Hi, you can combine graphics with Show: Show[{ Plot[Sqrt[x], {x, 0, 100}], Graphics[{Line[{{0, 0}, {100, 10}}]}] }] Another way is to have a look at the Epilog option of Plot.

Could not bring to work graphics primitive Line since I could make it plot only on a separate graph. How can one Plot and Line on the same figure? > > Mark. >
