Problem:
For a visualisation of data from a DAQ-system I have my data in some classes doing the daq, calculation, datahandling, saving,... There my data are in List<double> as this is for me much easier than using double[] and increasing and copying the array from time to time. I had it this way, before I found the possibility to use List<double> in Scottplot5.
The lists for X and in the case of not equidistant signal sources timestamp Ys are growing by time. Existing data are not changed.

And then I'm using a SignalPlot for displaying
thePlot = plot.Add.Signal(ys:dHandler.data[fqVarName].valList, period: ((clsDataPeriodic)dHandler.data[fqVarName]).dt);

Now I wanted to extend my possibilities with SignalXY for non-equidistant x-values but there as datasource only double[] or T[] is possible.
(SignalXYSourceDoubleArray and SignalXYSourceGenericArray)
I would need a
plot.Add.SignalXY(ys: dHandler.data[fqVarName].valList, xs: ((clsDataUnevenly)dHandler.data[fqVarName]).timestampList); to use my existing Lists of doubles.

Question:
Is there a way to use "external" List<double> as the x and y data of SignalXY? The effort to rework everything to double[] would be pretty high.

Possible Alternatives?
Doing a List<double>.toArray() 3-4 times a second before a plot refresh should work, but this will most probably bring me into performance issues I think. Depending of the measurement time and sample rate I have from 0 to some 100 Mio doubles in the List<double> per signal.

1. mySignalXYPlot.Data = new SignalXYSourceDoubleArray(valueList.toArray(),timestampList.toArray())
2. WpfPlot.Refresh()

DataLogger?
In some other small programs I use DataLogger. Would it work to store the public List<Coordinates> in my dataHandler? Until now I used only the Add() method of the data handler.

ScottPlot Version: 5.0.54
