Issue on plotting Bar Graph


I am using InfluxDB + grafana 3.0

Bar graph not support for single row, it shows as point.

So same single row duplicate to 3 rows with different time_series .
Now i am getting either 3 bars or 2 bars based on group by “time interval” and zoom option, But i am not able to get single bar
Can some one help me on how to get single bar.

Sample: View and query

time_series ets unique_id usr

1490859531962600 2,441 1490859531962507 us2
1490859531964600 2,441 1490859531962507 us2
1490859531966600 2,441 1490859531962507 us2

SELECT mean(“ets”) FROM “test_results_metrics_view” WHERE “unique_id” =~ /$unique_id$/ AND $timeFilter GROUP BY time($interval), “usr” fill(null)

The bar graph shows the data that is returned from the query. In this case, the query is returning 3 rows. If I understand correctly, you want to group these three rows into one row?

  • What value have you set for the Group by time interval field? These values look very close together in time if you set the value: >10s then they should be grouped as one.

Yes, I want each usr column (us01) as one bar.

If Group by time interval field >1s , I am getting for each usr column 4 bars. so totally 24 bars
If Group by time interval field >3s , I am getting for each usr column 2 bars. so totally 12 bars

If Group by time interval field >10s i am getting single point for each usr, not single bar

Below is my query and data. Same data repeated with 4 different time_series with interval 1sec and each usr column data interval is “8s”

Please help on this


SELECT mean(“ets”) FROM “test_results_metrics_view” WHERE “unique_id” =~ /$unique_id$/ AND $timeFilter GROUP BY time($interval) “usr” fill(null)

time_series ets unique_id usr

I think what you are asking for is the x-axis Mode feature for the Graph panel. The default is to to show a graph for a time series but you can also choose to graph per serie rather than per time interval.

Here is an example:

Thank you so much . But this option is not available in Grafana 3.1.1. Which release of Grafana this option available.

As above shared link, grafana shows version 4.3.0 . should i use this version?

I think it got added in version 4.0.

I am having 4.1.1 windows, even 4.1.1 version this option not available . Any way i will download 4.3 and try this option. Thank you so much for your quick help .

I just tested version 4.1.1 and it does have that option.

Thank you so much . By using 3.1.1 version i made these graph by adding one more null “usr” row for each “usr”.

But one scenario , If I have one “usr” . So I am not getting single bar. is bar graph requires minimum 2 “usr” while using group by “usr”.

i am falling same type of problem. in my mssql server i saw that my state result is
the query is ( select count(*) , tx_state from T_ATM group by tx_state )

when i am use time series in my grafana the dashboard look like

grafana time series query is
SELECT dtt_mod = CAST(dtt_mod AS DATE)
, tx_state


WHERE $__timeFilter(dtt_mod)
GROUP BY tx_state, dtt_mod

SELECT $__time(dtt_mod)

, count(*)
, tx_state

GROUP BY dtt_mod,tx_state
ORDER BY dtt_mod ASC

i do not understand how i will get mssql server result show in grafana pie chart or histrogram or graph e.t.c
