YouPlot is a command line tool that draws plots on the terminal. :bar_chart: Powered by [UnicodePlot](https://github.com/red-data-tools/unicode_plot.rb)

## Installation ``` brew install youplot ``` ``` gem install youplot ``` ``` nix shell nixpkgs#youplot ``` ``` guix install youplot ``` ``` conda install -c conda-forge ruby conda install -c conda-forge compilers gem install youplot ``` ## Quick Start barplot

`uplot [options] ` ### barplot ```sh curl -sL https://git.io/ISLANDScsv \ | sort -nk2 -t, \ | tail -n15 \ | uplot bar -d, -t "Areas of the World's Major Landmasses" ```

barplot

```sh # For offline user: Sorts files in a directory by size and shows a bar graph. ls -l | awk '{print $9, $5}' | sort -nk 2 | uplot bar -d ' ' ``` ### histogram ```sh echo -e "from numpy import random;" \ "n = random.randn(10000);" \ "print('\\\n'.join(str(i) for i in n))" \ | python3 \ | uplot hist --nbins 20 ```

histogram

### lineplot ```sh curl -sL https://git.io/AirPassengers \ | cut -f2,3 -d, \ | uplot line -d, -w 50 -h 15 -t AirPassengers --xlim 1950,1960 --ylim 0,600 ```

lineplot

```sh # For offline users: Calculates sin values (0-2*pi) and plots a sine wave. python3 -c ' from math import sin, pi data = "\n".join(f"{i*pi/50}\t{sin(i*pi/50)}" for i in range(101)) print(data)' | uplot line ``` ### scatter ```sh curl -sL https://git.io/IRIStsv \ | cut -f1-4 \ | uplot scatter -H -t IRIS ```

scatter

```sh # For offline users cat test/fixtures/iris.csv | cut -f1-4 -d, | uplot scatter -H -d, -t IRIS ``` ### density ```sh curl -sL https://git.io/IRIStsv \ | cut -f1-4 \ | uplot density -H -t IRIS ```

density

```sh # For offline users cat test/fixtures/iris.csv | cut -f1-4 -d, | uplot density -H -d, -t IRIS ``` ### boxplot ```sh curl -sL https://git.io/IRIStsv \ | cut -f1-4 \ | uplot boxplot -H -t IRIS ```

boxplot

```sh # For offline users cat test/fixtures/iris.csv | cut -f1-4 -d, | uplot boxplot -H -d, -t IRIS ``` ### count Count processes by user ID. ```sh ps aux | awk '{print $1}' | uplot count ``` Count the number of chromosomes where genes are located. ```sh cat gencode.v35.annotation.gff3 \ | grep -v '#' | grep 'gene' | cut -f1 \ | uplot count -t "The number of human gene annotations per chromosome" -c blue ```

count

* [GENCODE - Human Release](https://www.gencodegenes.org/human/) 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. ```sh 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 ``` ## Usage ### Commands `uplot` is the shortened form of `youplot`. You can use either. | Command | Description | |------------------------------------------------|-----------------------------------| | `cat data.tsv \| uplot [options]` | Take input from stdin | | `uplot [options] data.tsv ...` | Take input from files | | `pipeline1 \| uplot -O \| pipeline2` | Outputs data from stdin to stdout | ### Subcommands The following sub-commands are available. | command | short | how it works | |-----------|-------|----------------------------------------| | barplot | bar | draw a horizontal barplot | | histogram | hist | draw a horizontal histogram | | lineplot | line | draw a line chart | | lineplots | lines | draw a line chart with multiple series | | scatter | s | draw a scatter plot | | density | d | draw a density plot | | boxplot | box | draw a horizontal boxplot | | | | | | count | c | draw a barplot based on the number of occurrences (slow) | | | | | | colors | color | show the list of available colors | ### Output the plot * `-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 | `. ### Output the input data * `-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. ### Header * `-H` * If input data contains a header line, you need to specify the `-H` option. ### Delimiter * `-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`. ### Real-time data * `-p` `--progress` * Experimental progressive mode is currently under development. * `ruby -e 'loop{puts rand(100)}' | uplot line --progress` ### Show detailed options for subcommands * `--help` * The `--help` option will show more detailed options for each subcommand. * `uplot hist --help` ### Set columns as x-axis or y-axis * 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 --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, $1}'` to swap columns. Use `paste` to concatenate series. ### Categorical data * With GNU datamash, you can manage to handle categorized data. * `cat test/fixtures/iris.csv | sed '/^$/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... ### Time series * Not yet supported. ### YouPlot Configuration (youplotrc) You can specify default options in a configuration file in YAML format. For more information, enter the following command. ``` uplot --config ``` ## Tools that are useful to use with YouPlot * [csvtk](https://github.com/shenwei356/csvtk) * [GNU datamash](https://www.gnu.org/software/datamash/) * [awk](https://www.gnu.org/software/gawk/) * [xsv](https://github.com/BurntSushi/xsv) ## Contributing YouPlot is a library under development, so even small improvements like typofix are welcome!
