Console error when with wrong #:legend-anchor in plot #305

Open gus-massa opened 5 years ago

If you run this program in DrRacket(in Windows), where #:legend-anchor is a string

#lang racket
(require plot)

(plot (points '((1 2) (3 4)))
      #:legend-anchor "Hello")  ; <-- wrong type

you get a graphic. But if you move the mouse over the graphic it opens the console with an error
