Series Is Presented Here As Two Variables--(1)--Original Data, 1890-1944 (2)--Original Data, 1890-1961. Data Are For The Calculated 308-Day Capacity Of All Mines That Operate For Any Part Of The Yeaar, Including New Mines. Data Found In Source On Basis Of 280 Work Days A Year. Estimates Have Nothing To Do With Known Reserves, But Simply Represent Potential Production For An Arbitrarily Chosen Number Of Days Per Year. This Series Is Reprinted In Mineral Yearbook, 1945, P.834 On The Basis O Of 280 Working Days, And 261 Working Days (5-Day Work Week) A 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.
