class ooodev.adapter.chart.chart_data_partial.ChartDataPartial(component, interface=com.sun.star.chart.XChartData)[source]

Bases: object

Partial class for XChartData.

Parameters:

  • component (XChartData) –

  • interface (UnoInterface | None) –

__init__(component, interface=com.sun.star.chart.XChartData)[source]

The component will be notified with a ChartDataChangeEvent every time the chart’s data changes.

Return type:

None

Parameters:

listener (com.sun.star.chart.XChartDataChangeEventListener) –

get_not_a_number()[source]

In IEEE arithmetic format it is one of the NaN values, so there are no conflicts with existing numeric values.

Return type:

float

is_not_a_number(number)[source]

checks whether the value given is equal to the indicator value for a missing value.

In IEEE arithmetic format it is one of the NaN values, so there are no conflicts with existing numeric values.

Always use this method to check, if a value is not a number. If you compare the value returned by XChartData.getNotANumber() to another double value using the = operator, you may not get the desired result!

Return type:

bool

Parameters:

number (float) –

remove_chart_data_change_event_listener(listener)[source]

Removes a previously registered listener.

Return type:
