If you only want simple line graphs, it can be as simple as making a linked-list of (say) the last 100 measurements and then deriving your own drawing box (from Fl_Box) and in the draw() method of your widget, just plot the data. Then use a Fl_Timer to gather a new sample every (how often?) and then trigger a redraw of the plot. The challenge of figuring that lot out might make it worthwhile doing... However, if you just want a basic plotting widget... I went to the FLTK site "links" page and typed "graph" in the search box; got a fair few hits (many of which don't look useful!) Of those that do look useful, Roman Kantor's Cartesian widget (http://rfltk.svn.sourceforge.net/viewvc/rfltk/cartesian) is a good choice, and there are many others, e.g. http://www.kiwacan.co.nz/fltk/index.html and so on... See http://www.fltk.org/links.php and search from there, see what comes up, sure to find something that works for you! ******************************************************************** This email and any attachments are confidential to the intended recipient and may also be privileged.
