Detailed Description

A set of attributes controlling the appearance of data set markers.

Member Enumeration Documentation

enum KChart::MarkerAttributes::MarkerSizeMode

Enumerator
AbsoluteSize	the marker size is directly specified in pixels
AbsoluteSizeScaled	the marker size is specified in pixels, but scaled by the painter's zoom level
RelativeToDiagramWidthHeightMin	the marker size is relative to the diagram's min(width, height)

Member Function Documentation

void MarkerAttributes::setMarkerSize

(

const QSizeF &

size

)

Normally you need to specify a valid QSizeF here, but for Legends you can use the invalid size QSizeF(), to enable automatic marker size calculation:

For Markers shown in a Legend this means the marker size will be equal to the font height used for the labels that are shown next to the markers.

void MarkerAttributes::setMarkerSizeMode

(

MarkerSizeMode

mode

)

With this method you can change the way the actual marker size is calculated.

By default, the marker size is absolute (equiv. to mode = AbsoluteSize) and specifies the size in pixels.

In any other case, the size specified will be relative to what is specified in mode, e.g. the diagram's width. A marker width or height of 1.0 is then 100% of the diagram's width.

void MarkerAttributes::setMarkerStyle

(

uint

style

)

Set the marker-style to use.

This could be either one of the predefined MarkerStyle or a custom one that has a value bigger or equal to StartCustomMarkers.

Such a custom marker does then allow to fetch a custom pixmap for each point (value pair) from the model using the Qt::DecorationRole .
