Simple histogram creation

see bin/histogram-demo.pl

bin/data-histogram.pl:

  usage: data-histogram.pl - create a histogram from a series of integers

  --bucket-count    number of buckets - defaults to 20
  --line-length     max length of histogram lines - defaults to  100
  --hist-char       character used for histogram lines - defaults to *
  --lower-limit-op  operator for lower bounds - one of < > <= >=
  --lower-limit-val value for lower bound
  --upper-limit-op  operator for upper bounds - one of < > <= >=
  --upper-limit-val value for upper bound
  --file            read data from a file
                    this is useful only for files to large for memory
                    this option is quite slow as it uses the Tie::File package
                    the only advantage is very large files may be processed

  --h|help

  example:

Histogram of reads

head -1 /home/jkstill/perl/modules/roc/data/asm-dg-metrics-1.csv  | cut -f7 -d,
READS

(looks like a limit bug in the demo)

filter on READS of between 1 and 10

grep shrprd01 /home/jkstill/perl/modules/roc/data/asm-dg-metrics-1.csv  | cut -f7 -d, | data-histogram.pl --lower-limit-op '>=' --lower-limit-val 1 --upper-limit-op '<=' --upper-limit-val 10
Bucket Count Decreased to 18 to avoid modulus divide by zero

Histogram for size of reads <  ~80 Megabytes

head -1 /home/jkstill/perl/modules/roc/data/asm-dg-metrics-1.csv  | cut -f11 -d,
