the groups-matrices(according to template.yaml) can use old auto-group-compare mode, get average/stddev/change value result as bellow:
4k|1G
openeuler 20.03 debian sid metric -------------------- ------------------------------ ------------------------------ %stddev change %stddev \ | \ 308298.55 ± 12% -28.5% 220289.08 fio.write_iops
next, we can create json result for echart.
