First some good news,

On 21st November, 2010, our little blog received its 10,000th comment!

Thank you so much for making this happen.

Those of you reading chandoo.org for a while know my penchant for comments. I have learned a lot of excel tips & ideas just by reading the comments you posted on this blog. I think comments are one of the best parts of this blog. So, naturally, I wanted to celebrate this milestone, with something big & awesome.

My intention was to download all the 10,000+ comments and play with the data to come up with something outstanding, like a dashboard. It took me 2 days to conceptualize and create this beauty.

10,007 comments visualized in an Excel Dashboard:

Summary of Findings from the Dashboard:

  1. Out of 10,007 comments, 8766 are comments left by people and 1241 are ping-backs (a comment made automatically by other blogs when they link to chandoo.org).
  2. Roughly 20% of comments are @ replies.
  3. 31 posts had more than 50 comments each. The maximum comments were 313 on the last visible cell poll.
  4. These 10,007 comments came from 2507 unique people. Top 20 commenters made 28% of comments.
  5. Median words per comment are 33. You said a total of 485,000 words so far. Impressive.
  6. There were only 5 days with zero comments in 2010 (as against 66 in 2008 and 15 in 2009).
  7. Fridays are most popular days for commenting with 20% comments coming in.

Learn How Dashboard is Constructed in a Crash Course:

I made this dashboard with lots of love & coffee. Of course, coffee wont magically turn data into in-cell charts. We need to arm twist our data and get the insights out ourselves.

That is why I made an hour long tutorial explaining how I constructed this dashboard. In the video I explain how I came up with the design, what formulas I used to cleanse & process the data, how various charts were constructed, what techniques I have used to put this together.

As this video is kind of advanced training on dashboards, I have decided to sell it. You can get a copy of the video & unlocked excel files for $37.

What you get with the purchase:

  • A HD video explaining the dashboard construction process
  • Same video in iPod compatible format for watching on the go.
  • 2 Excel files, the original version & instructor version (unlocked)

Please note: You will not enjoy the video if you are an Excel beginner. Instead go thru Excel Dashboards page to equip yourself with necessary dashboard & charting skills before getting a training like this.

How is this Dashboard Made?

If you are curious to know which nuts & bolts are used in the dashboard, read up:

  • The chart showing monthly trend of comments and day of week distribution are 2 different charts, one arranged on top of other.
  • The word cloud showing relative frequencies of words used in comments is made using wordle. This is the only non-native Excel part of the dashboard.
  • The Top 10 tables at the bottom are incell charts with some fancy colors.
  • I have used pivot tables, SUMPRODUCT, SUMIFS, INDEX+MATCH, VLOOKUP formulas to process the data.
  • Word counts are generated by processing the comment text using this technique.

Download the Dashboard File:

Click here to download a locked copy of the dashboard [mirror here]. You can examine the dashboard, but you can not alter it as it is password protected.

If you want an unlocked copy, you can get it by purchasing the video tutorial. Click here (or here).

    Nice Trick.. Clever use of cell references

    Here is a formula I tried to create:
    =SUMPRODUCT(((NOT(ISERROR(SEARCH(L5,B4:H14))))*1),(B5:H15))

    It takes care of Caveat #1 (can handle text), but Caveat #2 remains.

  2. PeterB says:

    In situations like this, I will often use VBA to restructure the data (2 columns: dates and values) on to a new worksheet. I can then use this 'clean' source for data analysis (formula or pivot table).

    =SUMPRODUCT(((NOT(ISERROR(SEARCH(L5,B4:H14))))*1),(B5:H15)) and complex formulae in general are all very well but when you come back to them in a few weeks / months time, it is not at all easy to see what they do and what the limitations are.

  3. Somendra Misra says:

    Hi Chandoo,

    I had used this type of cell ref. various times while calculating average.
    But for the situation here try below formula . Note this is an array formula and must be confirmed with Ctrl+Shift+Enter.

