Usage: mlr bar [options]
Replaces a numeric field with a number of asterisks, allowing for cheesy bar plots.
These align best with --opprint or --oxtab output format.
Options:
-f {a,b,c} Field names to convert to bars.
-c {character} Fill character: default '*'.
-x {character} Out-of-bounds character: default '#'.
-b {character} Blank character: default ' '.
-l {lo} Lower-limit value for min-width bar: default '0.000000'.
-u {hi} Upper-limit value for max-width bar: default '100.000000'.
-w {n} Bar-field width: default '40'.
