Answer 1

您可以使用(defun scatter (lists) (eazy-gnuplot:with-plots (*standard-output* :debug t) (eazy-gnuplot:gp-setup :terminal '(:qt)) (dolist (cluster lists) (eazy-gnuplot:plot (lambda () (dolist (point cluster) (format t "~&~A ~A" (first point) (second point)))))) (format t "~&pause mouse button1;~%"))) 。我使用了paste()数据集并添加了一个换行符。
