show_leader_lines property

ChartDataLabelCollection.show_leader_lines property

Allows to specify whether data label leader lines need be shown for the data labels of the entire series. Default value is False.

@property
def show_leader_lines(self) -> bool:
    ...

@show_leader_lines.setter
def show_leader_lines(self, value: bool):
    ...

Remarks

Applies to Pie charts only. Leader lines create a visual connection between a data label and its corresponding data point.

Value defined for this property can be overridden for an individual data label with using the ChartDataLabel.show_leader_lines property.

doc = aw.Document()
builder = aw.DocumentBuilder(doc=doc)
chart = builder.insert_chart(chart_type=aw.drawing.charts.ChartType.PIE, width=500, height=300).chart
# Clear the chart's demo data series to start with a clean chart.
chart.series.clear()
# Insert a custom chart series with a category name for each of the sectors, and their frequency table.
series = chart.series.add(series_name='Aspose Test Series', categories=['Word', 'PDF', 'Excel'], values=[2.7, 3.2, 0.8])
# Enable data labels that will display both percentage and frequency of each sector, and modify their appearance.
series.has_data_labels = True
data_labels = series.data_labels
data_labels.show_leader_lines = True
data_labels.show_legend_key = True
data_labels.show_percentage = True
data_labels.show_value = True
data_labels.separator = '; '
doc.save(file_name=ARTIFACTS_DIR + 'Charts.DataLabelsPieChart.docx')
