Hi There,

Is it possible to show the value zero instead of ! symbol in Canvas. if the returned document value is zero.

Thanks,  
Raj

Something else is going wrong, there. Can you paste the error message itself? Are you maybe dividing by zero or something like that?

Thanks Chris For the reply for example this expression

filters

| essql

query="SELECT COUNT(DISTINCT fname.keyword) as client\_ip

FROM "nessus-\*" WHERE QUERY('risk\_factor.keyword:Critical') AND "@timestamp" \> NOW() - INTERVAL 24 HOURS AND "@timestamp" \<= NOW () "

| math "client\_ip"

| metric "Unique Count of IP - Crtical Risk"

since the result is zero i dont get any values

for example I have extended the time frame to 7 days for example

filters

| essql

query="SELECT COUNT(DISTINCT fname.keyword) as client\_ip

FROM "nessus-\*" WHERE QUERY('risk\_factor.keyword:Critical') AND "@timestamp" \> NOW() - INTERVAL 7 DAYS AND "@timestamp" \<= NOW () "

| math "client\_ip"

| metric "Unique Count of IP - Crtical Risk"

since the result is 1 , I get the value

I have attached the screenshot ![nessus_exp](https://us1.discourse-cdn.com/elastic/original/3X/2/d/2dd592e21152da6180e5811c1ccf2856f25869ba.png)
