# Load the Excel workbook

# Set the chart type and its position on the worksheet.

# Add the series to the chart
# The first parameter represents the address of the range for the horizontal(category) axis.
# The second parameter represents the address of the range for the vertical(value) axis.
series = chart.AddSeries("B3:B8", "A3:A8")

# Set the chart title.
series.Title = "Line Chart"

# Set the legend position.
# Can be removed by setting it to None.
chart.SetLegendPosition(LegendPosition.Bottom)

# We can change the position of the chart.
chart.Position.LeftColumnIndex = 2
chart.Position.RightColumnIndex = chart.Position.LeftColumnIndex + 3

# Plot all the data that was added to the chart before.
# Multiple calls to this method lead to plotting multiple charts instead of modifying the existing chart.
# Yet there is no possibility to remove a chart or edit its series/position.
# We can just create a new one.
chart.Plot()

# Save changes with the created line chart
