Custom grid line?

[Martin]

Hi,
I need to draw a custom grid line (to mark a border value) in my grid. Is this possible with the ASP.NET AJAX version of the Chart control? I want to do something like this: http://www.telerik.com/help/silverlight/radchart-features-annotations-custom-gridline.html

I would like my chart to look something like the attached image.

Im using version 2011.3.1115.35.


Regards,

Hi Martin,

Although the ASP RadChart does not provide a direct analogue of the custom grid line from the SL/WPF RadChart, you can achieve a similar effect using marked zones. Here is an example:

RadChart1.PlotArea.MarkedZones.Add(
    new ChartMarkedZone { ValueStartY = 10, ValueEndY = 11 } );

PlotArea MarkedZones are ranges that can be labeled and filled to highlight areas of the chart or to visually group data. The MarkedZones property is displayed by default behind the chart series. You can create any number of members for the MarkedZones collection and each marked zone is defined by a starting and ending X and Y value pairs. You can also control the labeling and appearance for each zone independently.
