    Hi, 

    When i have a great range of datetime values (1000+ itens in the AxisX), the auto range doesn't work, whereas i defining the autorange property with true. 

    Another problem consists in the label values on the axisX, that's defined as 30/12/1899 when the data series gets a big value.

    Take a look at the attached screen. How can i send one sample application that shows the problem?


    Note: The problem only happens when i define the DapaPointMember property to "XCategory". With "XValue" option, it's all ok, but i need to work with XCategory value, because the chart handles other curves configurations.

    Thanks for your attention!

    Hello Bruno,

    You cannot use XValue and XCategory simultaneously.When using XValue items will be placed at the corresponding position along the X axis, XValue should be double or DateTime. Using XCategory forces the chart to arrange the items in a sequential manner and to create a category for each item. With a large amount of data using XValue is the appropriate choice.

    You can send us a sample application, which demonstrates the issues you've encountered, by opening a support ticket and attaching it. This way we would be able to assist you further.
