Research direction

Start by reviewing the WPF DataLogger and Plot.Add APIs, along with the PlottableList behavior shown in the issue. Determine whether an existing logger can be attached to a second plot while preserving its live data, and define the expected behavior for the original plot and the shared data source.

Description

Hello,

I'm working on a WPF application using ScottPlot 5.0.55 , and I have a situation where I want to reuse a DataLogger that was already created and added to a plot.

For example:

// First plot
var logger = WpfPlot1.Plot.Add.DataLogger();
for (int x = 0; x < 10; x++)
{
    logger.Add(x, Generate.RandomWalker.Next());
}
WpfPlot1.Refresh();

Later, I would like to move or reuse this same logger on another plot, like this:

// Reuse the same logger in a different plot
WpfPlot2.Plot.Add(logger);
WpfPlot2.Refresh();

I also tried adding the logger manually to the PlottableList, but this doesn't seem to work properly:

// is someThing wrong
WpfPlot2.Plot.PlottableList.Add(logger);  
WpfPlot2.Refresh();

However, it seems there is no direct API to attach an existing DataLogger to a different Plot.
Is there a recommended way to do this? Or would it require recreating the logger and copying its data manually?

Use case: I want to toggle between different views that share the same live data source without duplicating the data unnecessarily.

Thank you!
