"2018-10-02T00:00:00Z", 56.25
"2018-10-03T01:50:00Z", 58.35
"2018-10-03T05:20:00Z", 65.15
How to get the result as sum of sales group by date

Use a term facet with a nested aggregation facet.
Try
http://xx.yy.xx.zz:8983/solr/mycorename/select?fl=eventTimeStamp%2Cevent1&group.sort=event1%20desc&group=true&q=%3A&group.query=eventTimeStamp:[2019-08-01T00:00:00Z%20TO%202019-08-01T23:59:59Z]&group.query=eventTimeStamp:[2019-08-02T00:00:00Z%20TO%202019-08-02T23:59:59Z]&group.query=eventTimeStamp:[2019-08-03T00:00:00Z%20TO%202019-08-03T23:59:59Z]
Above query can be helpful for you. And use json-facet-api for sum.
