List of all members.

## Detailed Description

Helper class for one dimension of data, e.g. for the rows in a data model, or for the labels of an axis, or for the vertical lines in a grid.

isCalculated specifies whether this dimension's values are calculated or counted. (counted == "Item 1", "Item 2", "Item 3" ...)

sequence is the GranularitySequence, as specified at for the respective coordinate plane.

Step width is an optional parameter, to be omitted (or set to Zero, resp.) if the step width is unknown.

The default c'tor just gets you counted values from 1..10, using step width 1, used by the CartesianGrid, when showing an empty plane without any diagrams.

## Member Function Documentation

qreal KDChart::DataDimension::distance | ( |  | ) | const

Returns the size of the distance, equivalent to the width() (or height(), resp.) of a QRectF.

Note that this value can be negative, e.g. indicating axis labels going in reversed direction.
