Thank you for writing back.
The issue with only one label visible is actually caused by a caching mechanism inside the chart axis. The problem is that the axis caches label elements and uses their content as key for the cache storage. The issue is only observed when using labels with milliseconds and is caused because the axis calls the ToString method of the DateTime object that is the category of each data point. This results in a string that does not contain the milliseconds part and therefore for all labels the same element is returned and drawn in the chart area. I have logged this issue in our feedback portal. You can track the progress of the issue, add your vote or comment to it and subscribe for status change alerts on the following link - Feedback item.
Unfortunately, due to the nature of the issue, I am not able to provide you with a workaround.
I have also updated your Telerik Points
for bringing this issue to our attention.
As to the categories being used in a DateTimeContinuousAxis
. The mechanism for generating labels is pretty much the same for DateTimeCategorical
and continuous axes. The difference is in the layout of these labels. So strictly speaking these are not categories but formally they are pretty similar.
I hope this will be useful. If you have further questions, I would be glad to assist.
