DateTimeNumericAxis: Jan month is always displayed

Hello,

Thank you for the quick reply. I tried the suggestion but still no luck, I also added a prefix value which does not seem to show up. Any ideas on what I could be doing wrong?

Hi Sergio,

This behaviour is by-design, where you have a time-based axis with DateTimeNumericAxis, it uses the SmartDateLabelProvider type, which shows the date on day transitions and month name on month transitions. For example:

• Given these labels: 23:50, 23:55, 00:00, 00:05, 00:10, the middle label (00:00) will always show the date/day transition, such as Jan 1 (or whatever the date is)
• Given these labels as days of the month: 29, 30, 1, 2, 3 , the middle label (1) will always show the month name transition, such as Jan or Feb (or whatever the month is)

How to disable it

If you want a pure time axis with DateTimeNumericAxis then set the LabeProvider property as follows:

const xAxis = new DateTimeNumericAxis(wasmContext, { 
   labelProvider: new DateLabelProvider({ 
      labelFormat: ENumericFormat.Date_HHMM
      cursorLabelFormat: ENumericFormat.Date_HHMM 
   }) 
});

This will give you fixed HH:MM format without the transitions on day/month, but it will no longer be dynamic as well.
