XY table perspective seconds formatted yAxes


I’m really new to ignition and I have some questions. I start with a simple one:

In perspective I’ve an XY chart and on the Y axis I’ve seconds. I would like to show them as HH:mm:ss and not as a simple integer, but in the “format” hints I see nothing that can help me…

I tried writing somethings in the “format” field, but with no luck.
What syntax can I use in that field to convert the seconds, so an integer, in to HH:mm:ss format?

I “just” need to calculate toInt(value/3600) + toInt( (value%3600)/60 ) + toInt( value%60 ) , but sincerely I don’t know how!

Could you help me?
