# plschr(3plplot)

Set character size

## NAME

**plschr** - Set character size

## SYNOPSIS

**plschr**(*def*, *scale*)

## DESCRIPTION

This sets up the size of all subsequent characters drawn.  The actual height of a character is the product of the default character size and a scaling factor.

Redacted form: **plschr(def, scale)**

This function is used in examples 2, 13, 23, and 24.

## ARGUMENTS

- *def* (**PLFLT**(3plplot), input)

  The default height of a character in millimeters, should be set to zero if the default height is to remain unchanged. For rasterized drivers the dx and dy values specified in [**plspage**(3plplot)](/plspage/3plplot.md) are used to convert from mm to pixels (note the different unit systems used).  This dpi aware scaling is not implemented for all drivers yet.

- *scale* (**PLFLT**(3plplot), input)

  Scale factor to be applied to default to get actual character height.
