ADF DVT: Stack Bar Graph unable to display all Bar.

Question

Hi Experts,
I'm currently having a problem displaying bar graphs in my Use Case.
There are unavoidable instance that at some point of the information provided, there may be part that contain a very huge data.
Below is my sample code.
In the example code below only the detail with huge data is rendered in the graph. and the rest are not rendered. is this  a known issue?

I'm using ADF PS6 in windows7(64bit), Chome browser.
ManagedBean. This bean contains static data for testing only. Notice how big the data in the 2nd to the last detail.

Achie,
This is not an issue with the graph as such, but the data issue. Since the value of the data that is being displayed is huge and other datas are relatively very small to occupy the graph area (Ex : 60105 Vs 10).
You may want to try implementing zoomListener and/or zoomScrollListener for the graph to zoom and see the small datas.
