Title: bar chart with error indication

Barchart will indicate an iteration error in an experiment with a red bar.

Current limitation:
- Hovering over a red bar will trigger a tooltip to show the error message, however, currently the data model does not contain any error message, so the tooltip will always show 'Null' as error. The limitation should be resolved once the data model design is improved.
