Hello Zsolt,

even if you won't read this after 2 years, for other ones with a similar issue...Using the DateTimeAxis as x-axis, you can directly assign a string format to it, so you won't need your property 'LabelOnX'. Then it's just a common scenario.


Even if you have to use both properties, using two x-axis(DateTimeAxis and CategoryAxis) could be a workaround(not very nice I admit). Then one axis has to overlay the other one.
