How to Create a scatterd graph?
can we use buuble graph or Plot Graph of Flex?

Requirement is like there were two values x and y.
So (x,y) = (10,20) , (10,22), (10,23), (11,23) etc
for each point there will be a dot.

Some of your demos fit neatly into what we want to do buT i am a bit stymied by lack of doco e.g. How do I write a data renderer thta changes the colour of a bubblechart datapoint based on a function (eg countries in america are blue, countries in Europe are green etc). Second your demo of zooming axes (can't get them to pan) is good but it no longer displays the axis title. Is there more detailed doco about how to subclass the chart components?</p> Just starting to look at Flex charting for work.

I'm using . The item renderer's getFill method ignores any threshold with a binded value. in the Flex Language Reference shows a working example of using outerDocument. I assume the problem has something to do with the qc namespace, but I haven't found a way around it yet. Any ideas?</p> This is very useful information, and repurposing the code to render items in a plot chart was easy enough until I tried to use dynamic data for the values of StopLightThreshold.

A custom renderer like this would be a quick and dirty way to get that kind of a render. But to do that right, you'd probably want to add an extra axis of data to the series itself (which is how the bubbleSeries does it). Assuming you have an abitrary range of data, you'll need to compare all the values in the chart to figure out what the max and min is and scale them appropriately, which is what the axes are for. If you have a fixed min/max that you know your data will fall within, you could just take this code, look up the extra data value you care about, , divide it by your max, and use that fraction to scale the radius.</p> <p>Also, if you want labels on the chart, you'll need to extend the series to make sure they pick up the adjusted wedge values.</p> <p>I'll see if I can throw an example together to get you started.</p> Hi Martin.

Also, if you want labels on the chart, you’ll need to extend the series to make sure they pick up the adjusted wedge values.

I’ll see if I can throw an example together to get you started.

(similar to the radiusField in a BubbleSeries)</p> Would this serve as a good starting point for a renderer that renders each wedge with a potentially different radius?
