Time tick issue on x-axis

Specific Domains Visualization

Here is the VegaLite.jl way:

using VegaLite, DataFrames, Dates

n = 1000

 df = DataFrame(time = rand(DateTime(2018,1,1):Hour(1):DateTime(2019,1,1), n))

df |> @vlplot(:bar, x="yearmonthdate(time):o", y="count()")

Note how the only difference to the previous example is that I now use the yearmonthdate time unit instead of the hours time unit. You can see all time units that are supported by vega-lite here.

You’d probably want to adjust the width of the bars in this example, otherwise the plot gets a bit wide :slight_smile:
