[Why] With template compare mode, it's not friendly for echart that return null for nil standard_deviation of a metric like: { "tables": { "vmstat.system.cs": { "standard_deviation": { "dimensions": ["compare_dimension", "openeuler 20.03"], "source": [ ["4G", "8G", "16G"], ["openeuler 20.03", 23, null, null] ] } } } } [How] fill 0 if standard_deviation is nil.
