Thanks Ehsan, The most essential part for these issues is the ability to aggregate data (or named grouping/binning), which is scheduled in v5.4.
What you mentioned as "stacking" doesn't seem to behave like current "stacking" [1] with Apache ECharts where each stacking element belongs to different series and in most cases have different colors. As for the time series, if data should be grouped into monthly, each month should have only one bar with the sum of the data within the month, rather than stacking bars each of which represents a single data. If you have different ideas about this, please let me know and let's see what we can provide for most reasonable situations.
