Help <F1> Is Your Friend

Formulae List Separators

List separators shown in Help are semi-colons, but commas are now the default. Tools|Options|LibreOffice|Calc|Formula

Summing Columns 1

This is one way to sum a column of numbers.

Summing Columns 2

There are other ways to sum a column of numbers:

=SUM(A1,A3,B5) specific cells

=SUM(C1:C5) specified range

=SUM(A19:B21) specified range

Sort Lists

It is easy to drag and fill a series of numbers.

This can be extended to strings or words.

Type one piece of information in a cell, then drag it to fill in a consecutive list of items

See Tools|Options|LibreOffice| Calc|Sort Lists to create your own

Sorting by Columns

It is easy to sort blocks of data.

Select area, including headings.

Click Data|Sort…

Sort by ‘Rating’ descending and ‘Cost’ ascending.

Click OK.

Change Icon Size

● Click on Tools|Options...|LibreOffice|View● Select Toolbar icon size

Selecting Toolbars

● Select View|Toolbars|Form Controls

● The toolbar can now be dragged to anywhere

● Now you have access to conveniently grouped functions

Named Ranges

● Ranges are defined as (say) d20:g40

● They can also be given aname to use in formulae

● Select the range● Select Data|Define Range…● Provide a name● Click Add● Now use it in formulae

Hlookup and Vlookup 2

Rating Cost Item

5 23 Pear Enter rating

4

5 78 Apple Cost 56

4 56 Orange Item Orange

4 98 Pineapple

Search term Lookup values

Hlookup and Vlookup 1

● Here is a Vlookup example● H19 holds the search term - ‘4’● Vegetables is the named range of the table● The numerals 2 and 3 are the offsets to the

answers● The zeros indicate that the column is not in

ascending order● Cost: =VLOOKUP(H19,Vegetables,2,0)● Item: =VLOOKUP(H19,Vegetables,3,0)

Text Boxes

● Text boxes do not move like cells, or affect column widths.

● They can be formatted.

My text box. It stays where I put it.

It does not move like a cell does.

It can be formatted.It can be formatted.

Linking Data to Graphs

Enter some data.

Select Insert|Chart

Work through ● Chart Type● Data Range● Data Series● Chart Elements

Data Constraints 1

● Sometimes you need to restrict the entry to a field to certain values

● Examples are:– A range of dates

– “Y” or “N”

● The easiest way is to select the cell and then select Data|Validity to set the constraints.

● We have two examples.

Data Constraints 2

● “Y” or “N” example● Clicking on the cell displays

an arrow button andoffers two choices

● Select the cell andthen click on Data|Validity

● Enter the values and help

● Select text example● In this case a range of

dates from other cells● The worksheet is

$Actual● The cells are

$E$45:$E$48● Tip: place two

spaces before the full stop on thehelp caption

Data Constraints 3

Conditions – If This Then ...

● We sometimes need to change a formula, depending on another cell’s content.

● =IF(condition, do this if true, do this if false)● =IF(F9<=F11,"Valid Date","Invalid Date")● =IF($C$7="","Enter name in cell",$C$7)

Concatenate

● Joining strings together● CONCATENATE("Text1", "Text2", …)● CONCATENATE(“The result: “, B10, …)● More advanced:● Enter “Name” into cell C7● Enter the following into C8, C9, C10● =CONCATENATE(IF($C$7="","Nobody ",$C$7),"

has a birthday")

Nested Formulae

● IF(…..), OR(….), AND(….), CONCATENATE(….) etc can all be nested.

● Consider:● =CONCATENATE($C$6)," Dances: ")● What if $C$6 is blank?● Add a condition:● =CONCATENATE(IF($C$6="","Nobody",

$C$6)," Dances: ")

Truth Tables

● Making sure logic is correct can be a bit tricky● Use a truth table to check● =IF(A=”T”,IF(B=”T”,Result 1,Result 2),IF(B=”T”,

Result 3,Result 4))● Note the nesting of the

conditions

A B Result

T T Result 1

T F Result 2

F T Result 3

F F Result 4

Comparison Operators

Symbol Operator

= Equals

>= Greater than or equal to

<= Less than or equal to

<> Not equal to

Conditional Formatting

● Change cell colours to indicate an error● Click on Formatting|Conditional Formatting|

Condition● Multiple conditions can be set

Conditional Formatting 2

● Conditional formatting may depend on two conditions

● IF(AND(J10="N"),(K10="Y"))

● Cell contents: =IF($J10="N","SIPP (not left in will)",IF(K10="Y","SIPP (left to spouse)","SIPP (left to third party)"))
