value <...value-n>
creates ticks for specific values. For example, VALUES=(0 50 100) places
tick marks at 0, 50, and 100.
value-1 TO value-2 BY increment-value
creates ticks for a range of values. The start of the value range is specified by
value-1 and the end of the range is specified by value-2. The increment-value
specifies the interval between the ticks. For example, VALUES=(0 to 100
by 50) creates tick marks at 0, 50, and 100.
Note: If you omit the increment-value, the procedure generates the first tick
value, but does not increment beyond that value. The result can be
unpredictable output.