    =SMALL(IF(MMULT((L5=B4:H14)*IF(ISNUMBER(B5:H15),B5:H15),{1;1;1;1;1;1;1}),MMULT((L5=B4:H14)*IF(ISNUMBER(B5:H15),B5:H15),{1;1;1;1;1;1;1})),1)

    Regards,

  4. Somendra Misra says:

    Hi, I think Using SEARCH in here will create a problem say there is a text like SUN and another text SUNLIGHT both result will be added by SUMPRODUCT.

    Regards,

  5. Elias says:

    Array option.

    =SUM(IF(MOD(ROW(B4:B14),2)=MOD(ROW(B4),2),IF(B4:H14=L5,B5:H15)))

      @Elias,
      Nice approach.
      Although not requested - the formula I suggested closes all possibilities.
      Criteria: _____ Value to retrieve:
      Date__________ Numeric
      Date__________Textual
      Textual________Numeric
      Textual________Textual
      While your formula copes with only the 3 first combinations.

      • Elias says:

        @Michael,

        Sorry but I don’t understand your point. I believe the challenge was to return the summary of a given date. What is your really volatile formula doing that mine is not?

        Regards

        • Michael (Micky) Avidan says:

          @Elias,
          I didn't say that the challenge differs from what you just mentioned/aimed to nor that your formula doesn't provide the requested result.
          Please read my previous comment again and focus on the last combination (TEXT / TEXT).
          I, myself, always try to provide a global Formula that is capable to handle all sorts of data.

          • Elias says:

            @Michael,
            I see your point, but you are missing the below points if you are trying to cover all sorts of data.

            What happened if the lookup value does not exist?

            Do you want the first, second, summary, concatenation of the values if the look value is repeated?

            See they are too many possibilities to be cover with just one formula.

            Regards

  6. Michael (Micky) Avidan says:

    1) The range: B4:H15 was named: RNG.
    2) The following Array Formula was "retrieved from my sleeve" and I hope it can be shorten.
    3) The formula seems to take care of BOTH(!) caveats.
    -------------------------------------------------------------------------------
    =OFFSET(INDIRECT(ADDRESS(SMALL(IF(RNG=L5,ROW(RNG),""),1),MOD(SMALL(IF(RNG=L5,(ROW(RNG))+COLUMN(RNG)/10),1),1)*10)),1,)

        @Elias,
        Let's hope the following Array Formula "closes all open doors".
        Again - it has nothing to do with your formula which works fine as long as the 3 first mentioned combinations are concerned.
        -------------------------------------------------------------------------------
        =INDEX(RNG,LARGE(IF(RNG=L5,MOD(ROW(RNG)-1,2)*(ROW(RNG)),""),1)-2,(MOD(SMALL(IF(RNG=L5,(ROW(RNG))+COLUMN(RNG)/10),1),1)*10)-1)

        • Elias says:

          Ok, if you insist. The following will cover all the scenarios you listed. However, I’ll never recommend/use such of formula.

          Defined names:
          rDat = $B$4:$H$15
          rRow =ROW(rDat)-MIN(ROW(rDat))+1
          rCol =COLUMN(rDat)-MIN(COLUMN(rDat))+1
          rInc =MOD(rRow,2)=MOD(MIN(rRow),2)

          L6=INDEX(rDat,MAX(IF(rInc,IF(rDat=L5,rRow)))+1,MAX(IF(rInc,IF(rDat=L5,rCol))))
          Array Enter

          Regards

        • Frank says:

          @Michael,

          unfortunately, your array formula still seems to return wrong results (eg 3-Nov).

  7. Magda says:

    If data are organized like in the example, ie. looks like a calendar, the INDEX formula seems quite simple:
    =INDEX($B$4:$H$15,ROUNDDOWN((L5-B4)/7,0)*2+2,MOD((L5-B4),7)+1)

    • Marc says:

      Yours is effectively the same as what I just came up with, and I believe this is the optimal answer to this particular problem.

      My solution, before I saw yours:
      =OFFSET(B5,QUOTIENT(L5-B4,7)*2,MOD(L5-B4,7))

      OFFSET will work for an arbitrary list size, but INDEX might be easier to read.
      QUOTIENT does the round and division in a single step.

