# Linespoints

The linespoints style (short form lp) connects adjacent points with straight line segments and then goes back to draw a small symbol at each point. Points are drawn with the default size determined by set pointsize unless a specific point size is given in the plot command or a variable point size is provided in an additional column of input data. Additional input columns may also be used to provide information such as variable line color. See lines (p. ) and points (p. ).

The pointinterval (short form pi) property of the linetype can be used to control whether or not every point in the plot is given a symbol. For example, 'with lp pi 3' will draw line segments through every data point, but will only place a symbol on every 3rd point. A negative value for pointinterval will erase the portion of line segment that passes underneath the symbol. The size of the erased portion is controlled by set pointintervalbox.
