Doc Type: Bug Fix
Doc Text:
Previously, when there was no/minimal data, the default value was set for the Y-axis on graphs between the range of -1 to 1. As a result, when there was no/minimal data in the *Developer Console*, the monitoring charts or graphs, for example, CPU consumption, memory, usage, and bandwidth, show between the range of -1 to 1. However, these values could never go below 0. With this fix, the default value is updated for the Y-axis between the range of 0 to 1. As a result, the monitoring charts or graphs show between the range of 0 to 1 and none of the values show below 0. (link:https://bugzilla.redhat.com/show_bug.cgi?id=1904106[*BZ#1904106*])

Description Tim deBoer 2020-12-03 15:18:16 UTC
Description of problem:
In the dev console when there is minimal/no data, most of the monitoring charts (CPU/memory use, bandwidth, etc) show a range of -1 to 1. None of these values can ever go below zero so the default looks very odd, and changes/jumps quite a bit the moment there is any data.

How reproducible:
Always.

Steps to Reproduce:
Look at a pod that hasn't had any activity or scale one to zero.

Actual results:
Default charts show range of -1 to 1 with no units.
When there is data the graph changes completely and adds units.

Expected results:
Option 1 - The bottom end of the range should be 0 for all of these charts, and ideally have unit labels (e.g. memory could be 0M to 1M)
Option 2 - If there is no data, show 'no data' instead of showing a chart.

Moving to 4.8 as we likely can't get this into 4.7 due to bandwidth.

Updated the doc text field.

Verified on 4.12.0-0.ci-2022-10-09-233202

could see the default value for the Y-axis is [0,1].
