Labelling functions in Gadfly plot

Plotting functions directly is easy in Gadfly:

plot([sin, cos], 0, 25)

This gives my two differently colored lines, automatically labelled in the legend as something like f_1 and f_2:

How can I change the default names in the "Color" legend?

Solution

  • Set the color argument to a list of labels:

    plot([sin, cos], 0, 25, color=["sine", "cosine"])

    Update labels
