Inheritance diagram for KDChart::AbstractArea:Collaboration diagram for KDChart::AbstractArea:

6.1.1 Detailed Description


AbstractAreais the base class for all non-widget chart elements that have a set of background attributesand frame attributes, such as coordinate planes or axes.

Note:This class inherits fromAbstractAreaBase, AbstractLayoutItem, QObject. The reason for this trippleinheritance is that neitherAbstractAreaBasenorAbstractLayoutItemareQObject.

Inheritance diagram for KDChart::AbstractAreaBase:


Base class forAbstractAreaandAbstractAreaWidget: An area in the chart with a background, a frame, etc.

AbstractAreaBaseis the base class for all chart elements that have a set of background attributes and frameattributes, such as legends or axes.

Note:Normally you should not useAbstractAreaBasedirectly, but derive your classes fromAbstractAreaorAbstractAreaWidget.This classis not aQObject, so it is easier to inherit from it, if your are inheriting from aQObjecttoolike AbstractAreaWidgetdoes it.

Implemented inKDChart::CartesianAxis.

6.4.3.25 void AbstractAxis::setLabels (const QStringList &list)


Labels specified via setLabels take precedence: If a non-empty list is passed, KDChartwill use thesestrings as axis labels, instead of calculating them.

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

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

By default, the reference area will be set at painting time. It will be the then-valid coordinate plane’sparent widget, so normally, it will be theKDChart::Chart. Thus the labels of all of your axes in all of yourdiagrams within thatChartwill be drawn in same font size, by default.

For each dimension it will expect one column of values in the model. If the dimensionality is 1, automaticvalues will be used for the abscissa.

For example a diagram with the default dimension of 1, will have one column per datapoint (the y values)and will use automatic values for the x axis (1, 2, 3, ... n). If the dimension is 2, the diagram will use thefirst, (and the third, fifth, etc) columns as X values, and the second, (and the fourth, sixth, etc) column as Yvalues.

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

6.17.3.1 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 addyour axis to the diagram. Otherwise, there is no need to call addAxis, since the constructor does thatautomatically for you, if you pass a diagram as parameter.

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


This method gets called automatically, each time, when you assign the axis to a diagram, either by passinga 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 methodAbstractAxis::connect-Signals(), so your axis gets connected to the diagram’s built-in signals.

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


Labels specified via setLabels take precedence: If a non-empty list is passed, KDChartwill use thesestrings as axis labels, instead of calculating them.

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

By default, the reference area will be set at painting time. It will be the then-valid coordinate plane’sparent widget, so normally, it will be theKDChart::Chart. Thus the labels of all of your axes in all of yourdiagrams within thatChartwill be drawn in same font size, by default.

Inheritance diagram for KDChart::Chart:Collaboration diagram for KDChart::Chart:


A chart with one or more diagrams.

The Chartclass represents a drawing consisting of one or more diagrams and various optional elementssuch as legends, axes, text boxes, headers or footers. It takes ownership of all these elements when they areassigned to it. Each diagram is associated with a coordinate plane, of which the chart can have more thanone. The coordinate planes (and thus the associated diagrams) can be layed out in various ways.

TheChartclass makes heavy use of the Qt Interview framework for model/view programming, and thusrequires data to be presented to it in a QAbstractItemModel compatible way. For many simple charts,especially if the visualized data is static,KDChart::Widgetprovides an abstracted interface, that hides thecomplexity of Interview to a large extent.

6.20 KDChart::DataDimension Class Reference


Collaboration diagram for KDChart::DataDimension:


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

6.21 KDChart::DatasetProxyModel Class Reference

#include <KDChartDatasetProxyModel.h >

Inheritance diagram for KDChart::DatasetProxyModel:Collaboration diagram for KDChart::Dataset-ProxyModel:


DatasetProxyModeltakes aKDChartdataset configuration and translates it into a filtering proxy model.

The resulting model will only contain the part of the model that is selected by the dataset, and the accordingrow and column header data.

Currently, this model is implemented for table models only. The way it would work with models represent-ing a tree is to be decided.

The column selection is configured by passing a dataset description vector to the model. This vector (ofintegers) is supposed to have one value for each column of the original model. If the value at position x is-1, column x of the original model is not included in the dataset. If it is between 0 and (columnCount() -1),it is the column the source column is mapped to in the resulting model. Any other value is an error.

6.29.2.1 enumKDChartEnums::GranularitySequence

GranularitySequence specifies the values, that may be applied, to determine a step width within a givendata range.

