Function Documentation

plot_curve()

Bplot * plot_curve	(	long	nrow,
		double *	c0,
		double *	c1,
		double *	c2,
		double *	c3
	)

Generates 1-3 line plot.

Parameters

nrow	number of points.
*c0	independent variable.
*c1	curve 1.
*c2	curve 2.
*c3	curve 3.

Returns

Bplot* plot structure.

ps_close()

int ps_close

(

ofstream *

fps

)

Closes a postscript file.

Parameters

*fps	file handle.

Returns

int 0.

Closes a file and writes the postscript trailer line.

ps_define_arrowline()

int ps_define_arrowline

(

ofstream *

fps

)

Generates an arrow and line.

ps_graph()

int ps_graph	(	ofstream *	fps,
		Bplot *	plot,
		int	page_number
	)

Generates postscript graphs.

Parameters

*fps	output postscript file descriptor.
*plot	plot information.
page_number	page number (starts at 1).

Returns

int 0, <0 on error.

Any number of functions of a single independant variable (x) can be plot.

ps_open_and_init() [1/2]

ofstream * ps_open_and_init	(	Bstring	filename,
		Bplot *	plot
	)

Opens and initializes a postscript file.

Parameters

&filename	output postscript file name.
*plot	plot information.

Returns

ofstream* postscript file stream.

Opens a file and writes the postscript header line, the creator and 
creation date lines, and a document data specifier.

ps_open_and_init() [2/2]

ofstream * ps_open_and_init	(	Bstring	filename,
		Bstring	title,
		int	npages,
		int	width,
		int	height
	)

Opens and initializes a postscript file.

Parameters

&filename	output postscript file name.
&title	title.
npages	number of pages.
width	page width.
height	page height.

Returns

ofstream* postscript file descriptor.

Opens a stream and writes the postscript header line, the creator and
creation date lines, and a document data specifier.

ps_plot()

int ps_plot	(	Bstring	filename,
		Bplot *	plot
	)

Generates postscript graphs.

Parameters

&filename	output postscript file name.
*plot	plot information.

Returns

int 0, <0 on error.

Any number of functions of a single independant variable (x) can be plot.

ps_read()

Bplot * ps_read

(

Bstring &

filename

)

Reads a postscript file with a data table.

Parameters

&filename

input postscript file name.

Returns

Bplot* new plot.

ps_scale()

int ps_scale	(	ofstream *	fps,
		double	x1,
		double	y1,
		double	x2,
		double	y2,
		double	min,
		double	max,
		double	increment,
		double	tick_length,
		double	tick_angle,
		int	digits,
		int	fontsize,
		int	inverse
	)

Generates a scale for a postscript graph.

Parameters

*fps	postscript file descriptor.
x1	starting x coordinate.
y1	starting y coordinate.
x2	ending x coordinate.
y2	ending y coordinate.
min	minimum value.
max	maximum value.
increment	value increment.
tick_length	length of ticks.
tick_angle	angle of ticks relative to horizontal axis.
digits	number of decimal digits for labels.
fontsize	font size for labels.
inverse	flag for inverse values.

Returns

int 0.
