Column chart with Multiple chart overlay series ?

pgadhari — Thu, 02 Apr 2020 11:20:30 GMT

I have 3 columns in my search output. For e.g. date, col1, col2, col3. Date will be X-Axis
The column chart will show the bars for the value of Col1 by date and I want to do the chart overlay for col2 and col3 on this column chart. At present, I can overlay col2 series values on the chart, but not able to figure out how can I overlay third col3 on the same column chart ? Please help in this ?

For eg. attached image has the details (query output and graph I want to show ). The bars represents the avg number of hours users worked for that date, also the yellow line represents the same thing ( used appendcols with the same search to overlay the value on bars), so that it can show the trend. I want to add the third overlay ( red line), that will show the number of total users (user_count) on that particular day ?

user_count and "Avg User Session Time" should be the overlay on the bars.

Also, I am not able to sort the date properly, April values are showing first and then march values ?

Below is my query :

index=paloalto sourcetype="syslog" userid!="tem*" zone="VPN" | eval date=date_mday+" - "+date_month |stats earliest(_time) as earliest latest(_time) as latest by userid,status,date | sort date| where status="login" | eval duration=latest-earliest  | stats avg(duration) as duration dc(userid) as user_count by date| eval duration=round(duration/60/60,0) | rename date as Date duration as "Avg User Session Time (Hrs)" | appendcols [ search index=paloalto sourcetype="syslog" userid!="tem*" zone="VPN" | eval date=date_mday+" - "+date_month |stats earliest(_time) as earliest latest(_time) as latest by userid,status,date | sort date| where status="login" | eval duration=latest-earliest  | stats avg(duration) as duration by date| eval duration=round(duration/60/60,0) | rename date as Date duration as "Avg User Session Time" ]

Is it like this?

If you want User_count display in the middle of bar, you should use the trick

I am able to plot the series like the one you have done, but actually there are some issues, listed below :

The date is not showing in chronological order, it should start with 26-march, 27-march,...., 2-april
I want to display the line Avg_user_session on top of the bar and
I want to display user_count in the middle of the bar so that we identify the series properly.

How can I display the chart like the one attached ? the first image I attached in my question ? is that possible ?

I can understand that we have to multiply by 0.02, but then it is not showing the actual figures (user_count) on the chart, and this will confuse the people as it is displaying the values like 3.32, 1.5 etc. I can understand that you are trying to fit it in the scale, but that will create more confusion for the users to read the chart. Any other method is there ?

@pgadhari
If you don't display Avg_user_session , User_count can display with original value.
It can't be helped by default chart.

Yes, I thought so thats why I opened the question to check if any options available for it. But, thanks for your quick reponse and support. I will not display Avg_usesr_session and keep the chart as simple.

Also, thanks for that trick.
