Druid / JSON - graph show only the first/oldest result entry of the result set

Hi all,
I try to connect grafana to druid - the connection is working and I get results back (list of json objects) but the graph show only the first/oldest “sum_value” e.g. 192.

Any Idea?

Result set:
“response”: [
{
“timestamp”: “2018-11-25T16:49:00.000Z”,
“result”: {
“pagingIdentifiers”: {
“sensor_md_v8_2018-11-25T07:42:00.000Z_2018-11-26T00:00:00.000Z_2018-11-25T15:49:49.053Z”: 2
},
“dimensions”: [],
“metrics”: [
“sum_value”
],
“events”: [
{
“segmentId”: “sensor_md_v8_2018-11-25T07:42:00.000Z_2018-11-26T00:00:00.000Z_2018-11-25T15:49:49.053Z”,
“offset”: 0,
“event”: {
“timestamp”: “2018-11-25T16:49:01.795Z”,
“sum_value”: 192
}
},
{
“segmentId”: “sensor_md_v8_2018-11-25T07:42:00.000Z_2018-11-26T00:00:00.000Z_2018-11-25T15:49:49.053Z”,

}
},

}
]
}
},
