Hi Aditya,

if you pass a 1-dimensional interatable to the plot-function the elements are 
plotted over their indices. In your case [1, 2] gives the y-values and the 
indices [0, 1] are used as x-values.

I don't know if there is some kind of vector class yet, but meanwhile you 
could set up your one like in the attached small example.

Kind regards,
Matthias
