Maybe there is another approach that looks more at the "value" of each
point for showing extrema and other significant changes in direction of
the line?

You could assign each point a priority. The priority for recently added
points would have to be tentative, and adjusted based on subsequent
data. The priority would depend on things like changes in direction, how
far the point is above or below the running mean...

The first point, the most recently added point, and extrema over a long
period are high value. On the other hand, a point that close to the
straight line between its neighbors is low value.

You could implement this with a 500 element priority queue and a
circular buffer for the recently added points that need their priorities
recalculated as new points are added.
