I've been lookikng for a similar chart type and haven't yet found one. I was just about to write one myself. What I need - and what I think you are asking for - is like an x-y scatter plot with lines between the data points. This chart type is available in Excel and I use it a lot for irregularly spaced x-axis line charts. Typically the x-axis is a date.
The difficulty seems to be that the x-axis has an irregular interval. Flex Line/Bar charts expect that the x-axis is either a discrete integer or a category. Chart types that have a continuous x-axis, such as the bubble chart, don't support drawing lines between the data points. If you treat dates as categories (which is the only option available in flex if you want a line chart) then you lose a lot of information about the (ir)regularity in the data and it can make the chart quite misleading. I have tried a custom item renderer for a bubble chart but it was very messy - maybe I just needed to spend more time thinking about my implementation, but it didn't feel right that the item renderer knew about its adjacent data points, and then I had z-order issues when drawing lines. It would be really good to have one of the charting experts who post here make some suggestions. --- In flexcoders@yahoogroups.com, "donvoltz" <[EMAIL PROTECTED]> wrote: > > Hello Everyone, > > I have been digging into the flex charting components with nice > success.
