  Hi all,
  
  The new version of RadChart (v4.0) introduces better performance and expands its functionality over new areas. Additionally, many new features were implemented to reflect the numerous client requests.
  
  However, this transition required a significant modification of the server API of the control. To make the migration process from the previous version of RadChart as easy as possible, we have prepared a document holding all API changes made for v4. You will find it attached to this forum post.
  
  Best regards,
  The Telerik team

  Hello,
  One question about the changes in the API.
  What happened to Telerik.Charting.ChartPointMark enumeration that was available in the previous version of RadChart (v3.1.2.0)?
  Information regarding how to migrate ChartPointMark is missing in your attached document and in the installed/online control's help.
  
  Would you please provide instructions on how ChartPointMark should be updated? For example if a method uses a parameter of type ChartPointMark, what should the type be now so that one can access the kind of point mark ( rectangle, cross, diamond, etc) ?
  
  Environment:
  - ASP.NET 2.0
  - Visual Studio 2005
  - VB.NET
  - RadControls Q2 2007
  
  Thanks in advance.
  Cécile

  Hello cecile,
  
  Thank you for your feedback. The ChartPointMark enumeration has been expanded. Here is how to set up point marks with the new API:
  
          RadChart1.Series[0].Appearance.PointMark.Visible = true;
          RadChart1.Series[0].Appearance.PointMark.FillStyle.FillType = FillType.Solid;
          RadChart1.Series[0].Appearance.PointMark.FillStyle.MainColor = Color.Red;
          RadChart1.Series[0].Appearance.PointMark.Figure = DefaultFigures.Diamond;
  
  or in the ASPX
  
  <radC:ChartSeries type="Line">
      <Appearance>
           <PointMark Visible="true" FillStyle-FillType="Solid" FillStyle-MainColor="red" />
      </Appearance>
      <Items>
      ....
      </Items>
  </radC:ChartSeries>
  
  We will update the documentation as per your request. Your points have been updated.

  Dear telerik,
  
  Regarding the documentation, is there a substitute now for the old legend.location property (v3)? In the documentation file, the equilivant column for V4 is blank on this one. I need to know if this has been updated.
  
  Thanks,
  Andrew

  and along the same lines, the v4 equivalent of the v3 charttitle.location?

  I'm also changing this v3 property:
  
  series.labelAppearance.TextFont
  
  to series.appearance.LabelAppearance.
  
  at this point, I'm needing two properties as per the documentation:
  .textblock.appearance.textproperties.color
  .textblock.appearance.textproperties.font
  
  but .textblock is not in the properties box menu after .labelappearance. In alphabetical order is should be after showLabelConnector and before ToString, but it's not.
  
  Is something missing here?
  
  Thanks,
  Andrew

  Hi Andrew,
  
  Onto your questions:
  

  • RadChart.Legend.Location is now RadChart.Legend.Appearance.Location
  • Unfortunately, this property is no longer available for ChartTitle. Please, use RadChart.ChartTitle.Appearance.Position to customize the title position
  • [Series].LabelAppearance.TextFont is now [Series].Appearance.TextAppearance.TextProperties.Font

  I hope this helps.
