CHARTCOLUMN Properties

Basic
property

Each item of a chart represents one line. Each line holds as information (1) the text of the line and (2) multiple key figures that are the values to be rendered as line. E.g. a line may have the values "region,revenue,cost,profit". In this case the "region" is the element passing the text of the line, whereas the other elements are passing the key figure information. For each element you maintain one CHARTCOLUMN item, each one pointing to the data element that passes the value at runtime.

Obligatory  
xaxisproperty

This is an indicator of the attribute "PROPERTY" is holding a text value (then "true") or a key figure value (then "false"). In the example of a line "region,revenue,cost,profit" the corresponding XAXISPROPERTY would be "true,false,false,false".

Optional

true

false

title

The text shown for this item as corresponding title on the xaxis. If no title is specified then the property name (see property above) is used as xaxis title.

Optional  
titleprop

The name of the adapter parameter which provides the title.

Optional
