Function Documentation

void plot_histogram	(	gsl_vector *	data,
		FILE *	f,
		size_t	bin_count,
		char *	with
	)

This convenience function will take in a gsl_vector of data and put out a histogram, ready to pipe to Gnuplot.

Parameters

data	A gsl_vector holding the data. Do not pre-sort or bin; this function does that for you via apop_data_to_bins.
bin_count	The number of bins in the output histogram (if you send zero, I set this to , where is the length of the vector.)
with	The method for Gnuplot's plotting routine. Default is "boxes", so the gnuplot call will read plot '-' with boxes. The "lines" option is also popular, and you can add extra terms if desired, like "boxes linetype 3".
