Description

Here's a screenshot of a scalar plotted in time series with a large smoothing factor. Notice how the smoothed yellow trajectory isn't visible.

Here's the same plot in the scalar tab with the same smoothing factor. Both smoothed trajectories are visible.

Seems like a straightforward fix using the painter's algorithm: first draw all the unsmoothed trajectories, and then draw all the smoothed trajectories.

Research direction

Start by reproducing the scalar plot in the TimeSeries tab with a large smoothing factor, then compare its rendering with the scalar tab shown in the issue. The issue is done when the smoothed trajectory is visible on top of the unsmoothed trajectories in the TimeSeries view.
