Show HN: Edit Time Series in the Browser

I started writing this web app during first lockdown as an experimental port of a internal desktop app we were using at my company. I was curious about the performance that could be achieved by a pure web app solution. It turned out to be quite capable so I decided to move forward.

Basically this is a handy tool to plot and edit time series, typically obtained from measurements or produced by simulations.

One of the main feature is the built in expression parser that can be used to combine time series and which is reasonably fast thanks to JIT webassembly compilation.

Thanks for sharing... did you get to the point where there was just too much data to handle or does it pretty much handle anything that storable in a file?
