using Plots gr()
Plot multiple series with different numbers of points. Mix arguments that apply to all series (marker/markersize) with arguments unique to each series (colors). Special arguments
fill will automatically figure out what arguments to set (for example, we are setting the
color arguments with
line.) Note that we pass a matrix of colors, and this applies the colors to each series.
plot([rand(10), rand(20)], color = [:black :orange], line = (:dot, 4), marker = ([:hex :d], 12, 0.8, Plots.stroke(3, :gray)))
