Request for decimal precision

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?

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.

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.

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.

@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)
