Today we will learn Excel SUBTOTAL formula and 5 beautiful reasons why you should give it a try.
SUBTOTAL formula is used to find out subtotal of a given range of cells. You give SUBTOTAL two things – (1) a range of data (2) type of subtotal. In return, SUBTOTAL will give you the subtotal for that data.
Unlike SUM, AVERAGE, COUNT etc. which do one thing and only one thing, SUBTOTAL is versatile. You can use it to sum up, average, count a bunch of cells.
Here is the SUBTOTAL syntax:
=SUBTOTAL (TYPE OF TOTAL, RANGE OF CELLS)

So, for example, =SUBTOTAL(9,A1:A10) will give us the sum of all values in A1:A10, provided none are filtered(more on this filtering thing below). That is because “9” stands for SUM in SUBTOTAL lingo. If you want a count of values, you can use “2”.
Hmm, that sounds like any other formula, what is so special about it?
Well, SUBTOTAL is not just any other formula, it is a special one. We don’t need to be Jedi masters to tell that force is with SUBTOTAL.
Here I have listed 5 reasons why this is such a special formula.
1) You can use SUBTOTAL to find sum of filtered values
I think the title says it all. See this example to know more.

2) You can use SUBTOTAL to ignore values in hidden rows
Often, we use hide rows feature in excel to remove irrelevant items from view. You can use SUBTOTAL with special type codes so that values in hidden rows are neglected.
For eg. SUBTOTAL(9,A1:A10) finds the sum of values in cells A1:A10 where as SUBTOTAL(109,A1:A10) will find sum of values in visible rows only.
3) You can use SUBTOTAL to dynamically summarize data
Since the “type of total” is a parameter to SUBTOTAL, we can use that to make a dynamic summary like this:

This is very handy in dashboards or when you don’t have space for everything.
4) If there are subtotals in SUBTOTAL range, they will be neglected

This is a killer feature of SUBTOTAL. If you have any SUBTOTAL formulas in the input range of another SUBTOTAL formula, these values are neglected so that double counting is avoided. Need I say more?
5) You can automatically create SUBTOTALs using Excel Data Tools
While SUBTOTAL formula looks kind of neat, writing them when you have tabular data can be a drag. But you don’t have to worry about that. In Excel’s Data menu / ribbon, there is an option on called “Subtotals” that automates the whole process for you.

To generate automatic SUBTOTALS, just select your table of data, go to Data ribbon (or menu) and click on “Subtotals”. This will launch a Subtotal dialog where you can easily specify the type of total grouping you want.
That simple!

Have you used SUBTOTAL formula?
I have never really bothered to test SUBTOTAL formula until few days ago. Now that I found some really cool uses for it, I am itching to implement some of them in future. What about you? Have you used SUBTOTAL formula before? Do you got any tips to share? Please use comments to discuss.

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?
