Custom gridlines on chart

[Oner]

Hello every one, I have a problem with axis gridlines. In my project I need to draw custom gridlines on the chart. On the chart I have to draw those gridlines that I calculated. I tried ArrayList, List, Array for each lines but I could not succeeded. Each line calculated simultaneusly.

Hello Oner,

Currently the RadChart for WinForms doesn't support custom grid lines. This feature is available in our WPF and Silverlight RadChart. You can see it in action in our demo here.
I hope this information helps.

Hi Yavor

I need your help on this matter:
For current WPF project I must create a report with an embedded Chart which must display horizontal gridlines (corresponding to Y axis) for certain values (not major or minor gridlines!). Please see attached file.

Short explanations: on X axis: time, on Y axis: weight (kg)

After one working day I couldn't find any solution.
Any help will be appreciated (an example would be great).

Thanks a lot!!
Dan

Hi Dan,

You can use RadChart custom GridLine functionality which allows you to display grid lines (both horizontal and vertical) on any value you want. Here is a small example:

<telerik:RadChart Name="radChart">
    <telerik:RadChart.DefaultView>
        <telerik:ChartDefaultView>
            <telerik:ChartDefaultView.ChartArea>
                <telerik:ChartArea>
                    <telerik:ChartArea.Annotations>
                        <telerik:CustomGridLine YIntercept="150"
                                    Stroke="Red"
                                     StrokeThickness="2" />
                    </telerik:ChartArea.Annotations>
                </telerik:ChartArea>
            </telerik:ChartDefaultView.ChartArea>
        </telerik:ChartDefaultView>
    </telerik:RadChart.DefaultView>
    ...
</telerik:RadChart>

You can find more information on custom GridLines in our online help system here.

If you have any other questions about RadChart for WPF please ask them in the proper category. This way other people that have similar problems can help you too.

All the best,
