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]

Its possible to display up to 4 text values.
Have a look at the screen shot of an example that I had posted way back at the EHA and figure out how its done !

With Excel 2010 you can use Conditional Formatting to apply custom number formats which can display text. (In older versions you can only modify text color and cell background color, but not number formats.) Using CF allows for an even larger number of different display values.

Hey,
Thanks, this helps. But how do you do it for multiple values where there is a huge amount of non repeating text?
@Soumya
The only way to do more than 4 values is to make the Pivot Table manually with formulas, of course then it isn't a Pivot table
You can of course do it with VBA
You may want to have a look at this description of how to do it here: http://www.clearlyandsimply.com/clearly_and_simply/2011/06/emulate-excel-pivot-tables-with-texts-in-the-value-area-using-vba.html

[...] Pivot Tables take tables of data and allow the user to summarise and consolidate the data at the same time. This is a great and very fast method of analysis but is restricted to handling mathematical functions on the value field resulting in numerical summaries. – read more [...]

There is a very good way actually for handling text inside values area.
First you create a special column on the very left side and call it ID, and put unique ID (numbers only), and then create a pivot table with:
Row Labels and Column labels as you like, and in the Values labels use the unique ID number.
Move the unique ID number (copy paste) somewhere to the right and use vlookup to load the data you need using the ID as reference.
It is a bit longer way but for me it works perfectly to combine values as you like in any moment.
hope helps.

Thank you! I finally understand pivot tables thanks to your clear, concise explanations and examples.
Good Day. This is exactly what i have been looking for. However when i try it on my pivot table or even when i try to recreate this exercise using the sample worksheet, i get this error:
"Microsoft Excel cannot use the number format you typed. Try using one of the built-in number formats."
Same thing here, Excel quite did not like the format in my PowerPivot. Any clues as to what may be going on? Thanks.
I have the same thing happening on my end. I'm running a normal pivot table on a .xlsm file.
@Danzi
What format did you use?
can you post the file ?
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C
MR.A CFVDE2458T
MR.Z AAVCR12548C
MR.X AAAAC1254T
MR.Z AADCD245T
pls. help in table there is name, pan. amount. i have to make pivot table for example
NAME PAN AMOUNT
MR.X AAAAC1254T 500.00
MR.Y AAABR1258C 1000
MR.A CFVDE2458T 2000
MR.Z AAVCR12548C 5451
MR.X AAAAC1254T 45564
MR.Z AADCD245T 4500
how to get pivot tabe so i get PAN no. against Name.
I found an easy way to get text values in pivot table.
I create an other worksheet in wich each cell has a formula that copy the pivot table. The trick is that the formula does a lookup for the numbers in the pivot table.
The formula looks like that:
=IF(ISNUMBER(table!A1);VLOOKUP(table!A1;Code!$A$1:$B$65;2);IF(ISBLANK(table!A1);" ";table!A1))
Code is a worksheet where there is a liste of text /numbers correspondance.
As a bonus The new sheet is easier to format
Additional trick:
In my case, i encoded differents codeid with a power(2, codeId-1) so that summing then is equivalent to concatenate them.
1-A
2-B
4-C
8-D
yields :
5 - AC
14 - BCD
Hi
I want to ask if pivot can display dates in pivot field. As in a column i have customers and in row different items i want to know there last purchase date. anyone help in this??
Hello Guys, Need your help
I am doing some analysis of the cycle time of the product i.e how much time a product takes from manufacturing to the central warehouse.
I have batch numbers for the product and against them i have to pull out the diff. dates
Like the base date is from where the manufacturing start. So i have the batch number,against it's manuf. date. Now i have to pull out the date when it was quality released.
I have the quality released data but the data have duplicates, like i will have two dates or may be three for the same batch. So my main objective is to pull out the date which is latest among them.
BATCH NO. DATE of Mfg. DATE of Quality release
A1 12/4/2014 (HERE I HAVE TO PULL value)
Next Sheet
BATCH NO. DATE of Quality Release
A1 14/5/2014
a2 23/5/2016
A1 12/5/2014
A1 13/6/2014
From this sheet i have to pull up the latest date format of date here is dd/mm/yyy
TIA

This is great thank you.
