User (Legacy) Posted November 20, 2003 Report Share Posted November 20, 2003 Hi, when I display a series with N values using the gallery "Area" and catch the RButtonDown event from ChartFX, the argument nPoint will only assume values 0 to N-2, but never N-1. How is it possible to catch the event for the last value in the series? Best regards, Thorsten Blawatt Link to comment Share on other sites More sharing options...
Software FX Posted November 20, 2003 Report Share Posted November 20, 2003 An are chart can only be hit BETWEEN points, we give you the lower point always. What exactly are you looking for ? -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
User (Legacy) Posted November 21, 2003 Author Report Share Posted November 21, 2003 Hi, when the user clicks on a bar / value I want to show my own context menu. How would I do this when the "area" gallery is chosen? Best regards, Thorsten Blawatt Link to comment Share on other sites More sharing options...
Software FX Posted November 21, 2003 Report Share Posted November 21, 2003 Same way. I don't know what the problem is. A BAR has a width and there is ONE bar for each point. In an Area chart in the other hand, a point has no physical size, what is drawn is a CONNECTING area between him and the next point. Therefore in an area chart, you can not click in ONE point, you always click BEWEEN two points. This is the nature of this chart type. I do not understand how Customizing Context menus is related to the first question. Can you please explain. -- FP Software FX, Inc. Link to comment Share on other sites More sharing options...
User (Legacy) Posted December 1, 2003 Author Report Share Posted December 1, 2003 In our application, each point corresponds to an object containing some more information than just the value itself. What we are trying to do is show a menu when the user right-clicks on a point giving him the chance to perform operations on the object associated with the respective point. In an area chart, however, this doesn't seem to be possible for the last point in a series because of the implementation you described. So it doesn't seem possible for us to do what we want using an area chart. We'd just like to know if there's any other way we can go or if we just should refrain from using area charts.

Software FX Posted December 1, 2003 Report Share Posted December 1, 2003 What do you suggest ? You can implement pretty much anything you want it is basically up to you. If you want the right-click to act on the point to the right you can do so, simply add 1 to the point index passed to you. This of course will make it impossible to click the first point. In other words the implementation can be anything, the important thing here is: How do YOU want your users to select a point ? given all the characteristics of the Area chart I explained before. This is not a limitation on Chart FX, this is the nature of an Area chart. You need to decide what do you want to do. -- FP Software FX, Inc.
