int AbstractArea::bottomOverlap ( bool  doNotRecalculate = false  )  const [virtual, inherited]

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.

KDChart::DataDimensionsList KDChart::AbstractCoordinatePlane::gridDimensionsList (  )  [inherited]

Returns the dimensions used for drawing the grid lines.

Returned data is the result of (cached) grid calculations, so - if you need that information for your own tasks - make sure to call again this function after every data modification that has changed the data range, since grid calculation is based upon the data range, thus the grid start/end might have changed if the data was changed.

Note:
Returned list will contain different numbers of DataDimension, depending on the kind of coordinate plane used. For CartesianCoordinatePlane two DataDimension are returned: the first representing grid lines in X direction (matching the Abscissa axes) and the second indicating vertical grid lines (or Ordinate axes, resp.).
Returns:
The dimensions used for drawing the grid lines.

AbstractCoordinatePlane * KDChart::AbstractCoordinatePlane::referenceCoordinatePlane (  )  const [inherited]

There are two ways, in which planes can be caused to interact, in where they are put layouting wise: The first is the reference plane.

If such a reference plane is set, on a plane, it will use the same cell in the layout as that one. In addition to this, planes can share an axis. In that case they will be laid out in relation to each other as suggested by the position of the axis. If, for example Plane1 and Plane2 share an axis at position Left, that will result in the layout: Axis Plane1 Plane 2, vertically. If Plane1 also happens to be Plane2's reference plane, both planes are drawn over each other. The reference plane concept allows two planes to share the same space even if neither has any axis, and in case there are shared axis, it is used to decided, whether the planes should be painted on top of each other or laid out vertically or horizontally next to each other.

Returns:
The reference coordinate plane associated with this one.

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 CartesianCoordinatePlane::setAutoAdjustHorizontalRangeToData ( unsigned int  percentEmpty = 67  ) 

Automatically adjust horizontal range settings to the ranges covered by the model's values, when ever the data have changed, and then emit horizontalRangeAutomaticallyAdjusted.

By default the horizontal range is adjusted automatically, if more than 67 percent of the available horizontal space would be empty otherwise.

Range setting is adjusted if more than percentEmpty percent of the horizontal space covered by the coordinate plane would otherwise be empty. Automatic range adjusting can happen, when either all of the data are positive or all are negative.

Set percentEmpty to 100 to disable automatic range adjusting.

Parameters:
percentEmpty The maximal percentage of horizontal space that may be empty.

void CartesianCoordinatePlane::setHorizontalRange ( const QPair< qreal, qreal > &  range  ) 

Set the boundaries of the visible value space displayed in horizontal direction.

This is also known as the horizontal viewport.

By default the horizontal range is adjusted to the range covered by the model's data, see setAutoAdjustHorizontalRangeToData for details. Calling setHorizontalRange with a valid range disables this default automatic adjusting, while on the other hand automatic adjusting will set these ranges.

To disable use of this range you can either pass an empty pair by using the default constructor QPair() or you can set both values to the same which constitutes a null range.

Note:
By default the visible data range often is larger than the range calculated from the data model (or set by setHoriz.|Vert.Range(), resp.). This is due to the built-in grid calculation feature: The visible start/end values get adjusted so that they match a main-grid line. You can turn this feature off for any of the four bounds by calling GridAttributes::setAdjustBoundsToGrid() for either the global grid-attributes or for the horizontal/vertical attrs separately.
If you use user defined vertical ranges together with logarithmic scale, only positive values are supported. If you set it to negative values, the result is undefined.
Parameters:
range a pair of values representing the smalles and the largest horizontal value space coordinate displayed.
