How To Merge PDF Online?

Is there any tool or method to merge my graph to an already plotted PDF graph? I want to compare my graph with the previously plotted graph.
Graphing — particularly modern graphing on an x-y coordinate plane — was created by Rene Descartes. There is a little story about how he thought this up. Rene was an insomniac. He couldn’t sleep at night. Not that anyone could blame him. The beds in that day were sacks filled with straw and hay — and the vermin that infested them. Lie down and the little beasties knew dinner was waiting! But Rene also was afraid of the dark. So he kept a candle lit at night. That might also have prevented him from sleeping. His room was a modest rectangular room. And as he lay awake, a fly lit on the ceiling. Now instead of thinking (like ordinary people), “How can I swat that fly?”, he thought, “How can I find out exactly where that fly is on the ceiling?” So he reasoned that he could measure a length perpendicular to one wall and a length perpendicular to the other wall, meeting at the fly. The pair of measurements would tell him where the fly was! And so was born the Cartesian Coordinate System and modern graphing. The story may be a tad apocryphal, but I’m pretty sure that something like that sparked his imagination. Very often things in the real world help us understand mathematics, even giving us the ability to create math on our own.

So here are some of the things that helped us understand the coordinate system of modern graphing. First, of course, were the tools of science. The microscope was invented by Robert Hooke. His son, the great Sir Isaac, used the new instrument, too. The microscope allows us to see cells and blood vessels. It also helps solve problems related to blood cells. But it doesn’t allow us to see or draw the cells in such detail that we could make such an accurate sketch of the cell shape. But that was exactly what Hooke had in mind. To make a precise drawing of a cell, and then to draw tiny circles representing the individual parts inside the cell. He imagined how he could put tiny pencil marks around the cells to represent the position of individual parts. When he went to see his friend, John Napier, he showed him this.
