 TeeChart Pro Activex Control v5 
 v5.0.5.0 Release notes:
=====================================

For information about differences and use of 
TeeChart Pro ActiveX v5 with respect to
TeeChart Pro ActiveX v4 please refer to the 
'Upgrading from TeeChart v4.doc' document 
accessible via the TeeChart Program Manager 
group.

===========================================

Changes for this release:
-------------------------

Bugs resolved:

1. ISeries.DataSource now returns multiple 
datasources when these datasources are ISeries.

2. Attaching an exported TChart to an email 
and then closing it without specifying a recipient 
caused an error. This has now been fixed.

3. ISeries.DeleteRange now correctly returns 
ISeries.FirstValueIndex and LastValueIndex.

4. Omission in previous releases, ColorLine 
Tool Draw3D and DrawBehind enable you to 
change how the ColorLine is drawn at runtime.


New features:

1. The OnNearestToolChange Event is fired every 
time the NearestTool moves from one Series point
to another. 

2. The INearestTool.Point property returns the 
ValueIndex of the new highlighted nearest point.

3. You can now fully customize all BoxPlotSeries
parameters by setting UseCustomValues property to 
True and passing your values to Quartile, 
InnerFence OuterFence and AdjacentPoint properties.

4. You can now draw a 2D polygon onto the TeeChart
Canvas at a specified Z Position.

5. Area Series now support the IGradient interface
allowing gradients to be painted on them.

6. FastLine Series has two new features
a. The ability to draw in "staired" and "inverted 
staired" mode.
b. The Vertical Axis associated with a FastLineSeries 
can be scaled automatically or manually.


Changes to note:

1. VC++ developers should note that the location
   of TeeShapePanel's Bevel has been moved to
   TeeCustomShape.

Previous Changes 
(from release v5.0.3 but still noteworthy)

1. Developers upgrading VC++ projects from projects
   created prior to TeeChart v5.0.3 should note 
   that the Series property has been deprecated to 
   comply with an import restriction to Microsoft's 
   Visual Studio .NET.
   .Net fails to import indexed properties that 
   reside at the root level of an ActiveX Control.
   The property has been replaced by a method of
   the same name. The old Series property has been
   renamed to aSeries but retains its DispId to 
   support existing, non-changed code and already
   compiled applications. When upgrading VC++ 
   classes to the latest version it should suffice
   in all standard cases to change calls of:

     Get_Series

     to
 
     Series 

2. Internet Explorer stopped supporting TeeChart's
   IPersistStream content save from IE v5.5sp2 
   onwards ! TeeChart's persist technique now 
   changed to: first choice IPropertyBag, second 
   choice IPersistStream (used by .NET for example). 
   The changes to TeeChart's persist technique 
   should be transparent and should not cause any 
   inconvenience though you may note the difference 
   on updated Frontpage saved web pages where old
   data content will remain and can be removed 
   manually. The new save format in TeeChart on an 
   HTML page will take the format: 
    
     <param name="Base64" value="..some content..">


===========================================
Key known unresolved issues:

- ChartEditorPanel not supported in MS 
  VC++ applications due to incorrect 
  behaviour of Editor buttons
- Right Axis Arrows click area not located 
  correctly on 3D Charts
- StopMouse not working correctly in
  DBlClick event
- Datasets set via the Chart Editor and requiring
  password access need the 'save password' option
  to be selected in the ADO dialogue. This is not
  a requirement when setting up an ADO connection
  via code.
- Dragdrop events not functioning in .NET.
- Only one TeeChart AX event is triggered, per 
  page, for a WebForm in ASP.Net.
