Cognite Charts: Feature to mark Milestones or add comments to ChartGathering Interest

Following up from a separate thread (Cognite Charts: y-axis Spacing and Labeling), adding the capability to place timestamped milestones (e.g. when an event started, when a remediation test started, etc) would add value.  I sometimes need to display a time series only to mark an event (e.g. when a valve was opened, when a specific chemical injection start/ends, etc), and this leads to many times series being displayed at once (see example below). If milestones could be marked on the chart, that would be really useful. Maybe it could be added as some sort of custom time series (similar to how to “Add Calculation”) fixed to a specific timestamp and could appear as a vertical line with some marker at the top - this is just me thinking out loud.Thanks,Richard

Charts: Shift Time Series function Limitations on "Displayed" Data

In Charts, we have been using the “Shift Time Series” function (for creating a new Calculation time series) to assess data more effectively, but have now noticed a limitation where the calculation is limited to the data from the source time series already displayed.  If you look at the first image below (just a 10-min shift), you can see in the green calculation that there is a gap on the left where the calculation doesn’t exist due to the source data being “off the page”.  If we go to a more extreme scenario (2nd image below), now of the data shows since we are attempting a 2+ day shift in a time series.  Is there a solution where this limitation can be removed?  For our scenario specifically, we are looking closely at (and comparing) three separate incidents that lasted about 1 minute each, but were spread out over the course of a week, so we are super zoomed in to look at the behavior signatures.  Thanks for the input!Kind regards,Richard10-minute shift​​​​​ Multiple-day shift

Cognite Charts: y-axis Spacing and LabelingGathering Interest

When looking at many time series (8+), the y-axis scales take up a lot of space on your screen horizontally, and adding more time series to the display continues reducing the x-axis space on the chart itself.  Having the ability to compress the horizontal space occupied by the y-axis scales would be helpful, especially since there seems to be a lot of white space available to compress into.  We have run into this challenge during real-time troubleshooting, and it becomes especially challenging when working off a smaller screen (e.g. using your laptop screen in a conference room). As you can see from the first image below, the white space around the y-axis scales/labels appears significant.  The 2nd image below is a more aggressive shot of the same Chart.Additionally, a feature where hovering your mouse above a particular y-axis would reveal the name of the time series that y-axis applies to would also be helpful when the y-axis units are not merged.  This is really more useful when loo
