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 Yaxis 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 115).
Figure 115. Plotting on the Yaxis
With the spaces marked on both the X and Yaxis, and having ensured the
chart is proportional, you finish enclosing the chart and lightly
drawing the scale lines (figure 116).