Note:Granularity with can be set for Linear axis calculation mode only, there is no way to specify a stepwidth for Logarithmic axes.

Value occuring in the GranularitySequence names only are showing their respective relation ship. For realdata they will most times not be used directly, but be multiplied by positive (or negative, resp.) powers often.

A granularity sequence is a sequence of values from the following set: 1, 2, 2.5, 5.

The reason for using one of the following three pre-defined granularity sequences (instead of just using thebest matching step width) is to follow a simple rule: If scaling becomes finer (== smaller step width) novalue, that has been on a grid line before, shall loose its line and be NOT on a grid line anymore!

This means: Smaller step width may not remove any grid lines, but it may add additional lines in between.

• GranularitySequence_10_20 Step widths can be 1, or 2, but they never can be 2.5 nor 5.

• GranularitySequence_10_50 Step widths can be 1, or 5, but they never can be 2, nor 2.5.

• GranularitySequence_25_50 Step widths can be 2.5, or 5, but they never can be 1, nor 2.

• GranularitySequenceIrregular Step widths can be all of these values: 1, or 2, or 2.5, or5.

Note:When ever possible, try to avoid using GranularitySequenceIrregular! Allowing all possible step val-ues, using this granularity sequence involves a serious risk: Your users might be irritated due to ’jump-ing’ grid lines, when step size is changed from 2.5 to 2 (or vice versa, resp.).

Since you probably like having the value 1 as an allowed step width, the granularity sequence decisionboils down to a boolean question:

• To get ten divided by five you use GranularitySequence_10_20, while

• for having it divided by two GranularitySequence_10_50 is your choice.

6.29.2.2 enumKDChartEnums::MeasureCalculationMode

Measure calculation mode: the way how the absolute value of aKDChart::Measureis determined duringKD Chart’s internal geometry calculation time.

KDChart::Measurevalues either are relative (calculated in relation to a given AbstractArea), or they areabsolute (used as fixed values).

Values stored in relative measure always are interpreted as per-mille of a reference area’s height (or width,resp.) depending on the orientation set for theKDChart::Measure.

• MeasureCalculationModeAbsolute Value set by setValue() is absolute, to be used un-changed.

• MeasureCalculationModeRelative Value is relative, the reference area is specified by set-ReferenceArea(), and orientation specified by setOrientation().

• MeasureCalculationModeAuto Value is relative, KD Chart will automatically determinewhich reference area to use, and it will determine the orientation too.

• MeasureCalculationModeAutoArea Value is relative, Orientation is specified by set-Orientation(), and KD Chart will automatically determine which reference area to use.

• MeasureCalculationModeAutoOrientation Value is relative, Area is specified by set-ReferenceArea(), and KD Chart will automatically determine which orientation to use.

215 { MeasureCalculationModeAbsolute,216 MeasureCalculationModeRelative,217 MeasureCalculationModeAuto,218 MeasureCalculationModeAutoArea,219 MeasureCalculationModeAutoOrientation };

6.29.2.3 enumKDChartEnums::MeasureOrientation

Measure orientation mode: the way how the absolute value of aKDChart::Measureis determined duringKD Chart’s internal geometry calculation time.

KDChart::Measurevalues either are relative (calculated in relation to a given AbstractArea), or they areabsolute (used as fixed values).

Values stored in relative measure take into account the width (and/or the height, resp.) of a so-calledreference area, that is either specified byKDChart::Measure::setReferenceArea, or determined by KDChart automatically, respectively.



• MeasureOrientationAuto Value is calculated, based upon the width (or on the height, resp.)of the reference area: KD Chart will automatically determie an appropriate way.

• MeasureOrientationHorizontal Value is calculated, based upon the width of the referencearea.

• MeasureOrientationVertical Value is calculated, based upon the height of the referencearea.

• MeasureOrientationMinimum Value is calculated, based upon the width (or on the height,resp.) of the reference area - which ever is smaller.

• MeasureOrientationMaximum Value is calculated, based upon the width (or on the height,resp.) of the reference area - which ever is smaller.

6.29.2.5 enumKDChartEnums::TextLayoutPolicy

Text layout policy: what to do if text that is to be drawn would cover neighboring text or neighboring areas.

• LayoutJustOverwrite Just ignore the layout collision and write the text nevertheless.

• LayoutPolicyRotate Try counter-clockwise rotation to make the text fit into the space.

