Isobar charts

[Alex1933]

While looking for ways to display simulated acoustic measurements, I came across Chart.JS and I am extremely excited and impressed by the possibilities it offers.
I have certainly programmed various things before, but web applications are rather new territory for me.
In particular, I am looking for a way to display isobar diagrams after a calculation in a web application. Since I don't like pixel graphics and a corresponding rendering seems to be quite slow, I went searching on the web.
Unfortunately, I can't find anything and am therefore somehow dependent on help from others.
Isobars are mostly only needed by weathermen and few understand them. Honestly, I have mostly only seen such diagrams in connection with acoustic measurements.
Perhaps the whole thing is not so difficult when I look at the possibilities of Chart.JS.
Can anyone help me? Maybe something like this already exists and I just haven't found it.

I don't know that there is a way to do this natively. Are you able to post a pic of what you're trying to create? I could only find isobar charts for weather applications.

No Problem.
This is the result from an acoustic measurement program. In the diagram, the sound pressure level is color coded,
The X-axis represents the frequency reference and the Y-axis the angle at which the test object was viewed.
There are various measurement errors to be seen, but these are not the point here.

Hmm, so on this front I'm not sure if Chart.js can do this. My best thought on how to achieve this would be to manually create some kind of gradient but I don't know how to do that without resorting to WebGL.
