[Rock-dev] new realtime plot widget

[Alexander Duda]

I added a plot widget to rock_widget_collection (branch vtk) which is
based on vtk.

You are welcome to try it out.

script which was used to generated the attached png:
require 'vizkit'

widget = Vizkit.default_loader.Plot2d
widget.setXRange(0,300)
widget.setColor(0,255,255,0)
widget.setColor(1,255,255,255)
widget.setColor(2,0,0,255)
widget.setPlotLabel(0,"Test")
widget.setPlotLabel(1,"Test2")
widget.setPlotLabel(2,"Test3")
widget.setTitle("Plot Widget")

timer  = Qt::Timer.new
i = 0
timer.connect(SIGNAL('timeout()')) do
    widget.addPoint(0,i,5.0* Math::sin(i.to_f*Math::PI/20))
    widget.addPoint(1,i,1+2.0* Math::sin(i.to_f*Math::PI/10))
    widget.addPoint(2,i,3+10.0* Math::sin(i.to_f*Math::PI/100))
    i=i+1
    widget.update
end

timer.start(100)

widget.show
Vizkit.exec
