since Mathematica decides the discretization in making a plot, I want
it to show me the data it finally uses in plotting the function.

Hence I define a plot by the following function
plot1R1 =loglogPlotter[0.9 ,N[ 45 Degree],0,0,0.8 ,ref,B1];

Then I use InputForm[] as follows:

InputForm[{plot1R1}]

which returns the following data
Graphics[{AbsoluteThickness[1], {Line[{{-6.999999583333333, -1.296010912273682},

Now I want to extract the data from the above function
scientifically, ie,not using ''check balance'' for example.

Is there some way of doing it? There are, of course, string manipulation
methods, but I want to avoid them
