Subject: mgr/dashboard: Round off y-axis value of area chart
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=a6012c3954830f4b60ef49218d40d4e8ed3bd14c;p=ceph.git

mgr/dashboard: Round off y-axis value of area chart

- by default y-axos set to 1 for all
- the value round off for area chart is seperated from y-axis ticks
- also fixes a bug where all IOPS y-ticks being repeated 1,1,0,0

The following values are set for now:

IOPS: valueDecimals=0, axisDecimals=1
Latency: valueDecimals=2, axisDecimals=1
Throughput: valueDecimals=2, axisDecimals=1
Consumption: valueDecimals=2, axisDecimals=1

Fixes https://tracker.ceph.com/issues/76191
