I've been trying to implement some drag-drop functionality for my charting application. I've used the following code in the MouseMove event for the control to determine the location of the mouse:
e = chtData.HitTest(e.AbsoluteLocation.X, e.AbsoluteLocation.Y, True)
Dim objTarget as object = e.HitType()
Unfortunately in the DragDrop event handler the ChartFX.WinForms.HitTestEventArgs parameter is not provided. The DragEventargs property available from the DragDrop Event does not provide 'AbsoluteLocation' functionality.
In the DragDrop event I need to identify if the user is trying to drop the data/object onto an Axis, into a Pane, etc. For some reason I am having a tough time figuring out how to duplicate the logic from the MouseMove event in the DragDrop event. Any help would be most appreciated.

Did you find a resolution to this issue? I just did an update and I am having the same problem with my WinForm project in VS2010

I have a charting application that is retrieving date/time based data from a database which is working well. I evaluate the data and if any gaps in time exist in the data I add a coloured Axis Section to the X-Axis to highlight this to the end user. These AxisSections also appear in the LegendBox.
There are times when multiple data gaps exist for a chart, therefore multiple Sections are displayed. I would like only one entry in the Legend Box to indicate what the coloured sections represent (i.e. Missing Data), however I have been unable to achieve this. How can I display one Legend Box entry for the multiple Axis Sections, and is it possible to highlight all Sections when the user hovers over the single LegendBox entry?
Thanks in advance.
Retrieving Compacted Data
in Windows Forms
Posted
I have a winform application that leverages the Compating funcitonality of the ChartFx control and it works great.
I am trying to implement an 'Export to Excel' option that would enable the user to export the data as it appears on the chart. I can easily use the raw data being used in the chart for this, however I would rather export the data that the chart is based on (when compacting is being used). Is there anyway of accessing the compacted data ? I need to get access to both the Series Data and X-Axis (compacted date)
Thanks in advance for any assistance
