Line plot

Multiple lines with a legend – the plot reference example. The third line adds marker= – a dot at each vertex alongside the line itself, sparse data over the same 200-point grid so the individual markers stay distinguishable rather than merging into a solid row of dots.

Live figure — pick a tool, then zoom, pan, point-pick or annotate. Nothing is active until a tool is selected.
