Hi all

We recently have been going through a lengthy process to upgrade from VS2003 to VS2010 this included upgrading nevron charts from:

Nevron Chart for .NET Ent. Q4 2005 (N.CH.NET.40.ENT),

to

Nevron .NET Vision Pro. 2010 Vol.1 (N.DNV.NET.101.PRO

We have managed to get every thing working using Net framework 2.0. If we migrate to 4.0, we however, get hundreds of errors across all our nevron chart components.   The following is the simplest chart we have in our package I have double ## those lines that currently have errors

Any help appreciated Thanks

Hi Warwick,

You need to use the scale configurators in newer versons of the control - for example:

NNumericScaleConfigurator scaleY = new NNumericScaleConfigurator();
scaleY.MajorGridStyle.LineStyle.Pattern = LinePattern.Dot;
scaleY.Title.Text = "Rate of Change";
scaleY.MajorGridStyle.SetShowAtWall(ChartWallType.Back, true);
chart.Axis(StandardAxis.PrimaryY).ScaleConfigurator = scaleY;

changes the title and major grid style properties.
