[Feature]: Provide a config option to disable warning- and critical- timeseries by default

[domme0711]

Describe the feature request

Most of our metrics have three timeseries: value, warning and critical

If you have very small values (far away from warning/critical), the y-axis is scaled to an unflattering size and the value graph appears as a flat bottom line.

For this reason it would be nice to have the warning- and critical- series disabled by default (just hidden, not completly removed). This should be configurable since not everybody may like that behaviour.

Hi, yeah we've been thinking about this. The idea behind current behavior was, so that users have more information (i.e. all three timeseries) without having to click somewhere.

But yes, as you said, the value series often times is not visible.

I achieved the desired behaviour by applying this patch to module.js:

+                            show = false;
                         }

                         u.addSeries({

But it would be nice to have this as an option.

I don't have a clear idea on how to implement this yet and how the config should look like. Once I do, or someone has an idea, this will be implemented.
