`gnuplot` (Note:gnuplot ) honors the following resources for setting the
width (in pixels) of plot lines (shown here with their default values.) 0 or
1 means a minimal width line of 1 pixel width. A value of 2 or 3 may improve
the appearance of some plots. gnuplot*borderWidth: 2 gnuplot*axisWidth: 0
gnuplot*line1Width: 0 gnuplot*line2Width: 0 gnuplot*line3Width: 0
gnuplot*line4Width: 0 gnuplot*line5Width: 0 gnuplot*line6Width: 0
gnuplot*line7Width: 0 gnuplot*line8Width: 0
`gnuplot` honors the following resources for setting the dash style used for
plotting lines. 0 means a solid line. A two-digit number `jk` (`j` and `k`
are >= 1 and <= 9) means a dashed line with a repeated pattern of `j` pixels
on followed by `k` pixels off. For example, '16' is a "dotted" line with one
pixel on followed by six pixels off. More elaborate on/off patterns can be
specified with a four-digit value. For example, '4441' is four on, four off,
four on, one off. The default values shown below are for monochrome displays
or monochrome rendering on color or grayscale displays. For color displays,
the default for each is 0 (solid line) except for `axisDashes` which defaults
to a '16' dotted line.
