Count processes by user ID.

ps aux | awk '{print $1}' | uplot count

Count the number of chromosomes where genes are located.

cat gencode.v35.annotation.gff3 \
| grep -v '#' | grep 'gene' | cut -f1 \
| uplot count -t "The number of human gene annotations per chromosome"  -c blue

• GENCODE - Human Release

Note: count is not very fast because it runs in a Ruby script. This is fine in most cases, as long as the data size is small. If you want to visualize huge data, it is faster to use a combination of common Unix commands as shown below.

cat gencode.v35.annotation.gff3 | grep -v '#' | grep 'gene' | cut -f1 \
| sort | uniq -c | sort -nrk1 \
| uplot bar --fmt yx -d ' ' -t "The number of human gene annotations per chromosome"  -c blue

uplot is the shortened form of youplot. You can use either.

The following sub-commands are available.

• -o
  • By default, the plot is output to standard error output.
  • If you want to output to standard output, Use hyphen -o - or no argument uplot s -o | .

• -O
  • By default, the input data is not shown anywhere.
  • If you want to pass the input data directly to the standard output, Use hyphen -O - or no argument uplot s -O |.
  • This is useful when passing data to a subsequent pipeline.

• -H
  • If input data contains a header line, you need to specify the -H option.

• -d
  • You do not need to use -d option for tab-delimited text since the default value is tab.
  • To specify a blank space, you can use uplot bar -d ' ' data.txt.

• -p --progress
  • Experimental progressive mode is currently under development.
  • ruby -e 'loop{puts rand(100)}' | uplot line --progress

• --help
  • The --help option will show more detailed options for each subcommand.
  • uplot hist --help

• YouPlot treats the first column as the X axis and the second column as the Y axis. When working with multiple series, the first column is the X axis, the second column is series Y1, the third column is series Y2, and so on.

• If you pass only one column of data for line and bar, YouPlot will automatically use a sequential number starting from 1 as the X-axis.

• --fmt

  • --fmt xyy --fmt xyxy --fmt yx options give you a few more choices. See youplot <command> --help for more details.
  • The fmt option may be renamed in the future.
  • The -x and -y options might be used to specify columns in the future.

• Use awk '{print $2, $1}' to swap columns. Use paste to concatenate series.

• With GNU datamash, you can manage to handle categorized data.
  • cat test/fixtures/iris.csv | sed '/^$/d' | datamash --header-in --output-delimiter=: -t, -g5 collapse 3,4 | cut -f2-3 -d: | sed 's/:/\n/g' | uplot s -d, -T --fmt xyxy
  • This is not so easy...

• Not yet supported.

You can specify default options in a configuration file in YAML format. For more information, enter the following command.

uplot --config

• csvtk
• GNU datamash
• awk
• xsv
