Hello, I am trying to do graphs with multiple layers with Gadfly. I have a dataframe with many columns, one "x" and a lot of "y"s, and I want to plot this in a single graph.
For two layers, I have the following:
plot(df, layer(x="x", y=df[2], Geom.line), layer(x="x", y=df[3],
Geom.line), Guide.xlabel("k")),
but if my dataframe has *dozens* or *hundreds* columns, what I should do to
plot this in a single graph?
Best,
Leandro.
