By this method, with a consteint width to represent 100 per cent, any great change in any component affects all other components. Here the decrease in construction accidents causes the areas depicting other accidents to increase in mdth, even though there may be no increase in the actual number of accidents. Compare Fig. 131
This cut was made from specially ruled co-ordinate paper 8}/^ inches by 11 inches, with all lettering done by typewriter. The ruling as used here shows 100 per cent and three years by months. Note also Figs. 57, 103, 134 and 1.56, for which this same universal ruling has been used
