iRuby notebooks¶ ↑

This notebooks are powered by Ruby kernel for IPython/Jupyter. I placed them here to show some GnuplotRB’s capabilities and ways of using it together with iRuby.

Installation¶ ↑

To use GnuplotRB gem with iRuby you need to install them both.

• iRuby installation is covered in its README. It also covers installation of iPython and other dependecies.

• GnuplotRB gem installation covered in README too.

List of notebooks¶ ↑

Embedding plots into iRuby¶ ↑

Using GnuplotRB inside iRuby notebooks is covered in:

• basic usage notebook.

2D and 3D plots¶ ↑

GnuplotRB is capable to plot vast range of plots from histograms to 3D heatmaps. Gem’s repository contains examples of several plot types:

• heatmaps

• vector field (Thanks, Alexej)

• math equations

• 3D visualizations

• histogram

Possible datasources¶ ↑

GnuplotRB may take data in Ruby container or in a file. Supported containers for now are Arrays, Daru::Vector and Daru::DataFrame. When data given in file, GnuplotRB pass filename to Gnuplot without reading the file into memory.

Examples of using different datasources:

• data given in file or Ruby Array

• data given in Daru containers

• data given in Daru containers (with timeseries)

• updating plots with new data

Multiplot¶ ↑

You can not only plot several datasets in single coordinate system but place several coordinate systems on a canvas.

• Multiplot example notebook.

Animation¶ ↑

It’s possible to use several plots (Plot, Splot or Multiplot objects) to create gif animation.

• Animation example notebook.

Fitting data with formula¶ ↑

GnuplotRB also may be used to fit some data with given math formula.
