How to rename label in splunk legend that not effected the lookup name?

Hi,

I would like to display each plugname on the legend instead of plug1, plug2, plug3 and so on using timechart.
I was able to display plug1, plug2, plug3 as a lable name and so on, on the chart legend, but couldn't get the plugname for each plug to display on the legend.

How to rename or show a label in splunk legend to show the dynamic plugname when performing a search.
Please looking forward to your help to resolve this problem.

Below is the JSON code that send to Splunk:

In addition, next step I would like to be able to click on individual plug name on the bar chart or from the legend label for the drill down details. As of now when I click it. It said no result found. Please I really need help and thank you in advance.

Hi woodcock,

In addition, I would like to be able to click on the legend label for drill down to see individual activity current occur per plug name.

Here is my search string

| search siteid=$siteid$ location=$location$
| foreach powerdata{}.plug*{}.* [ eval eachplug<> = mvappend(eachplug<>, "<>=" . '<>') | fields - <> ]
| foreach eachplug* [ nomv <> | eval allplugs = mvappend(allplugs, "plug=<>, " . <>) | fields - <> ]
| mvexpand allplugs
| rename allplugs AS _raw
| kv
| timechart limit=0 max(voltage) AS max_voltage BY plugname

The bar chart work great as expected, but need to be able to click on a single legend for the drill down on the bar chart. I don't know how to do it.

This approach rearranges each single event into multilpe events, one for each plugname. From there you can do anything easily.

I got the warning message on my bar chart said Field 'allplugs' does not exist in the data. Only when I select individual siteid and location from my drop down.

when using this search string on my dashboard

| search siteid=$siteid$ location=$location$
| foreach powerdata{}.plug*{}.* [ eval eachplug<<MATCHSEG1>> = mvappend(eachplug<<MATCHSEG1>>, "<<MATCHSEG2>>=" . '<<FIELD>>') |  fields - <<FIELD>> ]
| foreach eachplug* [ nomv <<FIELD>> |  eval allplugs = mvappend(allplugs, "plug=<<MATCHSTR>>, " . <<FIELD>>) |  fields - <<FIELD>> ]
| mvexpand allplugs
| rename allplugs AS _raw
| kv
| timechart limit=0 max(current) AS max_current BY plugname

But when I select ALL from my drop down the warning working great.

How to bypass the the 'allplugs' when not selected ALL?

Must be a problem with your dashboard tokens.

Never mind the warning just went away now. Thanks for all your help.

How about this strategy:

| rex mode=sed "s/plug(\d)/plug/g" 
| spath output=pname path=powerdata{}.plug{}.plugname
| spath
| timechart max(powerdata{}.plug{}.current) as max_current,  max(powerdata{}.plug{}.voltage) as max_voltage by powerdata{}.plug{}.plugname

Need help when using your suggestion above code is working great but why do I get a result for all the plug current from Outlet_A1 - Outlet_B8 are showing the same result like 1.97 and so on. It should show the difference for each Outlet-A1 - Outlet_B8 base on the plug current. See screenshot for details.

Updated I got it to display all the plug now from at lest 1 digit or more

| rex mode=sed "s/plug(\d+)/plug/g"

By follow the splunk doc regular expression

Another thing that I found out when using the above code my result for all plug current and voltage is not correct.

Hi,

I take it back got it to work now by using your strategy above code.
Once last thing, Base on my work.jpg, I would like to show or display all Legend Label in splunk bar chart dashboard, as of now only show up to 9 items on the legend. Is there away to display all legend label?

If I performed my search like this is working

index="main"
| rex mode=sed "s/plug(\d)/plug/g"
| spath output=pname path=powerdata{}.plug{}.plugname
| spath
| timechart max(powerdata{}.plug{}.current) as max_current by powerdata{}.plug{}.plugname

alt text

but I would like to filter my search base on dropdown selection with the token as siteid=$siteid$ and location=$location$
if I want to perform my search as the below. It said no result found in dasboard.

| search siteid=$siteid$ location=$location$
| rex mode=sed "s/plug(\d)/plug/g"
| spath output=pname path=powerdata{}.plug{}.plugname
| spath
| timechart max(powerdata{}.plug{}.current) as max_current by powerdata{}.plug{}.plugname
