BorderColor on LinearAxis Shows on Label

[Laura]

Hi,

 

I would like to change the color of the Axis line, but when I set the BorderColor, I get a border around the label that matches the color I am setting for the Axis line.  I don't want a border around the label, I just want to change the color of the line.  How do I do that?  

This is the code: linearAxis1.BorderColor = System.Drawing.Color.FromArgb(((int)(((byte)(52)))), ((int)(((byte)(143)))), ((int)(((byte)(142)))));

Hello Laura,

Thank you for writing.

The axis children are inheriting the border color and in this case you must set their border color as well:

foreach (var item in verticalAxis.Children)
{
    item.BorderColor = Color.Transparent;
}

Please let me know if there is something else I can help you with.

Thank you Dimitar!  This worked perfectly, though I did have to change it just slightly to also change the backcolor of the item, then all worked well.

foreach (var item in verticalAxis.Children)

{    

item.BorderColor = Color.Transparent;
item.BackColor = Color.Transparent;

}

Cycling the Axis.Children works if your axis are static, if you however are sending live data to you chart and your axis change, it puts all the borders back around the labels again.  I tried cycling the children after changing the min and max values, but no luck in keeping the borders around the labels hidden.

Hello Roger,

You can use custom renderer for this case. Here is a sample implementation:

public class CustomCartesianRenderer : CartesianRenderer
{
    public CustomCartesianRenderer(CartesianArea area)
        : base(area)
    { }
    protected override void Initialize()
    {
        base.Initialize();
        for (int i = 0; i < this.DrawParts.Count; i++)
        {
            AxisLabelDrawPart part = this.DrawParts[i] as AxisLabelDrawPart;
            if (part != null && part.Element is CategoricalAxis)
            {
                this.DrawParts[i] = new MyAxisLabelDrawPart((CategoricalAxis)part.Element, this);
            }
        }
    }
}
class MyAxisLabelDrawPart : AxisLabelDrawPart
{
    public MyAxisLabelDrawPart(Axis axis, IChartRenderer renderer) : base(axis, renderer)
    { }
    protected override void DrawNoneAndMultiLineLabelElements()
    {

        foreach (var item in this.Element.Children)
        {

            item.BorderWidth = 0;
        }
        base.DrawNoneAndMultiLineLabelElements();
    }
}

The default renderer can be changed in the CreateRenderer event handler:

void radChartView1_CreateRenderer(object sender, ChartViewCreateRendererEventArgs e)
{
    e.Renderer = new CustomCartesianRenderer(e.Area as CartesianArea);
}

I hope this will be useful. Let me know if you have additional questions.

Not to sound negative by any means, but this seems excessive to be able to remove the borders on labels. Based on my understanding, are inherited from the axis border.

Suggested upgrade idea, would resolve my issue here.

HorizontalAxis.LabelBorder.Visible = False

VerticalAxis.LabelBorder.Visible = False
