NAME PYX::Hist - Processing PYX data or file and print histogram. SYNOPSIS use PYX::Hist; my $obj = PYX::Hist->new(%parameters); $obj->parse($pyx, $out); $obj->parse_file($input_file, $out); $obj->parse_handle($input_file_handler, $out); METHODS "new(%parameters)" Constructor. * "output_handler" Output handler. Default value is \*STDOUT. "parse($pyx[, $out])" Parse PYX text or array of PYX text and print histogram of PYX input. If $out not present, use 'output_handler'. Returns undef. "parse_file($input_file[, $out])" Parse file with PYX data and print histogram of PYX input. If $out not present, use 'output_handler'. Returns undef. "parse_handler($input_file_handler[, $out])" Parse PYX handler and print histogram of PYX input. If $out not present, use 'output_handler'. Returns undef. ERRORS new(): From Class::Utils::set_params(): Unknown parameter '%s'. parse(): Bad end of element. Element: %s Stack has some elements. parse_file(): Bad end of element. Element: %s Stack has some elements. parse_handler(): Bad end of element. Element: %s Stack has some elements.
