The Synopsis has the following:
@histo = $s->histogram( 10 ); # 10 bins
for( @histo ) {
print $_->{pos}, "\t", $_->{cnt}, "\n";
}
and a similar construction for the cumulative distribution function. The corresponding textual description says
"this function returns a histogram of the data set as a ref to an array of hashes"
This does not seem to work; what does work is:
@histo = $s->histogram( 10 ); # 10 bins
for( @{ $histo[0] } ) {
print $_->{pos}, "\t", $_->{cnt}, "\n";
}
In other words it seems to be a ref to an array of arrays of hashes, with the first index being a dummy ($histo[1] seems to be empty).
Thanks,
Stephen
