Pivot Table 2007 – First Pivot
Table
The process to set
up a Pivot Table is fairly simple – Just highlight the data base
that you want to turn into a Pivot Table, making sure that you have
met all the requirements of a Pivot Table- no sub-totals, no
columns without headings, no duplicate headings, no merged cells,
correctly formatted dates etc.
You go to insert and
you see there is something called Pivot Table – I am going to
choose Pivot Table for now. The Pivot Chart will be explained later.
Click on Pivot Table you will see Excel produces this table –
first thing it says it thinks it is going to use the cells in the
data base and it is always useful just to check that it has guessed
correctly. It looks like it is looking in the right area. You can
use external data which will be covered later. You also get asked
where do you want the Pivot Table to appear – either in a new
worksheet or else in an existing worksheet. If you do ask for
existing worksheet it will ask you where to place it. We are going
to say new worksheet. When I click OK you’ll see it sets up the
Pivot Table for your first time use.
Just to explain some
of the aspects about a Pivot Table. The first thing to notice is
when the Pivot Table is active you will find you have got a Pivot
Table Field List and that In your ribbon you have a new item called
Pivot Table Tools consisting of Options and Design. If you click in
a cell outside the pivot table, these disappear and in order to get
them back just click into the Pivot Table area. You’ll notice with
the ribbon there are a whole bunch of options which we will cover at
various stages. You can see there are a number of options here –
if you click on the Design Tab you will see again a whole variety of
options particularly around the Style of your Pivot Table. We will
look at those later.
On the right hand
side you’ll notice the Pivot Table Field List – if you look here
you’ll see that these labels correspond to the column labels in
your underlying data base, so here you will see date, time,
duration. This is one of the reasons why the labels need to be
descriptive because this is all you have to work with.
At the bottom here you will see some empty blocks and
you’ll see that this section is for the
Report Filter, this is for where the Column labels will go, this is
for where the Row labels will go and this is where the Values can
go. You will also notice there is something here called Defer Layout
Update. If you click this on and off what happens is as you build
your Pivot Table you can decide whether the
screen will update immediately or it will wait until you have
finished all your
changes before you then push update.
Let’s show how
easy it is to set up a Pivot Table by producing a nice simple one.
If I go down here, you will see there is an item called Bill and
that’s the bill associated with these cell phone accounts. There
are a number of ways I can get this information into my Pivot Table.
You can click on the little box but then Excel guesses where it
thinks you want to put it. My preferred way is that you click on the
item, drag it while
holding down the button. You can see you can choose where you want
to put it- I am going to say please put it into Values. When I let
go, you’ll see what it has done is created its first little report
and this is saying that the total of that column is that amount
there. Now that itself
is not particularly useful, it is just the sum of a column which we
could do fairly easily. Now let’s introduce another item- for
example, I am going to
take this Month column, click it and drag it and now I want to do is
to see the months down the side and to have these sub-totals.
When I let go, notice that in a very easy way you have now created a
report that gives you a breakdown of the total, split by the various
months. If you don’t particularly like that or where it is placed
I can grab that label, maybe put in under the columns, when
I let go you can see it now goes across the top. And again if I want
maybe to go back, I can click it, drag it and that looks quite nice.
Another thing to
realize about Pivot Tables, is that they are not directly linked to your formula. For example if
I go and you’ll see
this is January and it is 184 and I go to the underlying data base
and I take one of the numbers – and let’s put a really big
number into the bill- let’s make it a million. When I come back to
the Pivot Table you’ll notice nothing has changed. This is because
Pivot Tables need to be told if there has been a change in the
underlying data base. Some simple ways to do this – you can either
go to the ribbon and you’ll see the button called “refresh” you
can choose to refresh or
refresh all or else you
can right click on the Pivot Table and over here you have an item
called Refresh- when I click Refresh you’ll notice that the big
number – the change I have made comes through. Let’s just undo
that and again when I want to change it I go and I click refresh and
the old number is back.
So at a very simple
level we now have a very powerful report which we can manipulate to
generate various type of reports. In the rest of the course, in the
video clips we are going to understand what can be done with each of
these sections.
