Now I have done through mvvm:
XyDataSeries<double, double> + <s:NumericAxis/>
XyDataSeries<DateTime, double> + <s:DateTimeAxis/>
That is to change the format title of axis-X I have to reload the data.
When this database is x:long y:double
Question.
If the input for the axis-X long, can somehow format the title? For example long/100 or convert long in DateTime?
That is, the output format set after loading data.

Ok, I still don’t understand 100% what you are asking, but I think you wish to know:
- How to format the XAxis labels to show either DateTime or Numeric values when X-Data is type Int64
Is this correct?
If so, please take a look at our article on Specifying Text Labels with LabelProvider.
I suggest creating a LabelFormatter than can output both DateTime or Numeric values, e.g. try this:
public class DateOrNumericLabelProvider : LabelProviderBase { public bool DisplayAsDateTime { get; set; } public override string FormatLabel(IComparable dataValue) { if (DisplayAsDateTime) { // Format axis label as a DateTime return new DateTime((long) dataValue).ToString("dd-MMM-yyyy"); } // Format axis label as a numeric value return ((long) dataValue).ToString(); } public override string FormatCursorLabel(IComparable dataValue) { // TODO: You can do a cursor-specific implementation here return FormatLabel(dataValue); } }
Then apply to the XAxis.LabelProvider and set the DisplayAsDateTime property to True or False.
Best regards,
Andrew
