If all of your indices have a similar name and mapping, then you can group them into a single index pattern, and use that single pattern within the visualization.
All Kibana visualizations are based off of index patterns, which are groups of one or more indexes. So as long as your indexes can be grouped into a single pattern, then this will work just fine for you. For more information on index patterns, see our guide here: https://www.elastic.co/guide/en/kibana/current/tutorial-define-index.html
