Hello everyone,
Say I have two plots, y=x^2 and y=2x,
aligned vertically using GraphicsColumn.
Their domains are aligned because x runs
from -3 to +3 in both. I'd like to be
able to draw a line from a point in the
top graph to a point in the bottom graph. How can I do that?
Regards,
Gregory
Hi, Gregory,
Here is a minimalistic approach. Try it:
pl1 = Plot[x^2, {x, -3, 3}];
pl2 = Plot[2 x, {x, -3, 3}];
Show[{GraphicsColumn[{pl1, pl2}],
Graphics[{Red, Thick,
Line[{Scaled[{0.6, 0.12}], Scaled[{0.6, 0.64}]}]}]}]
Have fun, Alexei
