I wish to plot graphically a function using MIT scheme. In the manual of scheme, there is a section called "Graphics" -- quote:
MIT Scheme has a simple two-dimensional line-graphics interface that is
suitable for many graphics application.
If you experienced this, please help me by pasting a minimal working code (KISS principle) that works with MIT/scheme, and which plots something.
It looks like this manual contains documentation of each individual function, but full out examples of every function do not appear to exist in any documentation online. The only way I was able to find working code was to Google the actual function names and arduously review each result for possible code samples.
Anyway, to satisfy your question and give you a simple example of how this library works, here is sample code.
(let ((device (make-graphics-device (car (enumerate-graphics-types))))
(x-start 0)
(y-start 0)
(x-end 5)
(y-end 5))
(graphics-draw-line device x-start y-start x-end y-end)
(graphics-close device))
If you need more samples, let me know, but the code and docs should be enough to get you going.
