RE: [flexcoders] gant chart

[Andrew Trice]

You could create itemrenderers for a datagrid that utilize the drawing API to draw the horizontal lines for your data.   For instance, have a grid like this:   Column 1: task name Column 2: duration Column 3: start date Column 4: item renderer that draws out task length with respect to width of column.  Use the drawing api to draw lines/rectangles to represent a duration of time.   You could also have a custom datagrid column header that uses the drawing API to draw a scale for the time shown in column 4.      Using a datagrid component for this also keeps it very easy to get data into your Gantt chart.   _____________________________________ Andrew Trice Cynergy Systems, Inc. http://www.cynergysystems.com   Blog: http://www.cynergysystems.com/blogs/page/andrewtrice Email: [EMAIL PROTECTED] Office: 866-CYNERGY    From: flexcoders@yahoogroups.com [mailto:flexcoders@yahoogroups.com] On Behalf Of Iko Knyphausen Sent: Friday, October 20, 2006 3:58 PM To: flexcoders@yahoogroups.com Subject: RE: [flexcoders] gant chart   There is a flash component out there (http://www.anychart.com/products/anychartgantt.shtml). I have emailed them with some questions, but have not yet received a response. If you know others, please let me know. I would be quite interested in such a chart for my flex apps too...   I have written a Gantt in DHTML and _javascript_ and it’s not entirely trivial. It also depends on the kind of features you want to offer, for example dependency lines, summary tasks, task progress, time line scale, just to name a few.   At the time, I wrote a container and then added task objects on the fly. The container would know how to render the task objects, and the task objects themselves carried their information such as start and end date, dependencies, progress status, etc. If your chart is supposed to be interactive, you should also offer some events to be raised: e.g. Task was clicked, dependency was dragged, chart was scrolled down (so that you can connect the chart to a grid and scroll them in parallel). As you can see, it quickly gets complex.   There is another company that offers interactive Gantts, ILOG (http://www.ilog.com/products/jviews/gantt/   ) but I am not sure what they offer in terms of licensing and whether they will offer anything in the flash/flex space.   Hope this helps -Iko From: [EMAIL PROTECTED]ups.com [mailto:[EMAIL PROTECTED]ups.com] On Behalf Of arnold_charming Sent: Friday, October 20, 2006 12:27 PM To: [EMAIL PROTECTED]ups.com Subject: [flexcoders] gant chart   Hello!
