Hi Steven,
In the original gantt chart sample code, the label are formatted using the two format strings "{value|mmm d}" and "-{value|d}". For example, in PHP, the sample code is like:
$c->yAxis->setMultiFormat(StartOfMonthFilter(), "<*font=arialbd.ttf*>{value|mmm d}",
StartOfDayFilter(), "-{value|d}");
For the labels in your message, the month and day are in separate lines. To do this, you just need to insert a line break in the format string. In some programming languages, a line break is "\\n". You can also use the CDML tag <*br*> for a line break. For example:
{value|mmm}<*br*>{value|d}
Hope this can help.
