At the beginning of the card we repeat the line for July, so that instead of showing a dot when the August figures are plotted w^e are able to draw a line showing the change which has occurred from July to August. In general, it is good practice to use one more vertical line than there are points to be plotted, so that the last point on one curve, sheet or card may be repeated on the next curve sheet or card.

Figures representing the value for each point on the curve are given immediately above each point, in the case of Fig. 205 to the nearest dollar. Figures for cents could, of course, be given if desired, but for executive purposes it is usually better to neglect the cents in all large numbers. The arrangement of the figures shown in Fig. 205 is such that at the end of the year the figures can be added cj[uickly and the total given on the card. Cards for different years can easily be looked over and the yearly total figures compared instantly, to the great advantage of the executive who has these additions made for him and recorded where they are always in plain sight. Curves as they were used in the past gave the values of single points only, without any summation for a series of points. In Fig. 205 we have not only the yearly total, but also totals for every three months, so that the total for any ciuarter of the fiscal year can be compared with the total for any other quarter.
