Hi,
I have data with field names in the format:
h00m00 h00m15 h00m30 h00m45 h01m00 .. thru h23m45
I'd like to pull the 'h' value from a drop down and use that in a chart command , so eval hh=substr('04:00:00',1,2) from the current token in the drop down should give me 04.
Then somehow chart just the h04* fields so I can focus on a specific hour as below where I hardcoded the h04*
| chart sum(h04*) by edate
if anyone has any ideas I'd be grateful.
The first part before the blank lines in the search query just generates the fields you suggested. The important bits are evaluating the token in the dropdown and using the token in the chart command.
<panel>
<input type="dropdown" token="hour" searchWhenChanged="true">
<label>Hour</label>
<choice value="00:00:00">00:00:00</choice>
<choice value="01:02:00">01:02:00</choice>
<choice value="04:05:00">04:05:00</choice>
<change>
<eval token="times">"h".substr($hour$,1,2)</eval>
</change>
</input>
