Pivot Tables 2007 Values
We are now going to
look in a little more
detail at the Values
Portion– where the data is generally kept. Just
a couple of useful bits
of information upfront.
As you can see we
have pulled through the Bill Column and you’ll see it has told us
“Sum of Bill”. If you want you can pull the Bill Column through
many times
- you’ll see I’ve grabbed it once, grab it twice and as
you can see the exact same information comes through and we’ll
show you later why this is useful. Also note that the Column Labels
now has something
called Values- if you watch what happens here on the screen if I
grab that and drag it and put it underneath the month and let go -
notice that the Value headers now follow after the month. If I
don’t like that , grab it and move it above the month, let go –
now the Value header sits here with the month underlying it. I am
just going to put it back there.
Now let’s see what
else we can do with the Values Portion.
If you click on one
of the numbers, and
you right click, you’ll see you get a number of options
but at the bottom here there is something
called Value Field Settings. If
I click on it, you get the following options – just working
through it- you’ll see at the top
is Custom Name. If
you don’t like the name Excel has given it you can type you own
name in. You’ll also notice that at the bottom there is something
called Number Format. Let’s
just cancel out of here. If you look at this data you may be tempted
to format the data here
in the normal way perhaps right click Format cells and then go and
do some formatting. You
need to realize that Pivot Tables stand on their own so if you try
to format the cells straight into the Spreadsheet, next time you
refresh that formatting may be lost. As a result the only way to
format it properly is to go to Value Field Settings and Click on
Number Format and you’ll see the exact same dialogue box appears
but now when you choose the settings you can see although you
highlighted one cell and click on OK you’ll see that entire
Value Column gets formatted because the Pivot Table knows that you
want all those items to be formatted exactly the same.
Let’s just click
on this one here and go back into our Value Field Settings and
let’s look now at the Summarised Value Field by. You’ll see when
we drag the Value Field into the Values item it immediately assumed
that you want to sum the
information in that column. However there are a number of other
options eg you could count the number of items. If I click Count and
I say OK you’ll see it
tells me how many items it found and you’ll see there were 58
items which added up to the R184.
If I right click again, Value Field Settings – perhaps I
want to look at the Average. I click Average and say OK you can see
that what it is telling me is on average for the 58 items previously
identified at 184, the average was 3.17. Let’s see what the other
options are – there is a Max – it brings through the maximum
number it finds in those
areas, there is a minimum, shows the minimum number. And you will
see there are other options – product (counts how many numbers it
found), there is a standard
deviation and a few other statistical terms.
Just going back here
– let’s put it back to sum. Now let’s look at the
“Show Values As” Tab .
When I click on that
you’ll see it says Show Values As – currently it is at
Normal – so what it is doing is just showing the normal
values. If I click on this a whole bunch of options appear –
you’ll see there is a difference from, percentage of, running
total in, and a number of other options.
So let’s just look
at these- let’s go to the first one – difference from : when you
activate this option you’ll see it asks you what the base field is
and what the base item is. Now what does that mean? When we look at
this table you’ll see we have
got January, February, March. I want to see the difference
from, in this case, the
previous month so over here I want to see what the difference is
between those two and over here the difference between those two. In
order to activate that I have to tell Excel what the base field is
– I say please go and use the month. And then for base item I can
either say look at the previous item (so February will look at
January), or next (so January will look at February) or
I can specify a particular month so if I say January, not only will
this one show the difference from January, but March will
also show the difference from January. So I am going to say
go to Previous and when
I say OK you’ll see what you have got now is a difference from the
previous month so this
number is 953 more than January and this number is 222 less.
Let’s continue to
explore these options. So
I right click Value Field Settings; Show Value As; currently we are
on difference from. Let’s go to the next one which is percentage
of: when I click on it , again you have the option of base field –
the base field needs to be in your Pivot Table otherwise it will
give you an error message, so
we leave it on Month and in this case let’s rather use our base
item as February so it seems February is the highest number so we
are now going to compare everything to February. When I say OK
you’ll see it gives me a percentage of February’s total – so
that number is 16% of February, this (February)
is 100% of February and
that is 80% of February. Going back here – let’s go to Value
Field Settings; Show Value As: you’ll see the next item is
Percentage difference from: which is pretty much similar to
the difference
from and the percentage
of it just puts the difference from in percentage terms so we’ll
ignore that one for now. There is another item here called Running
Total In: when I click on it, all
it wants to know is where must it run the total from- which
means that we want to have a running total in this column so January
will be 184, February will add these two together and March will add
all three together. So it can be a year to date type
situation. When I say OK you’ll see what it has done is January is
the starting point, February adds the two numbers together, March
adds all three numbers together and you don’t have a grand total
because this is a running total and there is the total for those
three items.
Let’s look at
some of the other options. So we are currently in Running
Total In: you’ll see over here we have got
a percentage of row, percentage of column or percentage of
total. Just moving this down – at the moment you’ll see
percentage of row would give me what percent this makes of the row
but we don’t have a sub-total here. We have got percentage of
column so we want to know what percent does that number make of this
entire column – basically of the total. So if I go to percentage
of column and I say OK you’ll see it will always add up to 100%.
The first item is 8% of the total, the second one is 50%
etc. That is similar to this item here, percentage of total
– if you have multiple rows and columns. What the percentage will
be - it will be a percentage of the grand total of all rows and
columns. And the last
item is Index which
helps you to calculate the relative value of a cell. It
can be useful - it is best to look at the Help file to
understand how it does that calculation.
The last thing to
understand about the Value section – let’s say we look at this
number here – we see that it is 915.52. Now it is very difficult
to understand what that number is made up of – if we had to come
here we would have to look
through the entire data base to figure it out. What you can do as
well is if I simply double click any particular cell – so I am
going to double click this one. What you will see is that it has
opened another sheet and it has extracted all the items from the
data base that make up that number- so if we had to come to the bill
and we add it up
you’ll see it comes to the 915 – we can now look at this and
understand what makes up that particular component. So again, just
to show you, choose a cell you want to work with, double click it
and the information will be extracted for you.
