## auto legend for plot...

Is there any way to automatically create a legend for a plot of a list of functions? The problem is, I'd rather not specify the legend and maple require the exact number so I cannot specify a generic length such as [1,2,3,4,5,6,7,8].

plot([f1(x), f2(x), f3(x), sin(x)*cos(x)*sin(3x^2 + cos(x))], x=1..34)

The point is that I do not want or care what the legend is(except the names shouldn't be long). I just want to be able to use it to select the plots easily and to be able to reference them(so the naming matters in that the order shoudl be obvious).

Maple

When I try to get a higher resolution plot using numpoints, the lines are jagged and look lower resolution.

You can see the difference, the first does not look anti-aliased whil ethe second does(although the 2nd looks far better on my comp)

## Unable to evalulate plot of Fourier tran...

Maple
```with(inttrans):
sinc := x->piecewise(x = 0, 1, sin(Pi*x)/x/Pi):
S := x->sinc(x):
SE := x->sinc(x)*exp(-x^2):
plot(abs(fourier(SE(x),x,s)),s=0..5)

```

works fine for S but when trying to plot SE I get

Warning, unable to evaluate the function to numeric values in the region; see the plotting command's help page to ensure the calling sequence is correct

I simply want to plot the fourier transform of a function so I can see it's frequency response. Maple seems to be breaking for more complex functions. It seems to be doing this when it can't evaluate the function exactly, which I don't care for plots.
