Easy Chart Start Data Binding paramters useless?

When I open this poup
window = system.nav.openWindow('PC/PopuPCChart', {'startDT':startDT,'endDT':endDT,'title':u'曲线'})

Easy Chart Start Data Property Binding with paramters useless?

The startDT and endDT not change to the parameters....

Yes, sorry.

The EasyChart rejects property assignments to start/end that would make the range invalid (reversed, whatever). Bindings don't have a defined delivery order, so breakage occurs. A scripted assignment, with order checking, is typically required.

Easy Chart ----Scripting--- configChart
Then it's right!

self.startDate = self.parent.startDT
self.endDate = self.parent.endDT
