Detailed Description¶

A pie series consists of slices that are defined as QPieSlice objects. The slices can have any values as the QPieSeries object calculates the percentage of a slice compared with the sum of all slices in the series to determine the actual size of the slice in the graph.

Pie size and position on the graph are controlled by using relative values that range from 0.0 to 1.0. These relate to the actual graph rectangle.

By default, the pie is defined as a full pie. A partial pie can be created by setting a starting angle and angle span for the series. A full pie is 360 degrees, where 0 is at 12 a’clock.

Note

Properties can be used directly when from __feature__ import true_property is used or via accessor functions otherwise.

property countᅟ: int¶

This property holds The number of slices in the series..

Access functions:

count()
Signal countChanged()

property endAngleᅟ: float¶

This property holds The ending angle of the pie..

A full pie is 360 degrees, where 0 degrees is at 12 o’clock.

The default value is 360.

Access functions:

pieEndAngle()
setPieEndAngle()

property holeSizeᅟ: float¶

This property holds The donut hole size..

When setting the pieSize property, this property is adjusted if necessary, to ensure that the hole size is not greater than the pie size.

The default value is 0.0.

Access functions:

holeSize()
setHoleSize()

property horizontalPositionᅟ: float¶

This property holds The horizontal position of the pie..

The value is relative to the graph rectangle, so that:

0.0 is the absolute left.

1.0 is the absolute right.

The default value is 0.5 (center).

See also

verticalPosition

Access functions:

horizontalPosition()
setHorizontalPosition()

property sizeᅟ: float¶

Access functions:

pieSize()
setPieSize()

property startAngleᅟ: float¶

This property holds The starting angle of the pie..

A full pie is 360 degrees, where 0 degrees is at 12 o’clock.

The default value is 0.

Access functions:

pieStartAngle()
setPieStartAngle()

property sumᅟ: float¶

This property holds The sum of all slices..

The series keeps track of the sum of all the slices it holds.

Access functions:

sum()
Signal sumChanged()

property verticalPositionᅟ: float¶

This property holds The vertical position of the pie..

The value is relative to the graph rectangle, so that:

0.0 is the absolute top.

1.0 is the absolute bottom.

The default value is 0.5 (center).

horizontalPosition

Access functions:

verticalPosition()

__init__([parent=None])¶

Parameters:: parent – QObject

Constructs a series object that is a child of parent.

clear()¶

Clears all slices from the series.

count()¶

Return type:: int

Returns the number of the slices in this series.

Getter of property countᅟ .

countChanged()¶

Notification signal of property countᅟ .
