[Cube] Needed: OS X Digital "Graph Paper" Program

[George Pepper]

Greetings fellow listers,

I have a wonky music theory blog, and I have the ability to add musical examples to it with standard musical notation, but I am putting together a post about the technical mechanics of melody that will require me to post examples in graphic form.  What I am looking for is basically a digital representation of the standard 12 lines per inch graph paper that we are all familiar with, but in a program that will run in OS X and it must allow me to "draw" lines on the graph (Several colors if possible), label the graph with descriptions etc. and save them.  The saved format is not to important - it can be a format speciffic to that program - because of course I can change them to PDF and then to JPG, which is what I do with my musical examples, then I just add them to my Smugmug account and link to them.

I have not been able to locate such a program, but I'm assuming that this must be something that is quite common and simple to do, graphs being needed for so many applications.  A nice little freeware app would be perfect if there is one.

Thanks, and you can check out the blog if you want here:
