Line chart doesn't show in Object Page - Vizframe - SAPUI5 - charts

Question

I am trying to make a line chart using Vizframe in an Object Page. Does anybody have an example how to do it? I searched the APIs and the sdn but find just samples with Layout element and not Object Page Layout element.
So when I test it within a simple Layout element (< layout > element) the line charts works fine. But when I try it with Object Page Layout elementt, the chart doesn't show and there is no errors in the console.
Thanks a lot,
Haylee N.
I joined the two different views here:
View.xml with Layout element ( that works )

Answer 1

Whoever may come here for an answer, giving the height of vizframe with pixels does the trick.

Answer 2

As pointed by people in this question some controls use adaptive containers that adapt height to fit their content. If that content uses "100%" of height (which is initially 0) the content efectively becomes 0px and those controls end up adapting their hight to 0px height of the content. For the same reason if you use fixed height instead of a percentage it actually works.
For me personally, this problem only occurred because I blindly copied sample code for VizFrame into IconTabBar container, without realizing the difference in containers used.
Solution to my problem: remove the height="100%" property from VizFrame, which will not force height and in turn will allow the height of VizFrame to be calculated based on its content (title, actual chart, legend and such), instead of container that VizFrame is placed into.
