Would be really nice if there was a way to synchronise the axes of multiple plots. I've tried doing it using the AxesChanged event, but the result doesn't feel responsive and the performance is underwhelming.
I propose implementing the ability to add multiple plots to the control (FormsPlot in WinForms) or making a new control with this functionality. There should also be an option to sync the axes, something like

formsPlot1.SyncPlotAxes(horizontal: true, vertical: true);

Then, instead of accessing the plot using formsPlot1.plt, it would go something like formsPlot1.Plots[0]
