Draw a line of the specified width onto the graph. I<width> can be a
floating point number. If the color is not specified, the drawing is done
is stacked on top of the previous element which can be a B<LINE> or an
B<AREA>.
+Normally the graphing function makes sure that the entire B<LINE> or B<AREA>
+is visible in the chart. The scaling of the chart will be modified
+accordingly if necessary. Any B<LINE> or B<AREA> can be excluded from this
+process by adding the option B<skipscale>.
+
The B<dashes> modifier enables dashed line style. Without any further options
a symmetric dashed line with a segment length of 5 pixels will be drawn. The
dash pattern can be changed if the B<dashes=> parameter is followed by either
at which the stroke begins.
When you do not specify a color, you cannot specify a legend. Should

See B<LINE>, however the area between the x-axis and the line will
be filled.
Plot a tick mark (a vertical line) for each value of I<vname> that is
non-zero and not *UNKNOWN*. The I<fraction> argument specifies the length of
the tick mark as a fraction of the y-axis; the default value is 0.1 (10% of

start at the lower edge of the graphing area. If the fraction is negative they start
at the upper border of the graphing area.
