Can't Visualize data in the dashboard but only in the Visualize

Elastic Stack Elasticsearch
1

Hello, I can't see the data in the dashboard. It always appears No results found, but there is data with te filters applied. I have seen in the Response tab and I get "reason": "ElasticsearchException[org.elasticsearch.common.breaker.CircuitBreakingException: [FIELDDATA] Data too large, data for [@timestamp] would be larger than limit of [623326003/594.4mb]];

How could I change this limit for being able to visualize all the visualizations in the dashboard?

I think that I have too much in the cache.
I have left the default parameters for ES_MIN_MEM , ES_MAX_MEM and ES_HEAP_SIZE..
Now my question is... I should change the ES_HEAP_SIZE to the 50% of the total RAM memory? (4 GB) or only 50% of the free
