  1. 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

  2. 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.

  3. 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.
