Catch events fired in a panel from a different panel

Is it possible to catch an event fired in a panel (for example, the graph-hover event of graph panel) from another panel (for example, the AJAX panel) with all of the original panel’s data (like datasource, query, etc.)? In my case, I’m trying to make a pseudo-tooltip for graphs from Influx datasource with the AJAX panel.

No this data is not available in that event.

Then is it possible to get those data from a panel from another panel at all, in any way?
