#plot(x = nil, y = nil, legend = "Line 1", *args) ⇒ Object

Create a new graph object and populate plot (x, y, legend, [y,legend], [y,legend], … , [opts])

x           - default => [0...y_array.length]
y           - Y data array to plot
legend      - Line Legend to describe Y data
args        - Additional y , legend pairs to plot
opts        - Hash options at the end of the argument list
 :width => 400    - default => 800
 :height => 300   - default => 600
 :x => 100        - default => -1 # Place centered in current screen
 :y => 100        - default => -1 # Place centered in current screen
 :winTitle => "Graph 1" - default => "Graph"
