builder = aw.DocumentBuilder(doc=doc)
shape = builder.insert_chart(chart_type=aw.drawing.charts.ChartType.COLUMN, width=500, height=300)
chart = shape.chart
# Clear the chart's demo data series to start with a clean chart.
chart.series.clear()
# Add a custom series to the chart with categories for the X-axis,
# and large respective numeric values for the Y-axis.
chart.series.add(series_name='Aspose Test Series', categories=['Word', 'PDF', 'Excel', 'GoogleDocs', 'Note'], values=[1900000, 850000, 2100000, 600000, 1500000])
# Set the number format of the Y-axis tick labels to not group digits with commas.
chart.axis_y.number_format.format_code = '#,##0'
# This flag can override the above value and draw the number format from the source cell.
self.assertFalse(chart.axis_y.number_format.is_linked_to_source)
doc.save(file_name=ARTIFACTS_DIR + 'Charts.SetNumberFormatToChartAxis.docx')
