The radiusField property is the field in the data provider that will be used to specify the radius of the bubble.
It can't be set to a number, it is the name of a field.
You really want your charts driven by data sets, so use this property to specify the data field for the radius.
If this answers your question or helps, please mark it as such.
Greg, in my example when the Dataset (arrayCollection for variable s1) r value is 0.50 and the Dataset arrayCollection for vairable s2) r value is 0.50, the Bubbles drawn on the chart are very small. Is there a way to make the Bubbles drawn larger, as when the r value for s2 is 0.70?
Wow, that's really strange. I wonder if that is a bug.
Greg, I think I have solved the issue. I am using the minRadius and maxRadius properties for the BubbleChart and have set them with values 40 and 60. Now when both the radius fields are the same value for my datasets, I am able to see much larger Bubbles drawn.
Glad you worked it out.
