Example:

workbook = Workbook()
# Adding a new worksheet to the Excel object
sheetIndex = workbook.getWorksheets().add()
# Obtaining the reference of the newly added worksheet by passing its sheet index
worksheet = workbook.getWorksheets().get(sheetIndex)
# Adding a sample value to "A1" cell
worksheet.getCells().get("A1").putValue(50)
# Adding a sample value to "A2" cell
worksheet.getCells().get("A2").putValue(100)
# Adding a sample value to "A3" cell
worksheet.getCells().get("A3").putValue(150)
# Adding a sample value to "B1" cell
worksheet.getCells().get("B1").putValue(4)
# Adding a sample value to "B2" cell
worksheet.getCells().get("B2").putValue(20)
# Adding a sample value to "B3" cell
worksheet.getCells().get("B3").putValue(50)
# Adding a chart to the worksheet
chartIndex = worksheet.getCharts().add(ChartType.COLUMN, 5, 0, 25, 5)
# Accessing the instance of the newly added chart
chart = worksheet.getCharts().get(chartIndex)

# Set the DataLabels in the chart
for i in range(0, chart.getNSeries().getCount()):
    datalabels = chart.getNSeries().get(i).getDataLabels()
    # Set the position of DataLabels
    datalabels.setPosition(LabelPositionType.INSIDE_BASE)
    # Show the category name in the DataLabels
    datalabels.setCategoryNameShown(True)
    # Show the value in the DataLabels
    datalabels.setShowValue(True)
    # Not show the percentage in the DataLabels
