 adding 'date' to {value} in yAxis using setLabelFormat |

Hi Peter,
using PHP for my chart, {value} is the offset from a base date. For example,
if the base date were '2021-6-15' , then the date '2021-6-25' would have {value}=10.
And {value} =15 for the date '2021-6-30'. etc.
I'd like to show the actual date in the yAxis instead of its offset.
I've tried converting everything to seconds, adding them, and then converting back.
$c->yAxis->setLabelFormat ("{= getChartYMD( ({value}*24*60*60 +ChartTime(2021,6,15) )) }");
That didn't work. I expect it failed because you can't call functions from inside of
setLabelFormat??
Any ideas?
Thanks!

Hi Richard,
I would try:
$c->yAxis->setLabelFormat("{={value}*86400+" . chartTime(2021,6,15) . "|yyyy-mm-dd}");
Hope this can help.