• LayoutPolicyShiftVertically Shift the text baseline upwards (or downwards, resp.) anddraw a connector line between the text and its anchor.

• LayoutPolicyShiftHorizontally Shift the text baseline to the left (or to the right, resp.)and draw a connector line between the text and its anchor.

Legendis drawn on chart level, not per diagram, but you can have more than one legend per chart, usingKDChart::Chart::addLegend().

Note:Legendis different from all other classes ofd KDChart, since it can be displayed outside of the Chart’sarea. If you want to, you can embedd the legend into your own widget, or into another part of a biggergrid, into which you might have inserted theChart.

On the other hand, please note that you MUST callChart::addLegendto get your legend positioned intothe correct place of your chart - if you want to have the legend shown inside of the chart (that’s probablytrue for most cases).

6.32.1.1 enumKDChart::LineAttributes::MissingValuesPolicy

MissingValuesPolicy specifies how a missing value will be shown in a line diagram.

Missing value is assumed if the data cell contains a QVariant that can not be interpreted as a double.

• MissingValuesAreBridged the default: No markers will be shown for missing values but theline will be bridged if there is at least one valid cell before and after the missing value(s), otherwisethe segment will be hidden.

• MissingValuesHideSegments Line segments starting with a missing value will not be shown,and no markers will be shown for missing values, so this will look like a piece of the line is missing.

• MissingValuesShownAsZero Missing value(s) will be treated like normal zero values, andmarkers will shown for them too, so there will be no visible difference between a zero value and amissing value.

• MissingValuesPolicyIgnored (internal value, do not use)

6.38 KDChart::Palette Class Reference

#include <KDChartPalette.h >

Inheritance diagram for KDChart::Palette:Collaboration diagram for KDChart::Palette:


A Paletteis a set of brushes (or colors) to be used for painting data sets.

The palette class encapsulates a colletion of brushes, which in the simplest case are colors, to be used forpainting a series of data sets. When asked for the m-th color, a palette of size n will wrap around and thuscycle through the available colors.

Three builtin palettes are provided for convenience, one with a default set of colors, one with a subduedcolor selection, one with rainbow colors.

When a palette changes, it emits a changed() signal. Hook up to it, if you want to repaint when the colorselection changes.

Definition at line 55 of file KDChartPalette.h.


• void addBrush(const QBrush &brush, int position=-1)

Addsbrushto the palette.

• QBrushgetBrush(int position) const

Query the palette for a brush at the specified position.

• bool isValid () const

Returns wether this represents a valid palette.

• Palette& operator=(constPalette&)• Palette(constPalette&)• Palette(QObject∗parent=0)• void removeBrush(int position)

Remove the brush at position.

• int size() const

Return the number of brushed in the palette.

• ∼Palette()


• constPalette& defaultPalette()

Set the attributes to be used for grid lines drawn in circular direction (or in sagittal direction, resp.).

To disable circular grid painting, for example, your code should like this:

GridAttributes ga = plane->gridAttributes( bool );ga.setGridVisible( false );plane-setGridAttributes( bool, ga );

Note:setGridAttributes overwrites the global attributes that were set byAbstractCoordinatePlane::setGlobal-GridAttributes. To re-activate these global attributes you can call resetGridAttributes.

6.43 KDChart::Position Class Reference

#include <KDChartPosition.h >

Collaboration diagram for KDChart::Position:


Defines a position, using compass terminology.

Using KDChartPosition you can specify one of nine pre-defined, logical points (see thestatic constgetter methods below), in a similar way, as you would use a compass to navigate on a map.

Often you will declare aPosition together with theRelativePositionclass, to specify a logical point,which then will be used to layout your chart at runtime, e.g. for specifying the location of a floatingLegendbox.

For comparing a Position’s value with a switch() statement, you can use numeric values defined inKDChartEnums, like this:

switch( yourPosition().value() ) {case KDChartEnums::PositionNorthWest:

// your code ...break;

case KDChartEnums::PositionNorth:// your code ...break;

}

See also:RelativePosition, KDChartEnums::PositionValue

#include <KDChartRelativePosition.h >


Defines relative position information: reference area, position in this area, horizontal / vertical padding,and rotating.

UsingRelativePositionyou can specify the relative parts of some position information, and you can specifythe absolute parts: the reference area, and the position in this area. To get an absolute position, you willneed to declare both, the relative and the absolute parts, otherwise the specification is incomplete and KDChartwill ignore it.
