By default, a chart will filter out any items that extend beyond the defined min/max ranges. If you set filterData=false on the series, it will render all items, regardless of how they fit in the ranges. It will still clip the data region of the chart, so they won't extend beyond the visible area. Keep in mind that this means that if you have lots of data that falls outside your defined range, and set filterData to false, you will still pay a cost for processing them and getting them into the display list, even though they don't show up on screen. You'll want to keep an eye on performance and see if you need to take action to explicitly filter the data yourself by hand. (A middle of the road option...'filter data that falls completely outside the min/max, but include data that overlaps it.' Would be a nice enhancement.

From: [email protected] [mailto:[EMAIL PROTECTED] On Behalf Of Mark Sent: Friday, August 31, 2007 11:26 AM To: [email protected] Subject: [flexcoders] DateTimeAxis on BarChart needs tweeking I have a bar chart that I'm using to display a start date and end date for each project in my XML. It works great but when I add minimum and maximum values to the DateTimeAxis the records that don't fall between that minimum and maximum values don't show. In other words - the projects start and end dates must fall between the minimum and maximum values, no overlap on either end. If either one overlaps it won't display the bar. I need the bar to show as long as either the start or end date fall in-between. My guess is I have to write a custom itemRenderer for the bar changing the value, but I'm not sure how to get the minimum and maximum values from within the itemRenderer. Any ideas on any of this? Thanks
