If this Excel problem is a Bollywood (Indian movie) plot, it would go like this:
Situation: Your boss gave you a worksheet. It has a lot of number chunks. And you need to calculate the sum of each chunk. Quickly!
Twist #1: The villain (your boss, who else) has abducted your spouse. For every extra hour you spend on the problem, your boss will make your spouse go thru one of the boring 97 slide strategy presentations. And his laptop is full of those strategy presentations.
Twist #2: The F1 key on your keyboard is missing.
Twist #3: The coffee machine in your floor is broken again.
Twist #4: And just when you are pressing CTRL+S, the movie steers in to an item song.

Fortunately, no one abducted your spouse. And hopefully the coffee machine is working. But the Excel problem remains unsolved.

Sporadic totals
This problem is based on a call I received last week from one of our readers in UK. He had a worksheet full of numbers with blank rows between every few numbers. And he wants to calculate the totals of individual chunks of numbers quickly. He cannot write one formula and paste it everywhere as the chunks are not uniformly sized. He cannot write individual formulas as the data is very large.
So what to do?
If we are still in a Bollywood film, you can write all the 10,000 formulas and simultaneously sipping screwdrivers & shimmying to a snazzy song with sexy starlets.
Alas, this is not a movie.
But we still manage to look awesome. Thanks to superb sidekicks – Goto Special & Autosum.
Calculating Sporadic Totals in a second
See this short video to understand how to calculate sporadic totals in a few seconds. With the time saved, you could fix yourself a cocktail (or coffee) and hum a beautiful song.
Watch the video on our YouTube Channel or Facebook Page.
Sporadic Totals – Alternative treatment
It is an awesome co-incidence that both MrExcel (Bill Jelen) and Kevin Lehrbass also published videos about this concept around the same time. MrExcel shows how to use VBA to do this, where as Kevin talks about using formulas. Check out both videos too.

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...

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?
