BarSeries on DateTimeContinousAxys

[Marcello]

Hi,

Is possible to set manually the columns width?
Look this example, all columns is overlappeds!

<telerik:RadCartesianChart>
            <telerik:RadCartesianChart.HorizontalAxis>
                <telerik:DateTimeContinuousAxis MaximumTicks="5" PlotMode="OnTicksPadded"/>
            </telerik:RadCartesianChart.HorizontalAxis>
            <telerik:RadCartesianChart.VerticalAxis>
                <telerik:LinearAxis/>
            </telerik:RadCartesianChart.VerticalAxis>
            <telerik:BarSeries Name="mS">

            </telerik:BarSeries>
            <telerik:RadCartesianChart.Behaviors>

                <telerik:ChartPanAndZoomBehavior/>
            </telerik:RadCartesianChart.Behaviors>
        </telerik:RadCartesianChart>

public MainWindow()
        {
            InitializeComponent();

            for (int i = 0; i < 100;i++ )
                mS.DataPoints.Add(new Telerik.Charting.CategoricalDataPoint() { Category = System.DateTime.Today.AddDays(i), Value = 5 });

        }

Hi Marcello,

The width of the BarSeries items, depends on the size of the step between axis ticks. You can use the MajorStepUnit and MajorStep properties to adjust it. Here is an example: 

<telerik:RadCartesianChart Palette="Windows8">
    <telerik:RadCartesianChart.HorizontalAxis>
        <telerik:DateTimeContinuousAxis MaximumTicks="5"
                              PlotMode="OnTicksPadded"
                              MajorStepUnit="Day"
                              MajorStep="1"
                              LabelInterval="10"
                              LabelFitMode="Rotate"
                              LabelRotationAngle="-90"/>
    </telerik:RadCartesianChart.HorizontalAxis>

    <telerik:RadCartesianChart.VerticalAxis>
        <telerik:LinearAxis/>
    </telerik:RadCartesianChart.VerticalAxis>

    <telerik:BarSeries Name="mS" PaletteMode="DataPoint"/>

    <telerik:RadCartesianChart.Behaviors>
        <telerik:ChartPanAndZoomBehavior/>
    </telerik:RadCartesianChart.Behaviors>
</telerik:RadCartesianChart>

I have attached a screenshot for reference.

I hope this was the solution you were looking for.

Hi kirov,

Ok, so for Bar Column usage is mandatory to set manually the Axis Plot Properties.
But this create a lot of problems.
Please look my other post in http://www.telerik.com/community/forums/wpf/chart/datetimecontinuousaxis-ticks.aspx#2695711

Thank's

Hi Marc,

I have attached a project that shows another approach - BarSeries with PointTemplate with data-bound Width property. This allows you modify the bar width directly when needed (eg. when the ZoomChanged event occurs). Additionally, you may find useful the RadCartesianChart.PlotAreaClip.Width property, which you can use to get the available plot area space.

I hope this helps.
