NAME

SYNOPSIS

DESCRIPTION

Character height is in C-PLOT millimeters and refers to upper-case letters.  Width is controlled by setting the height-to-width ratio, with a default of 2.  For best results, reduce the ratio for small characters, thus making them wider, and increase it for large ones.

Character slant is given in degrees.  Positive values slant characters to the right, negative values to the left.

With no arguments, you are prompted to set the height, height-to-width ratio and slant for each text group in turn.  Current values are given in parenthesis; only the parameters for which you enter values will be changed. Entering one value changes only the height for the characters affected.  Entering two values changes the height and height-to-width ratio.  Entering three values changes the height, height-to-width ratio and slant.

Parameters for a single text element can be set by entering cs and the appropriate one-letter code. You can follow the letter with a value for the height and, optionally, for the height-to-width ratio and slant. Otherwise you will be prompted for values for just that text element.

The argument t selects the title, l the axis labels, n the axis numbers, s the plotting symbol, k the key and annotation and d the date.

Changing the width of the symbol controls the width of error bars and the size of data masking in gd mode 4.  The symbol height controls the minimum error bar size that is displayed.  To display error bars that have small magnitudes, decrease the symbol height.

Absolute character dimensions, given in millimeters, are strictly accurate only on the HP-GL plotter.  The actual dimensions of characters drawn using a graphics filter will depend on the mapping of HP-GL units to the graphics device.
