Smoothed and simplified plots #208

Closed abyrd closed 7 years ago

abyrd commented 7 years ago

There is something to be said for the simplicity of the non-spectrogram plots in the older Analyst interface. They don't look pixelated. We could extract 25th / 50th / 75th percentile and make a smooth plot like in the old Analyst.

On the spectrogram, we could just use the browser's built in interpolation to scale up the spectrogram image smoothly.

We should definitely have a KDE mode on the histogram. Maybe a slider that adjusts the kernel width, and with the slider at zero it's a normal binned histogram.

We could also render the spectrogram as a 2D kernel density plot. I bet this would look amazing.

I don't think the built-in scaling in the browser will do what we want. But I'd be in favor of switching to using KDE. Rendering this stuff is blindingly fast so I think it would perform just fine. But we should move this issue to conveyal/analysis-ui.
