I can’t figure out how to draw the waveform for a Fourier transform frequency domain. As a test case I picked the reals `{0.0, 0.5, 1.0, 2.5, 4.0, 2.0}`

and ran them through `Fourier.Forward(Complex[])`

with all imaginaries being zero, getting:

```
Magnitude, Phase
4.082, 0.000
2.208, 2.337
0.736, -2.337
0.000, 0.622
0.736, 2.337
2.208, -2.337
```

and

```
Real, Imaginary
4.082, 0.000
-1.531, 1.591
-0.510, -0.530
0.000, 0.000
-0.510, 0.530
-1.531, -1.591
```

Assuming the original samples are placed at unit intervals, how do I figure out the y-value of the waveform at any real parameter? I.e. the blue curve:

Edit:

I’ve gotten close-ish by harvesting the magnitudes and phases of complex frequency vector (but only elements 1 to N/2, so I *think* I’m skipping all negative frequencies). But the final graph doesn’t intersect the sample points. It’s close, and I can see it bulging in the correct location when I adjust the samples, but even allowing for a corrective vertical scale+move I cannot get the graph to exactly intersect the points:
