Flu Trends Chart in Excel [Yes, we can edition]

Last week I have reviewed Google’s flu trends chart and told you why it is an awesome chart. This week, I am going to show you how such a chart can be constructed in Excel.

First let me show you what I am able to do in Excel:

Flu Trends Chart in Excel

(compare this with actual chart on Google)

How I made the flu-trends chart in excel?

  1. Data, Data, Data: Data plays an important role in complex charts like these. The source data is thankfully available for download from Google.  Flu incidence data is available by week (Sunday to Saturday) for every week since 28th Sep, 2003. For each week the data if given for all regions in various columns. But I was not able to use the data “as-is” to construct this chart. I had to massage and rearrange it a bit.
  2. The main issues is how flu season is classified (it starts on July and ends in June) and how the data is (we got weekly flu incident data, starting from Sunday to Saturday). The main issue here is each year, the weeks start on different dates. For eg. first Sunday in 2010 was on 3rd Jan where as in 2009 it was on 4th Jan. I tried using WEEKNUM() formula (examples), but it didn’t work well with the flu season (Jul to Jun). So I did some basic date math and ended up mapping weeks uniformly across years.
  3. The next issue is taking one big table of data with dates in rows and regions in columns and transform it to weeks in rows, years and columns and actual flu data for the selected region in the cells.
  4. Then I set up 2 cells, one where user would specify “region” and other where a comparison “year” can be selected. I have used data validation to control the valid inputs.
  5. I used the MATCH, INDEX formulas to fetch corresponding weekly values for all years for selected region. Thanks to MATCH, INDEX and HLOOKUP formulas, this is not such a big task either. And if the optional comparison year is specified, we repeat that years values in another column. Otherwise that column is NA().
  6. Using these columns, I made a line chart. Then I cleaned up the chart and formatted the 2009-2010 series in thick blue and rest all in thin light blues. The optional comparison series was colored in red (for contrast). [related: line chart examples]
  7. The only remaining piece is to show the heat map of flu intensities below the chart. For this I have used the very useful 3 color scale conditional formatting setting in Excel 2007. (of course, I had to setup some extra calculations so that the intensities are normalized across the region / years and change when user selects a new region, but you already guessed it.)
    Excel Conditional Formatting - Heatmaps
  8. I choose to drop the colorful legend as it adds little value.
  9. The rest is some formatting and presentation.

What I learned from this experience?

  • When I looked at Google’s chart, I doubted if it can be created in Excel. But I was wrong. It can be done in excel, and it takes no more than 2 hours.
  • Data and structure of it play extremely important role in any visualization.We should understand the data and know how to arrange / transform / massage it, to make better charts.
  • Date formulas are a flu in the nose.
  • Excel 2007 conditional formatting is just awesome. [more examples]
  • INDEX, MATCH, LOOKUP formulas are very powerful. I *respect* them. [here is a tutorial]

      Hi there:

      I'm interested in understanding exactly how contestants #'s 1, 8 got their surplus or shortfall to show up at the top of the bar (is this overlapped or stacked somehow) and change colour?  I hope this makes sense.  I've tried to find samples and I can see contestant 8 (cuboo) may have used something called graphomate but I can't use this.  

      I need to create a bar chart that shows budget, and actual variance whether it be a surplus or a shortfall and I would like make it look like option 1 or 8 above but haven't  a clear idea how to do it...any help would be greatly appreciated!

      Regards..Linwe

    #6 is the best here. Simple, no extraneous visual effects.

  3. Kevin Stanford says:

    I was all set to vote for #9...until I noticed its lack of y-axis labels. So I have to go with #6 also.

  4. I think #6,#9 is enough .

  5. Barfly says:

    #9 is my favorite
    Nice data/ink ratio 😉

  6. Tony Rose says:

    I agree with Jon - #6 for me.

  7. Gale says:

    8 & 14

  8. Fabrice says:

    I go for # 9 (simple) and #14 (complete)

  9. fulvioo says:

    I go for cuboo #8
    cheers

  10. Robert says:

    #6 for overview at a glance / top management
    #8 for deeper analysis / those who need more detailed information

  11. Bob Gannon says:

    #14 although I think you only need the bottom panel and I then would stack the Center charts vertically to make Center comparisons easier.

