The first step in drawing the graph is to compute the sieve size to the 0.45 power,
using the metric sieve sizes:
Sieve Size (mm)
Sieve to the 0.45 power
Percent Passing
4.75
2.02
100
2.36
1.47
94

1.37
82
1.18
1.08

0.79

0.3
0.58

0.15
0.43

0.075
0.31

Then the x-y scatter graph function is used to plot the percent passing on the y
axis versus the sieve size to the 0.45 power:
100
90
80
70
60

Sieve size to the 0.45 power
Since the sieve size raised to the 0.45 power is not a meaningful number, the val-
ues on the axis are deleted and the text box feature is used to label the x-axis with the
actual sieve values. In addition, the drawing tool is used to add vertical lines between
the axis and the data points. The resulting graph is as follows:
