First you find the number of spaces the columns require by multiplying

the number of columns by three (5 x 3), then multiplying the number of

spaces between the columns by two (4 x 2), and adding the figures

together (15 + 8 = 23):

You use the Y-axis for the chart's scale (discussed earlier in this part

of the lesson). Again, use a scale to mark off the required number of

increments for the scale. The best scale for this chart is from 0 to

350, presented in increments of 50, and labeled dollars. The scale for

this chart requires seven equal increments (remember to maintain a 2 x 3

for the chart) (figure 1-15).

Figure 1-15.

Plotting on the Y-axis

With the spaces marked on both the X- and Y-axis, and having ensured the

chart is proportional, you finish enclosing the chart and lightly drawing

the scale lines (figure 1-16).
