Patricia, The obvious way to do this is to use JavaScript to compute the new positions of the bars, and set the value of a transform attribute on a <g> element. A more clever way to do this is to make the bars glyphs in an SVG font, then write out the graph as a "text" string. Since the relative positions of successive glyphs are automatically computed for you, your JavaScript only needs to add and remove characters from a text string when the +/- button is clicked.

Importance: Low Hi, all: Apparently, my subject line didn't contain enough information. Sorry about that. So, I've included my previous message here and more detail below. Okay, I'm ready to research and learn how to do this but I need an expert opinion on the best way to do this or if this can even be done. I have bargraphs of parent tasks and bargraphs of child tasks associated with the parent task bargraphs. My boss wants to have a +/- clickable image to show child task bargraphs when the + sign is clicked and hide child task bargaphs when the - sign is clicked, much like a tree structure only for bargraphs instead of text. I know I can set visibility to hidden but that will not remove the horizontal white space that will occur as a result of hiding the bargraphs. Thanks, again, for your time, Patricia [Non-text portions of this message have been removed] ----- To unsubscribe send a message to: [EMAIL PROTECTED] -or- visit http://groups.yahoo.com/group/svg-developers and click "edit my membership" ---- Yahoo!
