QgsHistogramWidget constructor. If layer and fieldOrExp are specified then the histogram
will be initially populated with the corresponding values.

Returns the source field name or expression used to calculate values displayed
in the histogram.

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 setGraduatedRanges()

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.

Refreshes the values for the histogram by fetching them from the layer.

%Docstring
Redraws the histogram. Calling this slot does not update the values
for the histogram, use refreshValues() to do this.

Sets the vector layer associated with the histogram.

%Docstring
Sets the source field or expression to use for values in the histogram.
