Subject: Re: 2D array to array of hashes with repeating header

data = [[:time, :pressure],[0,2.3],[1,4.1],[2,7.56],...]
axes = data.shift   #shift the axes labels out from the data set
new_data = data.collect{|point| {axes[0] => point[0], axes[1] => point
[1]}}  #pair the axes with the data by iterating and collecting the
results
