[f1nir_]

I've create a simple example for my question and its on jsFiddle. Basically I want to have two things: [*]reflow the size of the chart to fit its container when window is resizing; [*]reflow the size of chart to fit its container when the resize bar is movingNote: I am using jQuery UI layout plugin for layout management and I have no clue how to handle resize event with a moving resize bar. I've working on this for long and still looking for answers about this. Thanks anyone providing comments or suggestions.
