Plot: How to query currently hidden items

[metasim]

I'm trying to determine if a plot item is visible or not so that the state of another control can be affected by it. I see this method on LegendWidget...

egui/crates/egui_plot/src/legend.rs

Lines 219 to 226 in 44d65f4

	// Get the names of the hidden items.
	pub fn hidden_items(&self) -> ahash::HashSet<String> {
	self.entries
	.iter()
	.filter(|(_, entry)| !entry.checked)
	.map(|(name, _)| name.clone())
	.collect()
	}

...but I can't figure out how to get access to the LegendWidget from the Response (or other pathway). Is this currently possible?

Note, I've only been using egui for a few weeks, so apologies if this is a beginner question.

I think the way to do that currently is to call PlotMemory::load, using the same id you used for the plot itself.
