I have a simple question, I'm using ELK stack to plot some graphs with data from my logs. Now if the metrics I'm logging stopped sending to Elasticsearch and the queries are getting no values for certain time-windows, then my graphs are empty. Is there a way to set the values to 0 for these metrics when they're missing in Elasticsearh? ---
