Change the Y-AXIS ItemLabel styles at runtime

[vijay]

Hi All,

I am Working with horizontal bar series and I am binding few measures and total to the chart

Meausres as well as Total showing in one graph(Please see the attachment)

For example  Y-axis itemlabels are

Measure1: 10

Measure2: 10

Measure 3:10

Total          : 30

Now my requirement is I have to make the difference for styles of measures and total

So I have to apply the different style to “Total” Item label at runtime.(Like making the total as bold somethig)

I tried but not able to succeed.

Can you people please help me to get the solution for this.

as for the graph here i am using 4 horizontal stack bar series 
series1 is 0 to 25 
series2 is 25 to 50 
series3 is 50 to 75 
series4 is 75 to 100 

and i am binding the chart directly to the list. 

Please verify the attached graph for more clarification.

Thanks in advance

Hi Vijay,

Here is a possible solution for your scenario:

1. Set a custom style where for example you have a setter with red foreground:

<UserControl.Resources>
    <Style x:Key="CustomLabel" TargetType="TextBlock">
        <Setter Property="Foreground" Value="Red" />
        <Setter Property="TextAlignment" Value="Right" />
    </Style>
</UserControl.Resources>

2. On the ChartArea Loaded event you can set this custom style to the first label:

private void ChartArea_Loaded(object sender, EventArgs e)
{
    ChartArea area = sender as ChartArea;

    VerticalAxisLabels2D axisLabelsContainer = area.FindChildByType<VerticalAxisLabels2D>();
    IList<AxisLabel2D> axisLabels = axisLabelsContainer.ChildrenOfType<AxisLabel2D>();
    Style style = this.Resources["CustomLabel"] as Style;

    axisLabels.FirstOrDefault<AxisLabel2D>().ItemLabelStyle = style;
}

Please try the approach above and let us know whether this helps you.
