Hi,
and the output that i am expecting is
Please let me know which command needs to be used and also reference books for learning development, I am completely new to Splunk
For SimpleXML dashboards, add a format block to the table with the useThousandSeparators option
https://docs.splunk.com/Documentation/Splunk/8.2.2/Viz/TableFormatsXML
<format type="number" field="count">
<option name="useThousandSeparators">true</option>
</format>
Thank you @ITWhisperer for suggesting the method of using XML .
I have tried with the command (chart count by "Online Booking") gives me the accurate search result and also tried with XML and my dashboard looks quite good.
