VRM y-axis scaling unnecessary restriction

[PetaJoule]

and slightly off wording choice. Quite some time ago, I could not get ANY sensible
results from custom widgets, so I forgot about the feature. Having been pointed
to it again and I got immediately what I needed, I thought I give it more attention.
This is a custom widget I could live with:

However, that is only the preview. So VRM could do it. But it won’t let me:

The devs might want to replace the word “should” with “must” - or even better yet, assume the user knows what he wants and let him - see preview.

Because after VRM decides that your choice of y-axes is bad and its own is probably better, when looking at the widget in VRM, it shows these “beautiful” y-axes:

and that’s something I really don’t want to have to look at. Why did I try custom y-axes at all? Because the autoscaling does not recognize values that should be treated equally:

You wonder how a 120W PV power output could be only slightly higher than a 40W power output unless you see the widget scaled them differently.

Maybe even the option for the default scaling (most of the time it does get things right) to lock in values with other values? That way I could configure it to lock in scaling of voltages together and that of power outputs and let it do the rest. Could be fine.

It s the 42 that the issue on your y axis shoice so just use 21?
You don’t even need to use the same scaling for all data sets.
I do agree though i would like to be able to group datasets with the same scale and range.

In the same order of ideas, what one can do when one scale is with decimals and one not…

The issue is not just the 42, but also the 200. This was my attempt to give both “10 steps” on the y axis. The real underlying issue I have with the scaling is that this “window of interest”:

got mangled into what I show in the last screenshot in my OP. I would have expected and liked if the zoom didn’t rescale, nota bene all of the values with their own individual scale.

As is, zooming doesn’t really clarify such windows of interest.

Intervals means how many bars you want, not the numerical value between bars. So scaled 0 to 240 with 10 intervals will give 0, 24, 48 etc scaled 0 to 240 with 12 intervals will be 0, 20, 40 etc.

The name intervals is a little confusing.
