Dynamic x-axis

Question

My charts (v2.0.0-beta.1) are based on a timeline which may span multiple years. I am collecting millisecond timestamps which are mapped to a precision of one minute along your proposal here: https://patrykandpatrick.com/vico/wiki/cartesian-charts/value-formatting/
That works.

Now, depending on the time span of the data at hand I decide if the horizontal labels are formatted as "yyyy MMM" or "MMM dd", this works as well.
But what I really want is for this to be dynamic, based on what's on the screen. One might start with showing a year of data where "MMM dd" fits well, and as you zoom in, maybe into one particular week, I'd like to change to e.g. "dd HH:mm", down to the maximum resolution of 1 minute and "HH:mm"

What I think I need for this would be the first and last item which is shown on screen. Is there any way to retrieve these values inside a CartesianValueFormatter? Or maybe there is a better way to achieve this?

I am interested in similar behavior. In addition to wanting to change timestamp formatting, I want to be able to show in an external compose view what the current time range is for the currently visible data in the chart.
In my case we are preferring to not allow zoom, only allowing horizontal scrolling, and instead modify xStep values to affect the "density" of the data in the current view based on external buttons. The intricacies of the specifics of my implementation aside, is there a way to achieve what OP asked about? Receiving the first and last items shown on screen as the user zooms / scrolls?
