It is possible to get the code that generates the graphics you added using the drawing tools.
For example, here's a quadratic where I've used the drawing tools to add in arrows to the x-intercepts:
Plot[x^2 - 4, {x, -3, 3}]
After the graphics type // InputForm
to see the code that makes the graphics. In this case I've also used /. Line[x_] -> Line
to suppress all of the points that make up the plot:
The highlighted code is that which was added by the drawing tools. It can be simplified (e.g., remove the EdgeForm
commands and replacing the Inset
Cell
with just a plain Text
command) when you add it back to your original Plot
, which can be done with an Epilog
(or a Prolog
) or by using Show
.