  8. XOR LX says:

    If there's an improvement over Elias's solution then I for one can't see it.

    Perhaps a non-CSE version which would also mean that only two references (B4:H14 and B5:H15), as opposed to three (B4, B4:B14 and and B5:H15), would require manually amending should the data range change, i.e.:

    =SUMPRODUCT((ISEVEN(ROW(B4:H14)-MIN(ROW(B4:H14)))*(B4:H14=L5)*B5:H15))

    I suppose we could make it a single, uniform range reference:

    =SUMPRODUCT((ISEVEN(ROW(B4:H14)-MIN(ROW(B4:H14)))*(B4:H14=L5)*OFFSET(B4:H14,1,,,)))

    which might be more appropriate should we e.g. wish to use a Defined Name for our range, i.e.:

    =SUMPRODUCT((ISEVEN(ROW(Rng)-MIN(ROW(Rng)))*(Rng=L5)*OFFSET(Rng,1,,,)))

    though whether that compensates for the extra, volatile function call is something to be debated.

    Regards

  9. Mahir says:

    I have tried something and then my Excel workbooks got shut down. Maybe that was too much?

    Anyway here is what I've tried:

    =SUMPRODUCT(INDEX(B5:H15;IF(ISEVEN(ROW(B5:H15));ROW(B5:B15)-ROW(B5)+1);{1\2\3\4\5\6\7}))

    Guess that was wrong? Would this approach work anyway?

    Looking forward to learn something from you Excel Experts.

  10. XOR LX says:

    @Michael Avidan

    As it stands that is not a very rigorous construction.

    You say "I, myself, always try to provide a global Formula that is capable to handle all sorts of data", which is a wonderful philosophy, but isn't it at least as important that we ensure that our formulas are independent of the row and column references of the data range in question, so that, should that range change, we do not have to re-work our solution?

    What happens with your formula, for example, if RNG is instead re-located one row down, from B4:H15 to B5:H16?

    When a formula is reliant upon the addition/subtraction of certain constants within the formula, which themselves are necessarily dependent upon the specific rows/columns in which the data lies at any given time (e.g. the -1 in MOD(ROW(RNG)-1,2)), then that formula is not a very flexible one.

    Hence the reason for my choice of a slightly longer construction:

    ROW(B4:H14)-MIN(ROW(B4:H14))

    which ensures that this part of the calculation is not dependent upon the precise location of the data range within the worksheet, and so will give correct answers even if that range is re-located.

    Regards

  11. Haz says:

    {=OFFSET(B4,MAX((B4:H15=L5)*ISODD(ROW(1:12))*ROW(1:12)),MAX((B4:H15=L5)*ISODD(ROW(1:12))*COLUMN(A:G))-1)}

    • Haz says:

      Non-array formula:
      =INDEX(B4:H15,SUMPRODUCT((B4:H15=L5)*(ROW(B4:H15)-ROW(B4)+1)*ISODD(ROW(B4:H15)-ROW(B4)+1))+1,SUMPRODUCT((B4:H15=L5)*(COLUMN(B4:H15)-COLUMN(B4)+1)*ISODD(ROW(B4:H15)-ROW(B4)+1)))

      Using one range (B4:H15), one reference (B4), one lookup value (L5) and no INDIRECT or OFFSET.

  12. MF says:

    My trial with defined names:

    DateRange
    =$B$4:$H$4,$B$6:$H$6,$B$8:$H$8,$B$10:$H$10,$B$12:$H$12,$B$14:$H$14

    Position
    =RANK('lookup problem'!$L$5,DateRange,1)

    L6
    =OFFSET(B4,ROUNDUP(Position/7,0)*2- 1,IF(MOD(Position,7)=0,6,MOD(Position,7)-1))

  13. Jeff Weir says:

    I'd probably just run with something like:
    =SUMPRODUCT((B4:H14=L5)*(MOD(ROW(B4:H14),2)=MOD(ROW(B4),2))*B5:H15)
    ...which is basically the same as Elias' but without the IFs

  14. Bermir says:

    The opposite of elegant but it works...