  12. Denise says:

    #10 gets my vote.
    If there is a second place, then #14

    Hi, if I was not wrong, Samples 3,4 and 5 were created using Tableau software and not Excel. For more information on Tableau you might want to visit http://www.tableausoftware.com/. It was initially designed by Prof. Pat Hanrahan and his PhD students. I am not their salesperson but I thought someone might want to know more about this particular technology.

    • Linwe says:

      Hi Tin Seong Kam:
       
      Thanks - I have looked at Tableau before.  I have also found the means to reproduce something similar to chart 8 without using graphomate, and also chart 7.  I proposed chart 9  as well but the overlap is confusing to some.
      I am really not too concerned about showing actual budget figures but the variance in $ and % is important for my particular use.  That is why I gravitate to the charts that seem to easily tell us that we have a surplus or a shortfall.  
       
      Thanks!

    Number 8 by far. Even though it's not part of the data display, the comments feature sells me. Variance explanations are as important as the actual variances.

  21. Cyril Z. says:

    I visually prefer #8, but #3 is really easier to understand, even if it lacks a lot of information (inverting budget/actual), legend, etc...

  24. anyone willing to post their xls for these? Some really excellent exmaples.

  25. PublicSectorPlanner says:

    To avoid the summary execution of the person presenting these to an executive team these charts must handle overspending as well as underspending, be comprehensible in 5 seconds and show the key fact clearly. The key fact isn't budget or actual - it's the magnitude of the gap!

    Therefore:

    #14 for nailing the key fact and being able to handle overspending. The winner therefore.
    #6 for nailing speed-reading and being able to handle overspending, but somewhat obscuring the key fact. Second place.
    #8 for nailing information depth and aesthetics. Third place.

    I really wanted #8 to win, but that's the technician's view not the end-user's.

  30. Shazbot says:

    Does anyone know what type of chart #6 is (chart name?)? Also, how do I create this is Excel 2007?

  31. Hui... says:

    @Shazbot
    I'd call it a Column and Bar chart, but don't get hungup on names

    To make it try this:

    Setup the chart as a Clustered Column Chart
    Change the Series so there is 100% overlap, ie: One column is in front of the other
    Change the Budget series to a line chart
    Set the line color to none
    Set the marker style to a Flat Line
    Change the marker width to make it the same width as the bar
    Change colors and other chart properties to suit

    Dear Chandoo,

    How do I create Chart #10 (comparing Budget vs Actual Performaces) by cost center by quarter without the cumulative performance. Do you have an actual example that I could use?

    Thanks,

  38. OKI says:

    HI

    Does anyone can help me to a to create chart #7? I'm beginer in excel , I started to work two weeks ago and my boss ask me to follow the budget/actual until the end of the year.

    @OKI, Greg

    I have made a mockup of #7 and #10
    It is available at:
    http://chandoo.org/wp/wp-content/uploads/2009/04/Bud-Act-visualizaion-challenge-7+10..xlsx

    #10 is a straight, Pivot Chart/Table but the data has been rearranged to get it into the pivot table

    #7 is 2 charts, being a simple Bar Chart and a Scatter Chart with 100% Error Bars
    I have used Named Formulas for the two charts.

    I think 1 & 3 are good.

  43. Sawan says:

    Hi Chandoo,
    Please can you provide a link of the excel sheet for 1. Chart "3 colors and everything is clear"

    I would like to drill into the spreadsheet and learn the secrets as how the chart was made.

    Many thanks,
    Sawan

  44. Hui... says:

    @Sawan
    It is probably 12 seperate charts, I will assume snapped to the underlying cells to ensure they are the same size
    The left 3 Charts have a vertical Axis
    The bottom 4 Charts have a horizontal Axis
    The remainder have no axis
    The remaining text maynot be part of the charts but is probably cell content

    • Chandoo says:

      @Satyapal... you can only use static images or slide animations in Power Point. Not features like pivot tables or drop downs. However, you can embed the entire workbook (or sheet) in a presentation. When clicked this will just open Excel so your users can play with the data.
