No. You would need to redraw/render the whole chart with full set of updated data.
FuisonCharts for Flex, as of now, does not support dynamic scaling or resizing when the container resizes. Our future version would support this feature.
FusionCharts for Flex can accept data from simple XML file, XML string to Flex data types namely, Array, XMLList and Model. However, FusionCharts internally accepts only XML data.
Not directly. You can use your own Flex code to build XML, or other types of data sources that FusionCharts for Flex supports, and pass it to the chart. In our future releases, this feature would be available.
