A Graph Mode

I think they're should be a graph mode. Like you click on "Graph Mode" while viewing something, and type in a code like:
Graph(x, y, xstep, ystep)
And if you typed in
Graph(Object38.Velocity, Sun3.Velocity, 100km, 2000km)
And it turns it into a graph like:

8000km|
6000km|
4000km|
2000km|__________________
--------.0|100km| 200km| 300km
Where x is Object38's velocity, and y is Sun3's velocity. And also it would be useful if you added a "Calculate Formulae"
e.g.
A diagonal line equally between x any y would be x=y and y=x
Where a diagonal line equally between y=x and y would be y = 2x. And if the line didn't cross through the centre it could be y = 2x + 3. Also you should be able to enter a formulae and it too calculate a graph.
