SAPUI5 dynamic creation of timelines does not work properly

I have a table, which is generated dynamically and when I mark individual lines and click on a button, it generates me in a dialogue window several history diagrams. My problem is that the data is transmitted correctly but many diagrams are left blank and some are working properly and I'm at a loss as to why it is. The object consists of dates but not every fatum there is a value. A working:
