Thanks to @tangui Plotex v0.3.0 is out that uses SVG Markers for line points. It speed up rendering almost 2x for ~80,000 points!

If anyone is keen to take an early look, I can make time over the next 24hrs to break it out into a new, public github repo.
I’d love to take a look at it.

Sorry to revive an old thread, but I think this may be useful for others. I was looking at doing charts in LiveView this past week. I really wanted charts to be rendered with JS rather than SVG, due to the interactive element.
I found the Chartkick library, but it didn’t work with LiveView (at least for me) due to how it expects script tags to run. I was able to pretty quickly modify chartkick.ex to work with LiveView though.
I was unsure how to get rid of the raw requirement with Chartkick.ex, but tbh I didn’t spend more than a few minutes thinking about that.
These charts will update if the data source updates, but does so by destroying and re-allocating the chart. That probably isn’t the most efficient thing, but my use case is static 30-day charts.

Hey, did you ever finish porting/releasing this? As a fan of D3.js it would be a very helpful lib to have in Elixir! And it would save me from having to do some annoying mathematical calculations (this is the real reason I’m asking 
)

Indeed - Contex has scale & axis - this page shows a few examples: ContEx Charts.
One thing that’s missing is the ability to override the calculated domain - the “nice” algorithm gets applied by default.
