Add axis range option: max

Currently axis ranges can be set to automatic or manual. Issue: What I observe is that the axis range is determined on the >visual< bars/dots/etc. However, this is confusing as scrolling causes the axis to dynamically change. Proposal: Add a third option which either sets the scale to all data points visible and not. Alternatively, but less user friendly in some use cases, allow PQL in the manual ranges (MIN/MAX() would need to be added by the user manually and in sync with the displayed KPIs so not that user friendly.
