# plstyl(3plplot)

Set line style

## NAME

**plstyl** - Set line style

## SYNOPSIS

**plstyl**(*nms*, *mark*, *space*)

## DESCRIPTION

This sets up the line style for all lines subsequently drawn.  A line consists of segments in which the pen is alternately down and up. The lengths of these segments are passed in the vectors *mark* and *space* respectively.  The number of mark-space pairs is specified by *nms*.  In order to return the line style to the default continuous line, [**plstyl**(3plplot)](/plstyl/3plplot.md) should be called with *nms* =0 .(see also [**pllsty**(3plplot)](/pllsty/3plplot.md))

Redacted form: **plstyl(mark, space)**

This function is used in examples 1, 9, and 14.

## ARGUMENTS

- *nms* (**PLINT**(3plplot), input)

  The number of *mark* and *space* elements in a line.  Thus a simple broken line can be obtained by setting *nms*=1 .  A continuous line is specified by setting *nms*=0 .

- *mark* (**PLINT\_VECTOR**(3plplot), input)

  A vector containing the lengths of the segments during which the pen is down, measured in micrometers.

- *space* (**PLINT\_VECTOR**(3plplot), input)

  A vector containing the lengths of the segments during which the pen is up, measured in micrometers.
