If you add a simple staytime table chart by clicking on the statistics of a zone and then selecting the staytime pin, the table shows also instance and the statistic columns. In my opinion these clutter the graph and are only necessary in specific situations.
To get rid of them you can install the graph and then there are checkboxes to switch those columns off:
It would be nice to have those checkboxes also already in the default option so these extra 2 columns can be switched off easily without installing.
