This is similar to a feature I've seen in some audio analysis software to
apply a dynamic filter. Basically it works like this:
1. Create a sonogram (or "waterfall plot") of the timestream
2. Have the user select a region of the plot
3. Apply a filter to the timestream based on the selection (band-pass, notch,
I think this is a cool long term feature, but we need to implement a lot of
infrastructure first. The biggest one is to make datasources into a 2-way
object so that they can write data as well as read. Or perhaps just have a
new "datasink" object.
I think this kind of stuff is ~1 year away from being possible, but maybe I'm
pessimistic :-) Still, it's good to think of "big picture" functionality to
keep in the back of our minds as we move forward...
