                                  • We now have 4 new dependency properties for crosshairs on the chart control but I can't find any documentation on it (To be supplied).


                                    I can figure CrosshairEnabled and CrosshairLabelVisibility but I want more information on CrosshairLabelTemplate and in particular CrosshairLabelPattern.


                                    Thanks in advance,

                                    Sébastien Chandonnet

                                Hello Sebastien,

                                We apologize that you didn't find necessary information in our help files. Would you please clarify where you found "To be supplied" topics, so that we can reproduce this problem?

                                In any case, the latest version of our help files is always available on our website at http://documentation.devexpress.com. In particular, here you can find information about the crosshair-related properties:

                                Currently these topics provide only basic information about the properties, but we are planning to update them very soon.

                                  In fact the "to be supplied" is in the "inline documentation/XML Documentation" of the library. The documentation you got when using the intellisense directly in the code.

                                  Like you said the information is too basic. We need more info like how to use the DataContext when designing the template and what are the "renderers" ({A}, {V}) when specifying a pattern etc ...

                                  Anyway, thanks for the links, my previous search on your online documentation returned nothing. Maybe I did a mistake.

                                  Hello Sebastien,

                                  Thank you for your clarification, I see the problem with the inline documentation in the VS code editor. We apologize for this issue and will fix it with the next minor update to our products.

                                  As for the CrosshairLabelPattern and CrosshairLabelTemplate properties, we will prepare examples of their usage soon and will update this thread. Please bear with us.

                                  Best regards, Alan.

                                  The following strings can be used in the CrosshairLabelPattern property:
                                  "{A}" - argument;
                                  "{V}" - value;
                                  "{VP}" - percent value (for Pie series)
                                  "{S}" - series name;
                                  "{G}" - name of a stacked group;
                                  "{W}" - weight (for Bubble series)
                                  "{V1}" - value1 (for Range series)
                                  "{V2}" - value2 (for Range series)
                                  "{HV}" - high value (for Financial series)
                                  "{LV}" - low value (for Financial series)
                                  "{OV}" - open value (for Financial series)
                                  "{CV}" - close value (for Financial series)

                                  Currently we are working on an example to demonstrate how to use the CrosshairLabelTemplate property. After we publish it, we will update this thread.
