Sending alert based on Threshold conditions

[sajug]

Hello
I have query that gets me x values every 5 minutes. Now what I am trying to achieve is, alert based on threshold conditions. For example

index=xxx | timechart span=5m eval(round(avg(x),3)) as xvalues

Condition for alerting below

xvalues<100 no alert
xvalues>100 and <200 - Warning alert
xvalues>200 Critical

Thanks in advance

Oops I was not aware the editor does not support certain symbols. So here are the alerting conditions again

xvalues<=100 no alerting
xvalues>100 and <=200 warning
xvalues>200 - Critical Alert
