Two questions: 1. In a Haskell program, if all I want to do is output an image, like a graph or chart, what is the simplest library to use? N.B. Simpler := easier to get minimal functionality. I really don't want to wade through a bunch of boilerplate or climb a steep learning curve just to be able to plot a few lines or circles. 2. Suppose I want interactivity. For example, I want to plot a line graph, and then let the user click and drag the data points. From what I understand about GUIs, I would need to track mouse buttons (up and down), mouse movements, and possibly keystrokes. (I know this is the complete opposite extreme from my first question) In this case, what would be the best (not necessarily simplest) library to use? What would you recommend?

OK, Chart (the first package under Graphics) is obviously the answer to (1). I wrote:

So I have a choice: OpenGL, HGL, SDL, ObjectIO(?), or even straight X11/Win32 :/ Let me ask both ways: 2a. Which of these (or perhaps something else) is the simplest/easiest to get started with? 2b. Could someone please point me to some advice to help me decide which of these would be the best for me to use. I'm just trying to avoid the need to invest gobs of time into investigating libraries.

I would go for GL(U(T)), as it's as good for 2d primitives as SDL will ever be, has excellent cross-platform support and allows you to go 3d if you want to. There's also some very decent event handling. -- (c) this sig last receiving data processing entity. Inspect headers for past copyright information. All rights reserved.

You can use R as well. http://www.r-project.org/ -- yann@kierun.org -= H+ =- www.kierun.org PGP: 009D 7287 C4A7 FD4F 1680 06E4 F751 7006 9DE2 6318
