In discover mode, you can create a query that filters out the events that does not have "IsLatest" set to "Yes" and then save this. When you build your visualisation, you should be able to base it on this filtered query instead of the unfiltered one to get the result you are looking for.
in discover tab you can do this querry-search : _IsLatest=Yes
Then you will see that this brings you all the docs that have IsLatest field equal to "Yes".
If you want to plot (count plot for example) these docs you can use the same search in visualize tab.
