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:
(compare this with actual chart on Google)
How I made the flu-trends chart in excel?
- 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.
- 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.
- 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.
- 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.
- 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().
- 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]
- 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.)
- I choose to drop the colorful legend as it adds little value.
- 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]

Looks good, Mara. Keep up the good work!
Thx Mara, your work is great, congratulations...
wow ! Great stuff Mara !!
I am amazed on the work you did !
What I like about your dashboard
1. The first impression is the colors used. Very smart use of colors that matches each other, easy on the eye - make people wants to find out more !
2. Clear message shown for the tweetboard for Quick overview on the state of situation.
3. Use of creative titles for your charts "Information Desk".
4. Clear and uncluttered charts. Gives reader a clear perspective with good use of charts colors too.
5. Good use of Legend to describe what color meant "Highest Sales out of the three months"
6. Of course, good use of Check boxes and Slider bar to offer interactiveness on your charts.
Suggestions
1. You may want to consider formatting your Y and X axis labels to show thousands, in $500K format instead of $500,000, so you can even made your chart look much neater.
2. Budget Variant Chart - This one is special...I took a second look and try to understand it. I am not sure if this is the best chart to visualize Sales VS Budget and Variances. And the Variance of 16.19% is positive, so u may want to use conditional formatting to make it green color, red if negative.
Overall is Great Work and Great Effort !!! Keep it up and I am so proud of you !

Great Work Maya, just wondering if "5" Scrollable list of various gift shop items, can compare the previous 2 and current month selected in the above picklist, just one more suggestion if we can use top 5 gift category by using donut and bar mix chart to show sales mix for different months
Chandoo I would like to thank you for posting such helpful tricks for creating dashboards, I have learned a lot from your KPI Dashboard demo, I have created one dashboard to compare performce of Sales Associates, thaks a lot again
Thanks for the idea! Great job! You are giving me a lot of inspiratons!
Thanks everyone for the nice comments. I'm such a novice at this so I was so grateful for Chandoo's class and for everyone who submits ideas on his blog.
Francis: Thanks so much for your comments. You're an inspiration. For the budget variance chart, I actually got that idea from one of Chandoo's post on budget vs actual. There was one that was simple and easy to read so I learned how to do that and made it dynamic. I'm open to any other ideas you have for budget vs actual. I'm always looking for ways to improve.
Sabrina: Thank you for you for your suggestion on the top 5.

Excellent dashboard Mara.
The best I like about the dashboard is the choice of colors. They are cool and not distracting. Thanks for sharing the file.
@Chandoo

Great work Mara ! Thanks for sharing .
Mara, I liked the line, "Need to be more helpful." Our government needs to print this line, laminate it and post it in all government offices for the staff to see.
Hi there, i have been recently visiting this blog it is really great, the best one for Excel, wish Chandoo great success ahead.
I have one query, if you protect the data sheet the chart with the checkbox gives and error saying the data is protected and cannot be modified, is there a way around. This is cause if we want to publish this to someone who should only see it and do no changes to the data, is it possible please guide.
This could be a silly but bear me i am novice to excel 🙂
Thanks.
nice work.
inspired me a lot, working on few dashboard projects...

Dear Chandoo,
The word Dashboard in the heading is misspelt.
Wow. Very Nice work Mara. Next week I am going to take the Course, I will try to post my work here.
Thank you so much for your helpful blog. Always appreciated your tips and tricks.
I am proud that you belongs to our Vizag City.
The above comment, I forgot mentioned about Chandoo, those two paras is about Chandoo. 😀
Thank you Mara!
Thx Mara, your work is great, congratulations…
Great Work Mara!!!!!!!!!!!!!!!!!!!!!!!!!!
Hi Chandoo,
I had been following your blogs for tips and tricks on excel. I am working with Media agency and we collect the data. Now this data has several parameters based on several legends. For eg Class A - legend color red, classB - legend color green and so on. Class A has several characteristics and parameters and heading etc. Now everytime we gather data and make pivot then based on the data in the pilot tables - top 10 we need to insert those in charts manually and also need to change the colors of legends and also. We create nearly 300 slides every month sector wise and it takes nearly our 4-5 days in doing that. Do you have any sample dashboard which will be helpfull to us and we can create it in a day.
Thanks really amazing one,
it helped me in desgining OTACE report