    =INDEX(B4:H15,IFERROR(MATCH(L5,B4:B14,0),0)+IFERROR(MATCH(L5,C4:C14,0),0)+IFERROR(MATCH(L5,D4:D14,0),0)+IFERROR(MATCH(L5,E4:E14,0),0)+IFERROR(MATCH(L5,F4:F14,0),0)+IFERROR(MATCH(L5,G4:G14,0),0)+IFERROR(MATCH(L5,H4:H14,0),0)+1,IFERROR(MATCH(L5,B4:H4,0),0)+IFERROR(MATCH(L5,B6:H6,0),0)+IFERROR(MATCH(L5,B8:H8,0),0)+IFERROR(MATCH(L5,B10:H10,0),0)+IFERROR(MATCH(L5,B12:H12,0),0)+IFERROR(MATCH(L5,B14:H14,0),0))

    rownum = SUMPRODUCT(('lookup problem'!$B$4:$H$14='lookup problem'!$L$5)*ROW('lookup problem'!$B$4:$H$14)*ISEVEN(ROW('lookup problem'!$B$4:$H$14)))

  16. Venky says:

    How about SUM(IF(B4:H14=L5,B5:H15)) with array..it should work

  17. xen says:

    Sorry, Chandoo, you can't find stuff this way in every possible scenario.
    What if 2014-10-01 sales would equal 41.927 ? Which is serial number for 2014-10-15 ? SUMIF would fail to retrive correct answer. And your example data suggest that such number is possible in your table.

    It's better not to search through dates and numbers at the same time.

    If I'd solve a problem like this, it'd reformat table first so I get one column with dates and the other with numbers.

    In this case, formula to form date column would be:
    =INDIRECT(ADDRESS((INT((ROW()-4)/COUNT($B$4:$H$4))+1)*2+2;MOD(ROW()-4;COUNT($B$4:$H$4))+2;4;1))
    and numbers would be the same formula with sight adjustment (+3 instead of +2 at the end of first argument):
    =INDIRECT(ADDRESS((INT((ROW()-4)/COUNT($B$4:$H$4))+1)*2+3;MOD(ROW()-4;COUNT($B$4:$H$4))+2;4;1))

    And now you got two columns that you can safely use for searching!

  18. xen says:

    Oops, sorry, you actually mentioned that it doesn't work if number=date! I missed that part 🙁

  19. Vad says:

    ={OFFSET(A1,SUM((B4:H14=L5)*ROW((B4:H14))),SUM((B4:H14=L5)*COLUMN((B4:H14)))-1)}

    Works for all data... the solution I got for indirect looks little lengthy

    I want to count last 20 records of a person, whose marks is greater than 2 and grade "manager". ....

  22. Marc says:

    Simplest I can come up with. No limitations for either 1 or 2. This does assume dates are an ordered list with 7 per row, and 2 rows per set. Assuming this is always true this will work for an arbitrary long list of dates.

    =OFFSET(B5,QUOTIENT($L$5-$B$4,7)*2,MOD($L$5-$B$4,7))

    • Michael (Micky) Avidan says:

      @Marc,
      Nice approach - however, as there are no "Negative Dates" - try:
      =OFFSET(B5,INT(L5-B4)/7)*2,MOD(L5-B4,7))

  23. Vijaykumar Shetye says:

    =OFFSET(B4,ROUNDUP((L5-41911+1)/7,0)*2-1,MOD(L5-41911,7))

    B4 has been used as reference cell for OFFSET().

    FOR ROWS:
    ROUNDUP(....,0) gives the integer value of a division. In case of presence of a remainder, ROUNDUP will add 1 to the Quotient.
    As opposed to ROUNDUP(), the INT() or QUOTIENT() functions eliminate the remainder.

    41911 = 01-Sept-2014, the first date in the data.

    *2 has been used because there are 2 columns per set of data.

    /7 has been used because there are 7 columns per set of data.

    For columns
    MOD(L5-41911,7))
