Sorry for late reply, didn't get the notification

how can i have different values listed instead of top values?
If you want to have a finer control over your values rather than just letting Lens picking up the "Top values" you can use Filters, but then manually define all the possible values. This could be probably a better case for also the second question:
In the example above I've created a query for each row using Filters and the last one is 0 as there's no match found.
