require 'writeexcel'

workbook  = WriteExcel.new("demo2.xls")

# Add the chart extracted using the chartex utility
chart     = workbook.add_chart_ext('demo201.bin', 'Chart1')

# Link the chart to the worksheet data using a dummy formula.
worksheet.store_formula('=Sheet1!A1')

# Add some extra formats to cover formats used in the charts.

# Adjust column widths and add some headers
worksheet.set_column('A:B', 20)

worksheet.write('A1', 'Module',       bold)
worksheet.write('B1', 'No. of lines', bold)

# Add data to range that the chart refers to.
