There is a logical error in your description. This array would not have 
the shape (150,150), but (2,150).

An image with 150x150 pixels has in total 150x150=22500 pixels. You've 
got only 300 datapoints. So it's very unclear what you want to do. A 
"contour plot" displays lines of equal height over a two-dimensional 
dataset, as in a topographic map. You don't seem to have a 
two-dimensional dataset at first place; maybe you already have *contour 
data*, and you just want to plot(x,y) ?
