ggplotd-cli 0.2.0

ggplotd-cli

Command line tool for quickly plotting graphs using ggplotd. It's designed to complement the tsv-utils toolset.

Features:

• Draw scatter, line, box, histogram (1D and 2D), kernel density (1D and 2D) and word-cloud-style label plots.
• Output to GUI window or to a variety of image file formats (as supported by Cairo backend).

Currently it's an 80% solution: it's useful for a lot of quick data visualisation, but has many limitations. Please support the underlying ggplotd library if you need more features.

Quick Start

By default, ggplotd-cli reads in tab-separated values and draws a scatter graph, using the first column for x values, the second column for y values and (optionally) the third column for tagging different data series.

$ # Generate some sin() and cos() data
$ cat sincos.tsv.dj
[: import std.math;
foreach (x; iota(-4.0, 4.0, 0.1)) :]
[= x, "\t", sin(x), "\tsin" ]
[= x, "\t", cos(x), "\tcos" ]
$ djinn sincos.tsv.dj
$ head sincos.tsv
-4	0.756802	sin
-4	-0.653644	cos
-3.9	0.687766	sin
-3.9	-0.725932	cos
-3.8	0.611858	sin
-3.8	-0.790968	cos
-3.7	0.529836	sin
-3.7	-0.8481	cos
-3.6	0.44252	sin
-3.6	-0.896758	cos
$ # Plot to GTK window
$ ggplotd < sincos.tsv 
$ # Plot to PNG image file
$ ggplotd -o sincos.png < sincos.tsv
