Dear All,

My question is regarding the plotted data points in a graph. Assume you draw a graph of sinx as: 

g1 = Plot[Sin[x], {x, -Pi, Pi}, 
      Frame -> True, FrameLabel -> {"x", "y"}, ImageSize -> 2.6*72
    ]

then how can I get all of the data points of this graph by using mathematica?

This is really important for me and I couldn't find the answer anywhere online!

Thank you for your help in advance!

Best,
Lily
