Expression List The expression list in the top-left pane is a complete tree control with numerous
control options.
In front of each expression (or expression group) an expansion icon (a box
with a ' + ' ) is shown. Clicking the icon opens up underlying sub-expressions
or attribute expressions. The icon is simultaneously replaced by a collapse
icon ( ' - ' ). Certain plot options utilize sub-expressions, i.e. a set of two or
more expressions that together define the plot symbol (e.g. Stock or Box Plot
described below).
Expression data can also be dynamically formatted by means of attribute
expressions. Click on the expansion icon in front of any expression to display
the placeholders for the dimension’s attribute expressions. These are:

Background Color
Edit the default Background Color expression to create the attribute expression
for calculating the plot color of the data point. The calculated color will
have precedence over the default QlikView color selection and must be a
valid color representation, which is achieved by using the Color Functions
(page 361). If the result of the expression is not a valid color representation,
the program will default to black. An auxiliary expression for Text Color can
be created using the same method.
Text Color
An auxiliary expression for Text Color can be created using the same method
as for the background color (see above).
Text Format
Edit the Text Format expression to enter an attribute expression for calculating
the font style of text associated with the data point (For tables: text in
the table cell for each dimension cell. The calculated text format will have
precedence over table style defined in the Chart Properties: Style (page 735).)
The expression used as text format expression should return a string containing
a '' for bold text, '' for italic text and/or '' for underlined text. Note
that = is necessary before the string.
Pie Popout
Click on the Pie Popout in order to enter an attribute expression for calculating
whether the pie slice associated with the data point should be drawn
in an extracted "popout" position. This type of attribute expression only has
effect on pie charts.
Bar Offset
Click on Bar Offset in order to enter an attribute expression for calculating an
offset for the bar or bar segment associated with the data point. The offset can
be positive or negative and will move the bar or segment accordingly. This is
useful e.g. when making so called waterfall charts. This type of attribute
expression only has effect on bar charts.
Line Style
Click on Line Style in order to enter an attribute expression for calculating the
line style for the line or line segment associated with the data point. This type
of attribute expression only has effect on line, combo and radar charts.
