#37761

@scroteau,

rangeChanging event is fired when the range of the chart is about to be changed i.e. just before rendering of the chart with updated viewport values. While rangeChanged event is fired after the chart is rendered with updated viewport values. With help of dynamicUpdate in StockChart, you can control when to fire rangeChanged and rangeChanging events. If dynamicUpdate is set to true, then range of chart will be updated at every movement of handle and hence rangeChanging and rangeChanged will be fired on updated viewport values. When dynamicUpdate is set to false, the range of the chart will be not updated at every movement of handle but rather will be updated when you release the handle. So rangeChanged and rangeChanging will be fired only on release of handle.
