Change mininum and maximum percentage for graphs in dashboards

[faguayot]

Describe the bug
Define the minimum and maximum in the percentage graphs since we can't have a right vision of the use of any value due to we are not painting the minimum to 0% and the maxixum which should be 100% in most of cases.

Environment
Provide accurate information about the environment to help us reproduce the issue.

• Harvest version: harvest version 23.02.0-1 (commit 627311a) (build date 2023-02-21T08:32:43-0500) linux/amd64
• OS: Red Hat Enterprise Linux release 8.4 (Ootpa)
• Install method: rhel
• ONTAP Version: 9.7 and 9.10.1

Expected behavior

Actual behavior

Additional context
It is recomment to review all dashboards, since I have seen the same situation in differents.

@Hardikl Could you check this.

Thanks @faguayot!

The advantage of the current behavior is small % differences are more obvious. Extending the range from 0 to 1 "flattens" some values and makes it harder to spot minor changes. Of course, that advantage can also be considered a con. I agree that the defaults should probably be fixed between 0 and 1. We'll investigate and get back to you.

Soft min and max may be a way to improve this, although for most of our percent panels a hard min/max will typically work fine too.

Soft min and soft max settings can prevent blips from turning into mountains when the data is mostly flat, and hard min or max derived from standard min and max field options can prevent intermittent spikes from flattening useful detail by clipping the spikes past a specific point.

Example

@cgrinds Thanks for you quick answer. I understand what you say about small % differences, and it makes sense. I guess depending on the situation could help use the minimum 0 and maximum 100 (or 1 depending on the scale) or not. When I look for something

• First I look for a long period of time and check if there is any varition of the curve even mininum.
• Second I zoom in the specific time where I've found that variation to check if there is an important change or not.

hi @faguayot if you want to try these out before the next release, you can grab the latest nightly build.
