[B<-N>|B<--no-gridfit>]
-In order to avoid anti-aliasing effects gridlines are placed on
-integer pixel values. This is by default done by extending
-the scale so that gridlines happens to be spaced using an
-integer number of pixels and also start on an integer pixel value.
-This might extend the scale too much for some logarithmic scales
-and for linear scales where B<--alt-autoscale> is needed.
-Using B<--no-gridfit> disables modification of the scale.
+In order to avoid anti-aliasing blurring effects rrdtool snaps
+points to device resolution pixels, this results in a crisper
+aperance. If this is not to your liking, you can use this switch
+to turn this behaviour off.
+
+Gridfitting is turned off for PDF, EPS, SVG output by default.

and labels every 4 hours. The labels are placed under the major grid
lines as they specify exactly that time.
- --x-grid HOUR:8:DAY:1:DAY:1:0:%A
+ --x-grid HOUR:8:DAY:1:DAY:1:86400:%A
This places grid lines every 8 hours, major grid lines and labels
each day. The labels are placed exactly between two major grid lines
followed by the unit modifier "px" for absolute size. Any one of the options
may be absent.

+[B<-R>|B<--font-render-mode> {B<normal>,B<light>,B<mono>}]
-(this gets ignored in 1.3 for now!)
+There are 3 font render modes:
+
+B<normal>: Full Hinting and Antialiasing (default)
+
+B<light>: Slight Hinting and Antialiasing
+
+B<mono>: Full Hinting and NO Antialiasing
-This lets you customize the strength of the font smoothing,
-or disable it entirely using I<mono>. By default, I<normal>
-font smoothing is used.

bitmapped, that is, without any font smoothing. By default,
no text is rendered bitmapped.
+[B<-G>|B<--graph-render-mode> {B<normal>,B<mono>}]
+
+There are 2 render modes:
+
+B<normal>: Graphs are fully Antialiased (default)
+
+B<mono>: No Antialiasing

[B<-E>|B<--slope-mode>]
RRDtool graphs are composed of stair case curves by default. This is in line with
