When you are done fetching and processing the data, it is time to
graph it (or print it). This ends the B<rrdtool graph> sequence.
-=head1 OPTIONS
-
+Use B<graphv> instead of B<graph> to get detailed information about the
+graph geometry and data once it is drawn. See the bottom of the document for
+more information.
-=head2 B<graphv>
+=head1 OPTIONS
-This alternate version of B<graph> takes the same arguments and performs the
-same function. The I<v> stands for I<verbose>, which describes the output
-returned. B<graphv> will return a lot of information about the graph using
-the same format as rrdtool info (key = value). See the bottom of the document for more information.
=head2 I<filename>
A horizontal string at the top of the graph and/or a vertically
placed string at the left hand side of the graph.
-=head2 Right Axis
-
-[B<--right-axis> I<scale>B<:>I<shift>]
-[B<--right-axis-label> I<label>]
-
-A second axis will be drawn to the right of the graph. It is tied to the
-left axis via the scale and shift parameters. You can also define a label
-for the right axis.
-
-[B<--right-axis-format> I<format-string>]
-
-By default the format of the axis lables gets determined automatically. If
-you want todo this your self, use this option with the same %lf arguments
-you know from the PRING and GPRINT commands.
=head2 Size
Gridfitting is turned off for PDF, EPS, SVG output by default.

each day. The labels are placed exactly between two major grid lines
as they specify the complete day and not just midnight.

the appropriate units (k, M, etc.) instead of using exponential notation.
Note that for linear graphs, SI notation is used by default.

=head2 Legend
[B<-z>|B<--lazy>]
Only generate the graph if the current graph is out of date or not existent.
-Note, that only the image size will be returned, if you run with lazy even
-when using graphv and even when using PRINT.
-
+Note, that all the calculations will happen regardless so that the output of
+PRINT and graphv will be complete regardless. Note that the behaviour of
+lazy in this regard has seen several changes over time. The only thing you
+can realy rely on before rrdtool 1.3.7 is that lazy will not generate the
+graph when it is already there and up to date, and also that it will output
+the size of the graph.
[B<--daemon> I<address>]
A green arrow is made by: C<--color ARROW#00FF00>
+[B<--border> I<width>]]
+
+Width in pixels for the 3d border drawn around the image. Default 2, 0
+disables the border. See C<SHADEA> and C<SHADEB> above for setting the border
+color.
+
[B<--zoom> I<factor>]
Zoom the graphics by the given amount. The factor must be E<gt> 0
Use Times for the title: C<--font TITLE:13:Times>
+Note that you need to quote the argument to B<--font> if the font-name
+contains whitespace:
+--font "TITLE:13:Some Font"
+
If you do not give a font string you can modify just the size of the default font:
C<--font TITLE:13:>.
