We, data junkies, love pivot tables. We think pivot tables are solution for everything (except for may be global warming and that broken espresso machine down stairs).
Today, we are going to learn 5 awesome pivot table tricks that will make you a star.

Drill down pivot tables | Change Summary from Total | Slice & Dice Pivots | Difference from last month | Calculated Fields in Pivots
(If you are not familiar with basic pivot tables, you should check out this excellent pivot tables tutorial)
1. Drill down on your Pivots with Double click
This is by far the simplest and most powerful pivot table trick I have learned. Whenever you want to see the values behind a pivot field just double click on it.
Lets say, the sales of Lawrence in Middle region is $5,908 and you want to know which items contribute for this total, when you double click on the number $5,908 excel will show a list of all the records that add up to this number, neatly arranged in a new worksheet. Instant drill down.
See this magical trick in action.
2. Summarize Pivot Data by “Average” or some other formula
By default excel summarizes pivot data by “sum” or “count” depending on data type. But often you may want to change this to say “average”, to answer questions like “what is the average sales per product”. To do this, just right click on pivot table values (not on row or column headings) and select “summarize data by” and select “Average” option.
(In excel 2003, you have to do this from “field settings” menu option)
3. Slice & Dice your Pivot Tables with Grace
Re-arranging pivot table layouts is as easy as shuffling a pack of cards. Just drag and drop the fields from row areas to column areas (vice-a-versa) and you have the pivot table rearranged.
Here is a simple screencast explaining the secret
4. Show difference from last month (or year) without bending backwards
We all know that you can show monthly summaries using Pivots. But what if your boss wants you to also include “difference from previous month” as well? Now, dont rush back to source data and add new columns. Here is the right trick to make you a star.
- Just use field settings to tell excel how you want the data to be summarized.
- Right click on any pivot table value, select “value field settings”
- Now go to “Show value as tab” and Change “Normal” to “Difference from”
- Select “Previous” from Base-item area. Leave Base field as-is.
Now, your pivot is updated to show difference from previous column.
Bonus: There are quite a few value field settings you can mess with. Go play and discover something fun. 🙂
5. Add new dimensions to your Pivot Reports with Calculated Fields
Let us say you have both “sale” and “profit” values in your source data. Now, your boss wants to know “profit %” in the pivot report (defined as Profit/Sales). You need not add any extra columns in your source data, instead you can define custom calculated fields with ease and use them in pivot reports.
- To do this, Go to pivot table options ribbon, select “formulas” > “calculated field”
- Now define a new calculated field by giving it a name and some meaningful formula.
- Make sure you adjust the cell formatting so that output of calculation can be displayed (for eg. change number to % format)
(In excel 2003, the formula option is available from Pivot menu in toolbar)

I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

Chandoo,
millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.
one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...
i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

Martin

Chandoo -
You ask "Can I use an alternative to pie chart?"
I answer in You Say “Pie”, I Say “Bar”.
This visualization was created because it was easy to print before computers. In this day and age, it should not exist.
I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
My money's with Jon on this topic.
The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...
@Jerome.. Good point. Also sometimes, there is just no relationship at all.
@Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂
@Jon .. very well done sir, very well done.
good points every one...
I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

Good article. Is it possible to do that with line charts?
Hi,
Is this available in excel 2013?
