Apex chart, can the date be removed?

Configuration Frontend

I have this chart:

image770×511 23.3 KB

And the new day prints the date in the chart, is there any way I can remove this so that I only get the hours?

I already have

    xaxis:
      labels:
        datetimeFormatter:
          hour: HH

which does give me the hours in two digits instead of hh:mm but it does not seem to do the trick with the date
