-B<[--step E<lt>secondsE<gt>]>
+B<[-S|--step E<lt>secondsE<gt>]>
The start and end of what you would like to display, and which
B<RRA> the data should come from. Defaults are: 1 day ago until
--maximum-upper-limit 4000 --minimum-upper-limit 4000
--maximum-lower-limit -3000 --minimum-lower-limit -3000
-B<[--alt-autoscale]>
+B<[-A|--alt-autoscale]>
Sometimes the default algorithm for selecting the y-axis scale is not
performing very well. Normally the scale is selected from a predefined
would display slightly less than C<260-0.001> to slightly more than
C<260+0.001> (Contributed by Sasha Mikheev).
-B<[--alt-autoscale-max]>
+B<[-M|--alt-autoscale-max]>
Where C<--alt-autoscale> will modify both the absolute maximum AND minimum
values, this option will only affect the maximum value. The minimum
be useful when graphing router traffic when the WAN line uses compression,
and thus the throughput may be higher than the WAN line speed.
-B<[--no-gridfit]>
+B<[-N|--no-gridfit]>
To avoid antialiasing effects gridlines are placed on
integer pixel values. This is by default done by extending
skip the grid and labels altogether. The default for this option is
to automatically select sensible values.
-B<[--alt-y-grid]>
+B<[-Y|--alt-y-grid]>
Place Y grid dynamically based on graph Y range. Algorithm ensures
that you always have grid, that there are enough but not too many
Logarithmic y-axis scaling.
-B<[--units-exponent E<lt>valueE<gt>]>
+B<[-X|--units-exponent E<lt>valueE<gt>]>
This sets the 10**exponent scaling of the y-axis values. Normally
values will be scaled to the appropriate units (k, M, etc.). However
