### count
In this example, YouPlot counts the number of chromosomes where the gene is located from the human gene annotation file and create a bar chart. The human gene annotation file can be downloaded from the following website.
* https://www.gencodegenes.org/human/
```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](https://user-images.githubusercontent.com/5798442/101999832-30b1ae80-3d24-11eb-96fe-e5000bed1f5c.png)
Note: `count` is not very fast because it runs in a Ruby script.
This is fine if the data is small, that is, in most cases. However, 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 -nrk2 | awk '{print $2,$1}' \
| uplot bar -d ' ' -t "The number of human gene annotations per chromosome" -c blue
```
## Usage ## Usage
`uplot --help` ### Why YouPlot?
``` Wouldn't it be a bit of pain to have to run R, Python, Julia, gnuplot or whatever REPL just to check your data?
Program: uplot (Tools for plotting on the terminal) YouPlot is a command line tool for this purpose. With YouPlot, you can continue working without leaving your terminal and shell.
Version: 0.2.7 (using UnicodePlot 0.0.4)
Source: https://github.com/kojix2/uplot
Usage: uplot <command> [options] <in.tsv> ### how to use YouPlot?
Commands: `uplot` is the shortened form of `youplot`. You can use either.
barplot bar
histogram hist
lineplot line
lineplots lines
scatter s
density d
boxplot box
colors show the list of available colors
count c baplot based on the number of occurrences | | |
(slower than `sort | uniq -c | sort -n -k1`) |-----------------------------------|------------------------------------------------|
| Reads data from standard input | `cat data.tsv \| uplot <command> [options]` |
| Reads data from files | `uplot <command> [options] data.tsv ...` |
| Outputs data from stdin to stdout | `pipeline1 \| uplot <command> -O \| pipeline2` |
Options: ### Where to output the plot?
-O, --pass [VAL] file to output standard input data to [stdout]
for inserting uplot in the middle of Unix pipes By default, the plot is output to *standard error output*.
-o, --output VAL file to output results to [stderr] The output file or stream for the plot can be specified with the `-o` option.
-d, --delimiter VAL use DELIM instead of TAB for field delimiter
-H, --headers specify that the input has header row ### Where to output the input data?
-T, --transpose transpose the axes of the input data
-t, --title VAL print string on the top of plot By default, the input data is not output anywhere.
-x, --xlabel VAL print string on the bottom of the plot The `-O` option, with no arguments, outputs the input data directly to the standard output. This is useful when passing data to a subsequent pipeline.
-y, --ylabel VAL print string on the far left of the plot
-w, --width VAL number of characters per row ### What types of plots are available?
-h, --height VAL number of rows
-b, --border VAL specify the style of the bounding box The following sub-commands are available
-m, --margin VAL number of spaces to the left of the plot
-p, --padding VAL space of the left and right of the plot | command | short | how it works |
-c, --color VAL color of the drawing |-----------|-------|----------------------------------------|
--[no-]labels hide the labels | barplot | bar | draw a horizontal barplot |
--fmt VAL xyxy : header is like x1, y1, x2, y2, x3, y3... | histogram | hist | draw a horizontal histogram |
xyy : header is like x, y1, y2, y2, y3... | 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 |
See Quick Start for `count`.
| command | short | how it works |
|-----------|-------|----------------------------------------------------------|
| count | c | draw a baplot based on the number of occurrences (slow) |
