linesmarks

The linesmarks style connects adjacent points with straight line segments and then goes back to draw a mark composed of lines and polygons at each point. This style is only relevant for 2D plotting. Syntax:

     plot <data> with linesmarks marktype {<tag>|variable}
     {units {ps|xy|xx|yy|gxy|gxx|gyy}}
     {pointnumber N}
     {pointinterval M}

The plot with linesmarks command requires 3 to 5 columns of basic data. Additional input columns can be used to provide variable line color, fill color, or marktype. Handling of the marktype, scale, angle, and units options are exactly the same as for plot with marks.

Using specifier:

     2 column: x y
     3 column: x y scale
     4 column: x y xscale yscale
     5 column: x y xscale yscale angle

The spacing of marks along the line can be modified by two additional options. "pointinterval" (short form "pi") N tells gnuplot to only place a mark on every Nth point. "pointnumber" (short form "pn") N or tells gnuplot to mark only N of the data points, evenly spaced over the data set.
