I am trying to sync up 2 panels that uses the same search but shows different visualization (e.g. bar chart and pie chart). It will auto refresh every 30 seconds and I want both panels to refresh at the same time.
One possible solution is to do a dashboard refresh instead of a panel refresh. However, I have many panels in this dashboard and it will take up significant time and memory to finish loading every panel if it is all refreshed at once.
Is there any other solution to sync up both panels' refresh time?

Since both your panels use the same search, you can utilize the post-process feature to run the search just once.
