I have tried to implement a line chart along with Notes,. but the problem arises when 2 notes are very close to each other they overlap and are not readable. I tried adding margin but could not achieve a good result even with rotation it looks very absurd. 

I am trying to figure out a way where I can display the notes in one series alternatively top or down. But I can't find anything. I only got an option to display notes top or down per series. Need help with this?

Or if any other way I can achieve it with a readable format

hi all, 

 

how can i show text just above the line series in a RadCartesianChart?

 

                                <telerik:LineSeries ItemsSource="{Binding CurrentChartData.PassingScoreLine}"
                                                    ValueBinding="Score"
                                                    CategoryBinding="XCategory"
                                                    Stroke="Blue"
                                                    Foreground="Blue">

                                </telerik:LineSeries>

 

thanks.

Hallo!

Is it possible to bind a SmartLabel to DataPoint.IsSelected property!

I have a ChartSeries with more than 10.000 DataPoints. When i specify a DataPointTemplate, the performance gets bad!

I need an implementation like the TrackBallInfoCursor! Can you give me a hint?

Hello,

I asked about this a year ago, but now I see from the release notes that this is now supported in Silverlight, but I cannot find any documentation for this. Does it exist anywhere yet?

Thanks very much,

Martyn.

Hallo,

i have a problem with displaying large values in chart view.

When i load my data set from server i get e.g. 1000 data point. one of this points have the value 730000000.83

The MaxZoom property is set to 5000000,5000000.

When you completely zoom in all the small values are hidden/not displayed in grid. The only line you can see is the line of the first value (730000000.83)

ID          Time                                     Value

52510    2012-06-06 17:30:50.000    730000000.83
52511    2012-06-06 18:00:50.000    71.97
52512    2012-06-06 18:30:50.000    70.12
52513    2012-06-06 18:45:50.000    79.19
52514    2012-06-06 19:00:50.000    78.26
52515    2012-06-06 19:15:50.000    77.33
52516    2012-06-06 19:30:50.000    76.4
52517    2012-06-06 19:45:50.000    75.47
52518    2012-06-06 20:00:50.000    74.54
52519    2012-06-06 20:15:50.000    73.61

In RadCartesianChart, there is an error when displaying multiple AreaSeries with CombineMode = Stack. A stack is formed incorrectly if there are negative values in the AreaSeries. 

For category 2, the value must be 3 + (-5) = -2. But not -5

Hi,

I need to plot more than one BarSeries in Stack combine mode.

Example :
- One vertical Y-Axis and one horizontal X-Axis,
- Two BarSeries in stack mode
- Two other BarSeries in stack mode.

When I implement this, the result is 1 Bar divided in 4, not 1 Bar divided in 2 and another one Bar divided in 2.

I know the way to identify the Bar in stack mode is the vertical axis but Is there an other way ?

Thank you,
Vincent.

Hello! Is there а way to calculate distance between left, right edges of chart control and left, right edges of plot area? Also i need the event, raised when this edges are changing. I've found the property PlotAreaClip and the event PlotAreaClipChanged, but i don't understand how they works. PlotAreaClip.X returns value greater that i need and it rises every time I zoom a chart in.

I've attached the picture.

Hi! I'm trying to improve the design of CartesianGridLineAnnotation label (add background border, for example). I've written that code: 

<telerik:CartesianGridLineAnnotation Axis="{Binding ElementName=horizontalAxis}"  Value="2.8" Stroke="Blue" Label="123" StrokeThickness="1">
        <telerik:CartesianGridLineAnnotation.LabelDefinition>
                        <telerik:ChartAnnotationLabelDefinition>
                            <telerik:ChartAnnotationLabelDefinition.Template>
                                <DataTemplate>
                                    <TextBlock Text="{Binding}" />
                                </DataTemplate>
                            </telerik:ChartAnnotationLabelDefinition.Template>
                        </telerik:ChartAnnotationLabelDefinition>
                    </telerik:CartesianGridLineAnnotation.LabelDefinition>
                </telerik:CartesianGridLineAnnotation>

It seems like Text="{Binding}" doesn't works, because chart doesn't display any text. But it will display it if i replace {Binding} with some value. I've checked the binding state, by the way. It' works fine (attached picture).

I managed to play this problem on your example: https://github.com/telerik/xaml-sdk/tree/master/ChartView/SL/AnnotationsAdding. Version: 2016.2.613.1050.
