plot 2D/3D points with labels

[octavian-ganea]

Is it possible to plot 2d/3d points with labels? That would be useful for visualizing word embeddings for example. Thanks.

You can use the gnuplot.raw() function to enable it.

As an example, for anyone wondering in the future:

g = require 'gnuplot'
g.pngfigure('plots.png')
g.title('Plots of data')
g.raw("plot 'data.txt' using 2:3:(sprintf('(%d)', $1)) with labels point pt 7 offset char 1,1 notitle")
g.raw("set term png size 1280, 960") -- sets size of plot
g.xlabel('x')
g.ylabel('y')
g.plotflush()

where data.txt might look like this:

1     0.34    0.5
2     0.26    0.6
3     0.11    0.7
...

However, are there ever plans to add labeling support natively? Labels seem important and someone not versed in gnuplot may struggle with finding the right raw command.

@suryabhupa the answer is no, unless someone sends a PR.

While the labeling might be more of a specific case, I can add an example in the docs?

sounds good
