Use of index property is required for me to be able to draw a curve based on a simple dataset of values (x, y) : dataset = Gnuplot::DataSet.new( [x, y] ) do |ds| ds.with = "linespoints" ds.notitle ds.using = "1:2" ds.index = 0 end
Make SPlot.to_gplot use parent's implementation
Conflicts: lib/gnuplot.rb Merge with branch master from rdp/ruby_gnuplot
Readme fixes and linecolor property
Allow unsetting Gnuplot variables
Minor correction to README
This change adds a method Gnuplot::Plot.unset(var) to unset the Gnuplot variable var. As the order of sets and unsets are important for Gnuplot, a new array "settings" was introduced in which the set and unset tasks are accumulated.
