Yet another FAQ, without a doubt.
Does anyone have a graph widget that will do multiple line and/or bar
graphs on the one surface? I am looking for fairly basic
business-type graphics.
I have seen graph.tar.Z from trix.ai.mit.edu (as named in the X FAQ
list). It seems OK, but only one line graph at a time, and no bar
graphs (from what I can tell; there is no documentation...)
What would be ideal is the ability to have a hierarchy of widgets,
with a container widget that is the graph, does the scaling etc and
there is one child for each dataset on the graph. This would allow
setting line colors/styles etc as resources without imposing fixed
limits on the numbr of data items (I think...).
Greg.

Anyways, to answer your questions: graph.tar.Z on trix.ai.mit.edu has been updated. It DOES do many line graphs at a time and always did (i.e. you can call graph_add(), graph_add_array() etc.. multiple times). It also has a rudimentary histogramming capability. (try setting *graph*histogram: true -- Ok. It doesn't use flashy tiles -- it just draws rectangles). I also included a doc/doc.tex file which is a version of the documentation that still hasn't quite caught up to the code. :-) New resources that aren't documented: *markpoints: Bool (says if points should be highlighted) *pointstyle: String (one of square, hatch, box) *histogram: Bool As usual, send bug reports/suggestions/enhancements etc. to me.

Your suggestion is valid but to me sounds like you're confusing requirements with implementation details. Another implementation approach would be to use an OO graphics library (such as the one in InterViews) and extend it to have a bar_chart_graphic, pie_chart_graphic etc (each of which is a subclass of, say, graph_graphic). Using this approach, each graph would be a graphic rather than a widget (window). The advantage is that it would be easy to overlay several graphs. (If each graph were a separate widow/widget then overlay one on another would obscure the lower one.)

If nobody sends one, and you need it now, you could hack the scrollbar, or even the label widget to do bar graphs.

I'm looking for the same thing - simple, nitwit-level graphics (histograms, (yuk) pie charts). I've looked at "graph" on trix and it doesn't seem to fit the bill. Any help would be greatly appreciated! THANKS!
