[virtual] QAbstractBarSeries::~QAbstractBarSeries()

Destructs abstractbarseries and owned barsets.

bool QAbstractBarSeries::append(QBarSet *set)

Adds a set of bars to series. Takes ownership of set. If the set is null or is already in series, it won't be appended. Returns true, if appending succeeded.

bool QAbstractBarSeries::append(QList<QBarSet *> sets)

Adds a list of barsets to series. Takes ownership of sets. Returns true, if all sets were appended successfully. If any of the sets is null or is already appended to series, nothing is appended and function returns false. If any of the sets is in list more than once, nothing is appended and function returns false.

QList<QBarSet *> QAbstractBarSeries::barSets() const

Returns a list of sets in series. Keeps ownership of sets.

qreal QAbstractBarSeries::barWidth() const

Returns the width of the bars of the series.

Note: Getter function for property barWidth.

See also setBarWidth().

[signal] void QAbstractBarSeries::barsetsAdded(QList<QBarSet *> sets)

This signal is emitted when sets have been added to the series.

See also append() and insert().

[signal] void QAbstractBarSeries::barsetsRemoved(QList<QBarSet *> sets)

This signal is emitted when sets have been removed from the series.

See also remove().

void QAbstractBarSeries::clear()

Removes all barsets from the series. Deletes removed sets.

[signal] void QAbstractBarSeries::clicked(int index, QBarSet *barset)

The signal is emitted if the user clicks with a mouse on top of QBarSet barset. Clicked bar inside set is indexed by index

int QAbstractBarSeries::count() const

Returns number of sets in series.

Note: Getter function for property count.

[signal] void QAbstractBarSeries::countChanged()

This signal is emitted when barset count has been changed, for example by append or remove.

Note: Notifier signal for property count.

[signal] void QAbstractBarSeries::doubleClicked(int index, QBarSet *barset)

The signal is emitted if the user doubleclicks with a mouse on top of QBarSet barset. DoubleClicked bar inside set is indexed by index

[signal] void QAbstractBarSeries::hovered(bool status, int index, QBarSet *barset)

The signal is emitted if mouse is hovered on top of series. Parameter barset is the pointer of barset, where hover happened. Parameter status is true, if mouse entered on top of series, false if mouse left from top of series. Hovered bar inside the set is indexed by index.

bool QAbstractBarSeries::insert(int index, QBarSet *set)

Insert a set of bars to series at index postion. Takes ownership of set. If the set is null or is already in series, it won't be appended. Returns true, if inserting succeeded.

bool QAbstractBarSeries::isLabelsVisible() const

Returns the visibility of labels

Note: Getter function for property labelsVisible.

[signal] void QAbstractBarSeries::labelsAngleChanged(qreal angle)

Signal is emitted when the angle of the value labels is changed.

Note: Notifier signal for property labelsAngle.

[signal] void QAbstractBarSeries::labelsFormatChanged(const QString &format)

Signal is emitted when the format of data value labels is changed.

Note: Notifier signal for property labelsFormat.

[signal] void QAbstractBarSeries::labelsPositionChanged(QAbstractBarSeries::LabelsPosition position)

Signal is emitted when the position of value labels is changed.

Note: Notifier signal for property labelsPosition.

[signal] void QAbstractBarSeries::labelsVisibleChanged()

This signal is emitted when labels visibility have changed.

Note: Notifier signal for property labelsVisible.

See also isLabelsVisible() and setLabelsVisible().

[signal] void QAbstractBarSeries::pressed(int index, QBarSet *barset)

The signal is emitted if the user presses with a mouse on top of QBarSet barset. Pressed bar inside set is indexed by index

[signal] void QAbstractBarSeries::released(int index, QBarSet *barset)

The signal is emitted if the user releases with a mouse on top of QBarSet barset. Released bar inside set is indexed by index

bool QAbstractBarSeries::remove(QBarSet *set)

Removes barset from series. Releases ownership of set. Deletes the set, if remove was successful. Returns true, if set was removed.

void QAbstractBarSeries::setBarWidth(qreal width)

Sets the width of the bars of the series. The unit of width is the unit of x-axis. The minimum width for bars is zero and negative values are treated as zero. Setting the width to zero means that width of the bar on screen is one pixel no matter what the scale of x-axis is. Bars wider than zero are scaled with x-axis. Note that with this value means the width of one group of bars instead of just one bar.

Note: Setter function for property barWidth.

See also barWidth().

void QAbstractBarSeries::setLabelsVisible(bool visible = true)

Sets the visibility of labels in series to visible

Note: Setter function for property labelsVisible.

See also isLabelsVisible().

bool QAbstractBarSeries::take(QBarSet *set)

Takes a single set from the series. Does not delete the barset object.

NOTE: The series remains as the barset's parent object. You must set the parent object to take full ownership.

Returns true if take was successful.
