5.23.21 linewidth

set linewidth <value>

Sets the default linewidth, in units of pt, of the lines used to plot datasets onto graphs with the ‘lines’ plot style (see the plot command for details of plot styles), for example in the following statement:

plot sin(x) with lines

The linewidths of individual datasets can be set as follows; the set linewidth setting only affects plot statements where no linewidth is manually specified:

plot sin(x) with lines linewidth 5.0
