it do not work in Comopnent

[puchunjie]

i instantiation it in 'ready' cycle，But it doesn't work properly。 in 'Page' It's normal.

[cougarwww]

when new wxCharts add a new arg like ： componentInstance: this,

wecharts line 1856 like this
this.context = wx.createCanvasContext(opts.canvasId, opts.componentInstance);
