looks like two different articles about two different subjects, extracting numbers in text vs. summing all the numbers in text. Also, articles are published 20 days apart. Is the interesting part that there were two articles written about Visual Basic techniques within this month?

      • Luke M says:

        Sorry, that should have said 1 day, not 20. Was looking at the wrong thing. I still think it's just a nice coincidences to have multiple articles about VB written. Dick Kusleika also routinely writes about VB at dailydoseofexcel.com

    • Chandoo says:

      What a lucky coincidence. I know about Doug's blog, but havent had a chance to read it in a while. Thanks for sharing the link.

  2. Don Hopkins says:

    I think that the best lesson that can come from the several salary survey solutions is that one should have anticipated the variety of monetary units.  If the survey utilized drop down currency lists and limited the salary field to whole numbers only, etc. the resulting input would have been far cleaner. Sorry, Chandoo, but the messy input was, in my opinion, self-inflicted.

    • Chandoo says:

      You are right. Since there are more than 200 different currencies, I thought a currency field would complicate the survey. The bigger problem was, Google Docs (which I used for survey) does not have an option to capture only numbers. Input fields were by text, so people entered in lots of different formats.

      But I am happy how it turned out. It taught me several lessons on how to clean data.

      Next time I will use a better tool to capture such responses.

  3. Crisu says:

    Your post made me check how the "regular" and "irregular" decimal separators look like in different countries and it appears to be really interesting case. Take a look:
    http://en.wikipedia.org/wiki/Decimal_mark
    Cheers.
     

  4. I am pretty sure you can replace this code block from your article...

    If Text Like "*.*,*" Then
      european = True
    Else
      european = False
    End If

    with this single line of code...
     
    european = Format$(0, ".") = ","
     

    • Just to follow up on my previous post, I think I may have misunderstood the intent of your code. You were not looking to see if the computer system was using a dot for the decimal point, rather, you were looking to see if the Text was using a dot as the decimal point, weren't you? If so, then you could use this single line of code as to replace your If..Then..Else block...

      european = Text Like "*.*,*"

      But what if the number in Text was not large enough to display a thousands separator? Or what if it were a whole number? In either of those cases your original test, and my replacement for it, will fail. Maybe this would be a better test...

      european = Right(Format$(Text, "."), 1) = "," 

      • Chandoo says:

        You are right. I am checking if the text has European format. And I loved your one line shortcut. I did not think of using LIKE in such context. Thanks for sharing that.

         

        Again, you are right that this method would fail if the number is not big enough for a thousands separator. Since my data has annual salaries, all numbers are usually in thousands. So I did not think about it.

        Hi ,

        I have a question please. I'm working on a report that has alphanumeric on it and I only need to retrieve 7 integers that starts with 7 and 3 example SCM RIS PX RIS 02 - 7152349, ADSF\243434134, CM532345 and i need to get the 7152349. Can you please help me on this? I truly appreciate your help!
        Thank you very much!

  5. Tayyab Hussain says:

    Hi-

    The post was wonderful. Please take a look at this function also

    Function ExtractNumber(InputString As String) As String
    'Function evaluates an input string character by character
    ' and returns numeric only characters
    'Declare counter variable
    Dim i As Integer
    'Reset input variable
    ExtractNumber = ""
    'Begin iteration; repeat for the length of the input string
    For i = 1 To Len(InputString)
    'Test current character for number
    If IsNumeric(Mid(InputString, i, 1)) Then
    'If number is found, add it to the output string
    ExtractNumber = ExtractNumber & Mid(InputString, i, 1)
    End If
    Next i
    End Function

    • Bone Bone Gyi says:

      Thank you so much. Your function code is amazing. It very useful for my lesson. Thank you so much.

  6. hpchavaz says:

    To be more international.

    At the beginning, for the rench format :

    If fromThis.Value Like "*.*,*" Or fromThis.Value Like "* *,*" Then

        european = True
    End If

    And at the end :

    ElseIf ltr = "," And european And Len(retVal) > 0 Then
        retVal = retVal & Application.DecimalSeparator
    End If
     

  7. Kris says:

    Hi Chandoo,
    Sorry, but your code does not work correctly with my Hungarian excel. My decimal separator is "," so
    getNumber = CDbl(retVal)
    will not convert the string to value, because you hard-coded "." as separator.
    And, as you mentioned: "method would fail if the number is not big enough for a thousands separator" I would like to add: would fail if the user did not enter the thousand separator and also would fail if the thousand separator is not "," nor "." but " " (space chr) - as in Hungary.
    This two functions could help to determine the system settings:
    application.DecimalSeparator
    application.ThousandsSeparator
     
    Conclusion:
    you say: "We do not need special treatment for regular format (61,000.30) as Excel & VBA are capable of dealing with these numbers by default." - it is true in case you system uses the regular format. 🙂
     
    Cheers,
    Kris

  8. Deependra says:

    Awesome! It works !!
    But how does one take into account negative numbers (say the list has negative numbers and I want to retain those negative numbers)
     
    Thanks.

