Here the scales have been properlj' arranged and the two curves appear in their correct relative position on the chart. These data, however, are not well suited for curve presentation and they are more clearly brought out by the bar method used in Fig. 87

By this method of presentation the reader may see clearly the relative length of time for different operations as well as the comparison of total time taken by the two workers. Dimension marks and figures show conveniently the actual number of seconds required. The different operations have here been given numbers instead of names. The scale to which the chart is drawn is named
