Rounding problem with Y axis labels

[candlerb]

(Relates to #3084)

What did you do?

Collect data from apcupsd-exporter

In the console, entered apcups_time_left_seconds/60 as the metric expression to graph

What did you expect to see?

A graph with battery remaining time in minutes rather than seconds

What did you see instead? Under which circumstances?

The graph is OK but the Y axis labels are broken.

The data points are 20.5, 21, 21.5 (the raw data points are 1230, 1260, 1290)

Labels should be:

• 21.6
• 21.4
• 21.2
• 21.0
• 20.8
• 20.6
• 20.4

However the actual labels displayed are:

• 21.6
• 00000000002
• 00000000003
• 00000000004
• 00000000004
• 20.6
• 00000000002

Is this still happening with 1.7.2?

[candlerb]

I have only been using 2.0.0 train - the report was for 2.0.0 beta 2, and I am now on 2.0.0 beta 5. If the fix is in beta 5 I can try to reproduce.

[brian-brazil]

It hasn't made it to the 2.0 branches yet.

Should be fixed, please re-open otherwise.
