#  Instantiating a Workbook object
workbook = Workbook()
#  Adding a new worksheet to the Workbook object
sheetIndex = workbook.worksheets.add()
#  Obtaining the reference of the newly added worksheet by passing its sheet index
worksheet = workbook.worksheets[sheetIndex]
#  Adding sample values to cells
worksheet.cells.get("A1").put_value(50)
worksheet.cells.get("A2").put_value(100)
worksheet.cells.get("A3").put_value(150)
worksheet.cells.get("B1").put_value(60)
worksheet.cells.get("B2").put_value(32)
worksheet.cells.get("B3").put_value(50)
#  Adding a chart to the worksheet
chartIndex = worksheet.charts.add(ChartType.COLUMN, 5, 0, 15, 5)
#  Accessing the instance of the newly added chart
chart = worksheet.charts[chartIndex]
#  Adding SeriesCollection (chart data source) to the chart ranging from "A1" cell to "B3"
chart.n_series.add("A1:B3", True)
#  Setting the title of a chart
