Documentation & cosmetic fixes

Gem documentation updated with YARD format.
Other documentation updates are listed in #33.
Release also includes partial fix for #34.

Animation and fit

New

• Animation - now one can create animated gifs with plots as frames. So it's possible to add one more axes (time) to a plot. Usage is shown in animated plots notebook.
• Fit - with GnuplotRB::fit one can find best fit curve for dataset and plot it. Usage is shown in fit example notebook.
• Added support for Daru::DateTimeIndex. See #24 .

Multiplot, iRuby and Daru support

New features

To make embedding GnuplotRB plots into iRuby notebooks easier this release contains improvements into iRuby support. Plots may be embedded as images or plain text and there is a notebook where you can see how to do it.

Since this release GnuplotRB is capable to output several plots to single multiplot layout. There is a notebook that covers this feature usage.

GnuplotRB can now use data from Daru structures (Vector and DataFrame) to create visualizations. Small example is here.

Notebook examples

Apart from this there are more notebooks which contain some examples of plots you can reach with GnuplotRB:

• Plotting heatmaps
• Plotting vector field
• Plotting math equations
• Plotting data given as points
• Plotting 3D visualizations
• Histogram example
• Updating existing plots

2D and 3D plotting

The gem already may be used to visualize datasets given as mathematical equations or points arrays. Notebook examples to start with gnuplot gem:

• Plotting math equations
• Plotting data given as points
• Plotting 3D visualizations
• Histogramm example
• Updating existing plots
