most MantidPlot commands related to plotting/annotating curves does not work

[abuts]

the page
http://www.mantidproject.org/MantidPlot:_1D_Plots_in_Python#The_plot_legend

describes the way to plot/annotate curves. Most examples provided on this page do not work.

there is the script illustrating this:

t = table("TableTest")
if t==None:
    t=newTable("TableTest",10,3)

for i in xrange(1,10):
      t.setCell(1,i,i)
      t.setCell(2,i,i*i)
      t.setCell(3,i,i*i*i)    

gr = graph("MyTest");
if gr == None :
    gr =  newGraph("MyTest",2,1,2) 

l=gr.layer(1)
l.setTitle("Flux/Frequency")
l.setAxisTitle(Layer.Bottom, "Frequency [Hz]")
l.setAxisTitle(Layer.Left, "Flux [n/s/cm^2]")


l.setAntialiasing()
#l.insertCurve(table("Table1"), "Table1_1", Layer.LineSymbols)

l.addCurves(t, (1,3), Layer.Line, 1, 4) # returns True on success
#       self.graphFlux.insertCurve(self.t, "Flux/Frequency_2", Layer.Scatter)        

legend = l.newLegend(str(4))        
#txt=legend.addText(str(4))
legend.setOrigin(5,15)

-- last command -- setOrigin is not available. Neither are the most commands provided on the page above.

Either description or code should change.
