Large (2000 x 2000 element) HeatSeries

[begleysm]

I'm trying to build a capability to display Range Doppler maps. They tend to look something like this:

A 40x40 HeatSeries runs fine

I tried a 2000x2000 HeatSeries and it takes about 30 seconds to display (on a fairly beefy machine: Core-i9, 64GB RAM)

I assume that this is just way outside the scope of what Livecharts2 was designed to do. But, just in case, does anyone have a recommendation on how to create a 2D graph like this that has something like 2000x2000 cells?

You would probably need gpu accelerated charting software for this such as lightningchart.
But if it's just one time print on the chart, then the bottleneck would be point generating, so you would need to optimize that, maybe using multithreading.

LiveCharts is GPU accelerated, it is experimental in the current NuGet version (rc-5), but it will be the default in the next version, see the dev branch, it is much more performant than the current NuGet version.

Try the dev branch, actually this is a good benchmark to test the improvements in the library, currently the latest NuGet package uses CPU rendering, but on the dev branch GPU is the default now (I think the GPU view in WPF is broken and has memory leaks, see #1862).

But in general, the library is not designed for this case, at least not for now, there is an experimental virtualization algorithm (see rc-2 release) but that is for Line or bar series, will LiveCharts be a high-performance library? yes, there are multiple rendering improvements coming in the next version like #1915 and #1936, so GPU and data virtualization is definitely the way to build your plot, but that is currently not supported out of the box.
