                                  • Hi.
                                    At runtime, I created a new serie in a simple line chart with ValueScaleType property = DateTime. My aim it to show in a tooltip the value with "hh:mm" format . For this I used the following C# code:
                                     
                                    lcls_NewSerie.Label.PointOptions.ValueDateTimeOptions.Format = DateTimeFormat.Custom;

                                    lcls_NewSerie.Label.PointOptions.ValueDateTimeOptions.FormatString = "hh:mm";

                                    Rather than showing the value with hh:mm format, show only my default date ("01-01-1980").
                                    What ́s wrong with these lines of code?

                                    Thanks in advance.

                                I have tried to reproduce the problem you described, but failed. Attached is a small sample project that seems to work fine at our end.
                                Could you please provide me with step-by-step instructions on how to reproduce your problem and I will try to find an acceptable solution for you.

                                  Hi.
                                  My sample project with step-by-step instructions you asked is attached .
                                  Thank you.

                                  Thank you for the clarification. The Series.Label.PointOptions property is meant for formatting Series Labels. In the provided sample project, the Crosshair Label is shown. To customize this label format, use the SeriesBase.CrosshairLabelPattern property. I have modified the sample project to illustrate this approach. You can find it in the attachment.

                                  Hi.
                                  Sorry to bother you again... but first of all, thank your much for all support.

                                  Like you very well suggested, I used the SeriesBase.CrosshairLabelPattern property.
                                  It works fine for a a line serie. For a SideBySideRangeBar serie, otherwise, I can't used {V:HH:mm} pattern, because the serie has, as use know 2 values.

                                  You can use {V1} and {V2} placeholders to set the format for range bar labels. I have modified the sample project to illustrate this approach. You can find it in the attachment.
