The short por-tion of the line will represent the small or high pressure cylin-der, and on this length the diagram from this cylinder is con-structed from the lowest pressure, and on the longer portion ofthe line the diagram from the large cylinder is laid out. It is best however to decide on the total length of the lowpressure diagram first, and a length that can be easily dividedinto 100 parts will be found most convenient, as percentages ofthis length can then be easily measured; for example, 10 inchesfor a scale of tenths, or 12^ inches for a scale of eighths. Thecombination diagram, Fig. 113, was drawn 12j£ inches long,and photo reduced to the length shown. It now becomes necessary to decide on the scale of thespring to which the two diagrams are to be plotted; usually it 230 Steam Engine Indicator will be found most convenient for this to take the scale of thelow pressure diagram; then draw in the atmospheric, and va-,.
