Suggestion of DC charge details (interval and chart)

1. Can we have a shorter data interval (like 15s) when DC charging? It losses detail for making charge curves with a 1-minute interval because DC charging is quite fast.

2. The chart of Battery Level, Charger Voltage, ...etc in Charge Details page is like 15:1 in proportion. Can we have a 4:3 or 3:2 chart which is more readable? I can just show the chart to others with an easy screenshot. Thanks.
