Detailed Description

The class for cartesian axes.

For being useful, axes need to be assigned to a diagram, see AbstractCartesianDiagram::addAxis and AbstractCartesianDiagram::takeAxis.

Constructor & Destructor Documentation

CartesianAxis::CartesianAxis ( AbstractCartesianDiagram diagram = 0  )  [explicit]

C'tor of the class for cartesian axes.

Note:
If using a zero parent for the constructor, you need to call your diagram's addAxis function to add your axis to the diagram. Otherwise, there is no need to call addAxis, since the constructor does that automatically for you, if you pass a diagram as parameter.

This is called at layout time by KDChart:AutoSpacerLayoutItem::sizeHint().

The method triggers AbstractArea::sizeHint() to find out the amount of overlap at the bottom edge of the area.

Note:
The default implementation is not using any caching, it might make sense to implement a more sophisticated solution for derived classes that have complex work to do in sizeHint(). All we have here is a primitive flag to be set by the caller if it is sure that no sizeHint() needs to be called.

void AbstractAxis::connectSignals (  )  [virtual, inherited]

Wireing the signal/slot connections.

This method gets called automatically, each time, when you assign the axis to a diagram, either by passing a diagram* to the c'tor, or by calling the diagram's setAxis method, resp.

If overwriting this method in derived classes, make sure to call this base method AbstractAxis::connectSignals(), so your axis gets connected to the diagram's built-in signals.

void AbstractAxis::createObserver ( AbstractDiagram diagram  )  [inherited]
const QString AbstractAxis::customizedLabel ( const QString &  label  )  const [virtual, inherited]

Implement this method if you want to adjust axis labels before they are printed.

KD Chart is calling this method immediately before drawing the text, this means: What you return here will be drawn without further modifications.

Parameters:
label The text of the label as KD Chart has calculated it automatically (or as it was taken from a QStringList provided by you, resp.)
Returns:
The text to be drawn. By default this is the same as label.

void CartesianAxis::setAnnotations ( const QMap< double, QString > &  annotations  )

Annotations are a QMap of doubles and QStrings defining special markers and their position. If you use annotations, the normal ticks and values will be invisible. To unset the annotations, pass an empty QMap.

void AbstractAxis::setLabels ( const QStringList &  list  )  [inherited]

Use this to specify your own set of strings, to be used as axis labels.

Labels specified via setLabels take precedence: If a non-empty list is passed, KD Chart will use these strings as axis labels, instead of calculating them.

If you a smaller number of strings than the number of labels drawn at this axis, KD Chart will iterate over the list, repeating the strings, until all labels are drawn. As an example you could specify the seven days of the week as abscissa labels, which would be repeatedly used then.

By passing an empty QStringList you can reset the default behaviour.

Inform the item about its widget: This enables the item, to trigger that widget's update, whenever the size of the item's contents has changed.

Thus, you need to call setParentWidget on every item, that has a non-fixed size.

Every axis has a default set of ruler attributes that is exactly the same among them. Use this method to specify your own attributes.

void AbstractAxis::setShortLabels ( const QStringList &  list  )  [inherited]

Use this to specify your own set of strings, to be used as axis labels, in case the normal labels are too long.

Note:
Setting done via setShortLabels will be ignored, if you did not pass a non-empty string list via setLabels too!

By passing an empty QStringList you can reset the default behaviour.

void AbstractAxis::setTextAttributes ( const TextAttributes a  )  [inherited]

Use this to specify the text attributes to be used for axis labels.

By default, the reference area will be set at painting time. It will be the then-valid coordinate plane's parent widget, so normally, it will be the KDChart::Chart. Thus the labels of all of your axes in all of your diagrams within that Chart will be drawn in same font size, by default.
