How does one shade a window area on a time history?

Hello,

For a presentation, I would like to color shade a given time interval on a time history -- basically a window of the time history that is processed in another figure. This isn't to color only the waveform (though I might just do that instead). This is to color the plot from -ylim to ylim for the given time interval.

Thanks for any help.

Regards

Doug Anderson

fill() or patch(). You would probably want to set the alpha data of the resulting patch.
