Python Matplotlib: Create chart for every 4 columns in Excel file

[JaneTan]

Hi

I want to use Mathplotlib for it. Basically, it should loop through every 4 columns in my Excel file and create a separate graph for every 4 column

Every 4 columns will be the Revenue, Cost, Wage and Profit for a firm. The graph for each firm will have the 4 lines for Revenue, Cost, Wage and Profit

Thank you