  9. Akmal says:

    Hi. When I download this example, my excel is not showing formulas exactly. I wanted a ready version of this example, please. Thank you

  10. Kenny says:

    Hi Chandoo,

    Thanks for this brilliant article like many others that you have written for the benefit of many. Unfortunately, I am constantly having problems downloading your sample workbooks. I am currently using Excel 2007, and each time I try to download any of your sample workbooks, for e.g. the 'Extract Numbers Using VBA workbook', I get the following message 'This file is not in a recognizable format'.

    I always get this message each time I try to download any of your sample workbooks. Please kindly advise me on how to resolve this.

    Thank you.

    Kenny

  11. Madhav says:

    I have numbers like 12345-12-1 which I want to extract from text strings. 12345 might be variable there as 123, 1234, 12345, 123456,1234567 or so. When I get that in other cell (Column) I should see multiple entries of similar numbers with - (hyphen). How to do that?

  12. Madhav says:

    Thanks Hui for your response. Thank you for your time to find potential solution for my problem.

    I tried your formula but was not successful in using the same.

    here is more clarification so that you/others could help me.

    Column A has following in Cells A1 to A4.. could be long..
    ABCD 12345-12-1 XYZ 9878-02-9
    LMNOPQ 12345-12-1 STQ 789748-98-5
    NFHFKDJFKDS 123-23-1, NDKANSD
    A FDSAFNDS 12345-12-1, ASNDSAND

    from such data I need to extract the number with hyphens
    remove , immediately after the numbers, separate the numbers with spaces

    Column B shall look like:
    12345-12-1 9878-02-9
    12345-12-1 789748-98-5
    123-23-1
    2345-12-1

    2 separate strings (numbers) having hyphen (-) therein should be separated with space.

      • Madhav says:

        Thanks Hui that worked well with the examples I provided.
        I should have given following type of example:
        2-ABCD 12345-12-1 X-2-YZ 9878-02-9

        in the above case I do not want to extract a number and hyphen which is connected to or is part of text string..

        Can you please help me modify the code to ignore numbers and - with text string.?

        Thanks in advance.

        • Hui... says:

          @Madhav

          So what is the answer expected from
          2-ABCD 12345-12-1 X-2-YZ 9878-02-9

          • Madhav says:

            Thanks for your interest and time Hui.

            so when I have text like
            2-ABCD 12345-12-1 X-2-YZ 9878-02-9 3-abc-4-efg in Cell A2
            in B2 the answer should be only numbers with hyphens and no text with numbers or hyphens
            12345-12-1 9878-02-9 OR
            12345-12-1 some delimiter (, or 😉 9878-02-9

            The logic I thought was (but unable to do)
            1. remove all strings containing text (and - and numbers) and then extract only numbers containing hyphens
            2. Extract numbers in only following format ( # is a digit below) and ignore numbers and hyphens in any other format
            #######-##-#
            ######-##-#
            #####-##-#
            ####-##-#
            ###-##-#
            ##-##-#

            Hope this helps.

  13. Thomas Huettemann says:

    Why not just use the function =getNumber ?

    • Madhav says:

      =getnumber doesn't extract numbers with hyphens..
      also need to ignore numbers and hyphens associated with text string

  14. Deepak says:

    When I use this code that code give me error
    cdb1 is not highlight can u explain me

    • Hui... says:

      @Deepak

      It runs fine for me
      Select the first line and Press F9 to set a stop point
      goto a cell and edit the function and press Enter
      Then you can step through the code when it runs using F8
      report back what happens

  15. Yamin says:

    HI,
    How can we add spaces between numbers and removing decimals.

  16. Yamin says:

    how can we make spaces in the reesult e.g 25 655 2335

  17. Avinash says:

    Dear Team,

    I need to extract number (cheque number) from a cell (some numbers may repeat that to be ignored),

    Text is - :-Inward Clg Cheque 00992924 00992924,BD
    Result should be - 992924

    Kindly help in getting formula for this (please email the code or VBA Code)
