## 1.52.31 linewidth

    set linewidth <value>

The `set linewidth` command sets the default line width of the lines used to plot datasets onto graphs using plot styles such as `lines`, `errorbars`, etc. The value supplied should be a multiplicative factor relative to the default line width; a value of 1.0 would result in lines being drawn with their default thickness. For example, in the following statement, lines of three times the default thickness are drawn:

    set linewidth 3
    plot sin(x) with lines

The `set linewidth` command only affects plot statements where no line width is manually specified.
