-0.7 (ÿ) -0.4 (ÿ) 6 (ÿ)
Make the values for the Intervals fields fit to the difference of the values for the Minimum and
the Maximum fields. For example, 6 intervals for a horizontal range of length 0.3 (= difference of
-0.7 and -0.4) ensures nice numbers below the tick marks.
-0.01 (ÿ) 0.01 (ÿ) 4 (_OK_)
