This is a graphics problem.
When you execute the following,
ParametricPlot[{t, Sin@t}, {t, 0, 6 Pi},
AspectRatio->Automatic,
Background->GrayLevel[.8], Frame->True
]
You'll see that mma leaves a very wide blank space on left and right
sides of the graphic, something very undesirable. After some study, I
find that this will occur whenever the AspectRatio of the plot is very
small, doesn't matter whether it's set by Automatic or explicitly. To see
this, plot any curve and set a small AspectRatio, for example
ParametricPlot[{Cos@t, Sin@t}, {t, 0, 2 Pi},
AspectRatio->1/10,
Background->GrayLevel[.8], Frame->True
]
Why is this? To be sure this is not my ignorance of mma, compare the
exact same plot without the blank sides, produced by the following method.
1) Plot any graph and set AspectRatio to 1.
ParametricPlot[{Cos@t, Sin@t}, {t, 0, 2 Pi},
AspectRatio->1,
Background->GrayLevel[.8], Frame->True
]
2) If you are using a Mac front end (or other similiar notebook
frontend), uncheck the "Preserve AspectRatio" in the "Graph" menu.
3) Click and drag to widen your graphic to get the desired small AspectRatio.
As you can see, the same plot generated by this method do not have the
wide blank space. The blank space is clearly something of a bug nature.
Anyone knows why?

Please answer by email. I don't have a good newsreader.

they translate it into mma language, and at once it is something
