I'm sorry, when I said labels weren't implemented yet, I meant the legend. You may find an example use of labels in the "Text_labels" test. You can place the legend manually using Viewport.text using the `Graph or `Device coordinates (normalized coordinates of resp. the graph window and the viewport) and playing with paths for making your legend box. For example, you can place the text with: Viewport.text vp ~coord:`Graph 1. 1. ~pos:Backend.LB "Banana"; >> For instance on >> Food 2000 2001 2002 2003 >> Banana 4 5 5 2 >> Lemon 1 2 3 4 >> Orange 2 2 1 3 >> >> What would be the call to Archimedes.stack ... >> to get the stacked bars with the right labeling and not too bad color (let's >> say red/green/blue for banana/lemon/orange). I invite you to check the latest bazaar trunk and take a look at the test "Plot_stack" where you set the style to `Lines with : A.Array.stack vp ~style:`Lines data; If the predefined colors doesn't suit your needs, you can specify your own array of colors via the ?fillcolors optional. If you have further specific questions on the use of Archimedes, I invite you to discuss them offlist. Thank you for your interest in Archimedes, Pierre Hauweele -- Caml-list mailing list.
