Data Computed By Dividing The Output By The Number Of Days Worked, To Obtain The Average Production Per Day, And Then Multiplying The Quotient By 303.5 Days, The Potential Number Of Working Days In A Full Year In The Anthracite Region. The Result Includes The Full-Year Capacity Of New Mines, Regardless Of When During The Year They Were Opended And Is Therefore Above The Mean Capacity For The Year.

Use a formula to modify and combine data series into a single line. For example, invert an exchange rate a by using formula 1/a, or calculate the spread between 2 interest rates a and b by using formula a - b.

Use the assigned data series variables above (e.g. a, b, ...) together with operators {+, -, *, /, ^}, braces {(,)}, and constants {e.g. 2, 1.5} to create your own formula {e.g. 1/a, a-b, (a+b)/2, (a/(a+b+c))*100}. The default formula 'a' displays only the first data series added to this line. You may also add data series to this line before entering a formula.
