What is the order of filters

Hi, we are exploring grafana to use against the splunk plugin and the connection is successful. But 1).we noticed that when we pull large volume of data into grafana panel it breaks - tried to use query options to raise the data points value but not helpful
2).another question on filters - splunk search query has filters set as earliest=-7d@d and latest=now() - in grafana on the right hand side if i select last 2 days - will this overwrite the 7 days which is in the query

what happens when you run that same query in splunk?

in splunk it works fine no issues with the data volume - this is so frustrating all of a sudden it says something wrong in the plugin

can you trim the data coming back to just what you need for the dashboard?

Also can you run the same query using splunk rest api?

Yosiasz, what about the filters that are in the query - and the timerange filter that we select in grafana on the right hand side - if my query has the filter like earlist=-7d@d and latest=now()
but i selected only 1 day in the timerange filter in grafana - what happens in this case - sorry it might be very basic question
