Let me go straight to the point, as I am ashame of even asking this but, how do I bin values in vega-lite to make a histogram ?
I did look at the examples flourishing on vega and vega-lite’ pages and at the documentation, using basic tables or the car dataset. I can reproduce those examples. The difference is that in my case I have (to simplify) ids associated with timestamps (unit s). In d3 or python, I can easily do a value_counts() on any round value of the timestamps and display the number of ids in that time interval, but how do I do that in vega lite ?
For example how do I bin the ids per hours to show the total number of ids hour per hour ?
