Characteristics cannot be seen in the dashboards if they are present in the column of the report.
Reproducing the Issue
Steps to reproduce:
1. Go to Analysis Work center and select Dashboards.
2. Open any dashboard which has characteristics included in the columns instead of rows.
In dashboard you can only see the key figures in the columns of the report but not characteristics.
This is system designed behavior. Characteristics are currently not supported in columns for HTML5 dashboards.
Additionally, Key Figures are also not supported in rows for Dashboards in HTML5. This was addressed on RUI.
This have been enhanced in Responsive UI and you should be able to visualize characteristics in columns on RUI mode.
