I'm asking this question because the only solutions I find for this problem are with the XML config file, while I only have access the JSON source code. I've looked at the recent Splunk documentation and there doesn't seem to exist a depends field for the visualisation configuration in the JSON source file. I'm trying to achieve the hiding of a specific panel if a dropdown choice isn't selected. Any help would be appreciated. Thanks.
Presumably you are talking about Dashboard Studio - my understanding is that this type of panel hiding/dependency is not a feature of that yet.
