CodePudding user response：

This is probably the Unicode for greater-than that is not reflected properly. You should try with the following in Log Analytics:

AzureMetrics
| where TimeGenerated >= ago(90d)
| where Resource == 'MyDB'
| where MetricName == 'full_backup_size_bytes' // in ('full_backup_size_bytes','diff_backup_size_bytes','log_backup_size_bytes')
| make-series SizeBackupDiffTB=max(Maximum/1024/1024/1024/1024) on TimeGenerated in range(ago(90d),now(), 1d)
| extend (RSquare,Slope,Variance,RVariance,Interception,TrendLine)=series_fit_line(SizeBackupDiffTB)
| render timechart
