# xan hist
```txt
Print a horizontal histogram for the given CSV file with each line
representing a bar in the resulting graph.
This command is very useful when used in conjunction with the `frequency` or `bins`
command.
Usage:
xan hist [options] []
xan hist --help
hist options:
--name Name of the represented field when no field column is
present. [default: unknown].
-f, --field Name of the field column. I.e. the one containing
the represented value (remember this command can
print several histograms). [default: field].
-l, --label Name of the label column. I.e. the one containing the
label for a single bar of the histogram. [default: value].
-v, --value Name of the count column. I.e. the one containing the value
for each bar. [default: count].
-B, --bar-size Size of the bar characters between "small", "medium"
and "large". [default: medium].
--cols Width of the graph in terminal columns, i.e. characters.
Defaults to using all your terminal's width or 80 if
terminal's size cannot be found (i.e. when piping to file).
Can also be given as a ratio of the terminal's width e.g. "0.5".
-R, --rainbow Alternating colors for the bars.
-m, --domain-max If "max" max bar length will be scaled to the
max bar value. If "sum", max bar length will be scaled to
the sum of bar values (i.e. sum of bar lengths will be 100%).
Can also be an absolute numerical value, to clamp the bars
or make sure different histograms are represented using the
same scale.
[default: max]
-c, --category
Name of the categorical column that will be used to
assign distinct colors per category.
Incompatible with -R, --rainbow.
--color When to color the output using ANSI escape codes.
Use `auto` for automatic detection, `never` to
disable colors completely and `always` to force
colors, even when the output could not handle them.
[default: auto]
-P, --hide-percent Don't show percentages.
-u, --unit Value unit.
-D, --dates Set to indicate your values are dates (supporting year, year-month or
year-month-day). This will sort the bars by date, and add missing dates.
-G, --compress-gaps If given, will compress gaps of minimum consecutive
entries set to 0 and replace it with an ellipsis.
--scale Apply a scale to the values. Can be one of "lin", "log",
"log2", "log10" or "log(custom_base)" like "log(2.5)".
[default: lin]
Common options:
-h, --help Display this message
-n, --no-headers When set, the file will be considered as having no
headers.
-d, --delimiter The field delimiter for reading CSV data.
Must be a single character.
