Got container width error while using Annotated Timeline chart in GWT

[ALEX ZHAO]

I got following error while trying to add an Annotated Timeline chart in an existing GWT TabLayoutPanel.

(Error): Container width is zero. Expecting a valid width.

However, if I did not add the chart in an existing TabLayoutPanel, but put it in popup DialogBox, it worked.

Anyone knows the reason? Thanks a lot in advance.

You need to set a height/width when you create the chart object:

AnnotatedTimeLine chart2 = new AnnotatedTimeLine(data, createOptions(), "800px", "600px");
