Request for decimal precision

[ghost]

Hi,
The new way that Grafana automatically tries to put decimal points in or round small numbers if necessary is messing up a lot of my graphs. I would like the ability to choose a "X.XX" (or X number of decimal places) number format so that it doesn't keep rounding my values.

Thanks

Do you have any examples where the auto decimal precision is causing problems?

[ghost]

Hello,
Here, we have three very similar graphs working from percentage functions. They only switch to having decimal places when the range is very tiny, like in the top one. The values are always floats but get rounded if the range of the graph is more than about 6, I think.

Note that the mouse hover values have decimal points if the legend ones do.

[torkelo]

yes, the decimal precision is based on how large the distance is between two labels on the y axis.

The cut-off point is far too low I think. Version 1.8 showed the percentages fine. An option would be good.

Same issue with temperatures, I would like to see at least one decimal.

On the other hand, the pressure (Pression) in hPa should be displayed without decimal : 1033 instead of 1.03300 K.

Hi,

Am also having this issue, some graphs show decimal points while it rounds off some to integer values, the previous version works well with the decimal numbers...

Any help on this?

I downgraded to 1.8.1 and it does not have that problem.

[torkelo]

The previous version did not work so well in many other cases (as it was hard coded to only 2 decimals in all scenarios). I will try to solve this when I have time. The decimal precision (especially when scaling units, ns -> ms -> s -> min, or K -> Mil -> Bil) is so complex that it is tricky to get all scenarios right.

Ok...No prob then..

I appreciate the good work. Many thanks

it's basically last issue keeping us from deploying Grafana at production.

[torkelo]

@henkye well if you put it like that I guess I just have to fix it, which I just did :)

Both singlestat and graph panel now have a decimal override option, works with all unit formats.

Only fixed in develop branch (Grafana 2.0)

That's awesome, thank you.

@torkelo great, looks like I'm VIP :-)
Thank you and happy graphing! We at stable.cz appreciate your work.

Where is this option now? I cannot find the graph precision setting..

[rebeccathedev]

Seconding @ireun's question. I'm using 3.3.1 and I don't see this option anywhere on graph settings.

[phemmer]

Thirding the question. I'm on 3.1.1 (a lowly peasant and don't have time travel capabilities to get 3.3.1 :-P)

Edit: Found it (stumbled across it adjusting other settings)

[ireun]

Quadding the question. I also found it a while ago, anyway, thank You. ;)

[rebeccathedev]

Sorry, fat fingered the version number. It's 3.1.1.

For me that works on the legend but not on the axis, though. At least not when I zoom

[ireun]

@peckrob How do you check which version of grafana are you using? Honestly, I have no idea which one am I using.

And yes, it only sets the precision of the legend, not te axis. Though it shows the graph with as high precision as possible, if that's necessary. I'm using grafana to show data from my weather sensors, and I'm using moving_avarage() function of InfluxDB, to smooth the graph and add values between the readings..

Edit:

Unpacking grafana (3.1.1-1470047149) over (3.1.0-1468321182) ...

Got it. ;)

[Corbyn]

It would be very helpful to have the decimal precision override option also for the y axis! If the value stays constant over a long time (like it is often with disk usage) Grafana always puts in as many decimals as possible and that messes up the graphs...

[sunface]

met the same bug with Corbyn, y axis precision need to be overrided too!

[rende2005]

Same issue here for the unexpected y-axis lable display. Eager to see the fix/enhancement. Thanks!

[torkelo]

should be fixed/improved in v4.0

[tomekit]

Facing similar issue, +1 bump :)

Hello!
Unfortunately looks like not fixed for y-axis label display in v4.1.1

grafana-server -v
Version 4.1.1 (commit: v4.1.1)

from 4.1.1-1484211277 deb package.

Avg, max in legend looks ok after set "Decimals".
But y-axis with "Decimals" 2 in legend looks -

Hello All,
@torkelo

I am using Prometheus 2.3.2 and Grafana 5.2.2 Versions, I have created ActiveMQ Message Alert Rules, I am getting Alerts I decimals(value=1.048) when I crossed checked with Grafana panel(value=2) and in Prometheus, it's in Integer(Value=2). It's a message so it won't be in Decimal.
Can anyone tell me please how to figure it out this problem?

Its Imp to solve :(

thanks

Folks under Axes section (in Unit) you can select the value whichever you want, even i had same issue, after checking this helped me:
