  public:

    QgsHistogramWidget( QWidget *parent /TransferThis/ = 0, QgsVectorLayer *layer = 0, const QString &fieldOrExp = QString() );
%Docstring
QgsHistogramWidget constructor. If layer and fieldOrExp are specified then the histogram
will be initially populated with the corresponding values.

:param parent: parent widget
:param layer: source vector layer
:param fieldOrExp: field name or expression string
%End

    ~QgsHistogramWidget();

    QgsVectorLayer *layer();
%Docstring
Returns the layer currently associated with the widget.

.. seealso:: :py:func:`setLayer`

.. seealso:: :py:func:`sourceFieldExp`
%End

    QString sourceFieldExp() const;
%Docstring
Returns the source field name or expression used to calculate values displayed
in the histogram.

.. seealso:: :py:func:`setSourceFieldExp`

.. seealso:: :py:func:`layer`
%End

    void setPen( const QPen &pen );
%Docstring
Sets the pen to use when drawing histogram bars. If set to Qt.NoPen then the
pen will be automatically calculated. If ranges have been set using :py:func:`~QgsHistogramWidget.setGraduatedRanges`
then the pen and brush will have no effect.

:param pen: histogram pen

Returns the pen used when drawing histogram bars.

%End

    void setBrush( const QBrush &brush );
%Docstring
Sets the brush used for drawing histogram bars. If ranges have been set using :py:func:`~QgsHistogramWidget.setGraduatedRanges`
then the pen and brush will have no effect.

:param brush: histogram brush

.. seealso:: :py:func:`brush`

Returns the brush used when drawing histogram bars.

%Docstring
Sets the graduated ranges associated with the histogram. If set, the ranges will be used to color the histogram
bars and for showing vertical dividers at the histogram breaks.

:param ranges: graduated range list

.. seealso:: :py:func:`graduatedRanges`
%End

    QgsRangeList graduatedRanges() const;
%Docstring
Returns the graduated ranges associated with the histogram. If set, the ranges will be used to color the histogram
bars and for showing vertical dividers at the histogram breaks.

:return: graduated range list

.. seealso:: :py:func:`setGraduatedRanges`

Returns the title for the histogram's x-axis.

    void setXAxisTitle( const QString &title );
%Docstring
Sets the title for the histogram's x-axis.

Returns the title for the histogram's y-axis.

  public slots:

    void refreshValues();
%Docstring
Refreshes the values for the histogram by fetching them from the layer.
%End

    void refresh();
%Docstring
Redraws the histogram. Calling this slot does not update the values
for the histogram, use :py:func:`~QgsHistogramWidget.refreshValues` to do this.

%Docstring
Sets the vector layer associated with the histogram.

:param layer: source vector layer

.. seealso:: :py:func:`setSourceFieldExp`
%End

    void setSourceFieldExp( const QString &fieldOrExp );
%Docstring
Sets the source field or expression to use for values in the histogram.

:param fieldOrExp: field name or expression string

.. seealso:: :py:func:`setLayer`
%End

  protected:

    virtual void drawHistogram();
%Docstring
Updates and redraws the histogram.
