Border color for shape

[Valery]

I am creating ScatterSeries

                    var scatterSeria = new ScatterSeries
                    {
                        XValueMember = "COLUMN0", YValueMember = "COLUMN1", 
                        HorizontalAxis = horizontalAxis1, 
                        VerticalAxis = verticalAxis1,
                        Shape = new CircleShape(),
                        BackColor = Color.Red,
                        BorderColor = Color.Black,
                        PointSize = new SizeF(10.0f, 10.0f),
                        IsVisibleInLegend = true
                    };
But the border of the shape is not drawn in black on the chart. But the same shape is drawn in the legend with a black border.

In a legend, I draw a shape using

        private void LegendElement_VisualItemCreating(object sender, LegendItemElementCreatingEventArgs e)
        {
            e.ItemElement = new LegendItemElement(e.LegendItem);
            if (!(e.LegendItem.Element is ScatterSeries seria)) return;
            e.ItemElement.MarkerElement.Shape = seria.Shape;
        }

How to set the border color for the shape on the chart?

Hello Valery,

In order to see the border over the ScatterPointElements in ScatterSeria, you should set the ScatterPointElement.BorderWidth property:

ScatterSeries scatterSeries = new ScatterSeries()
            {
                BackColor = Color.Red,
                BorderColor = Color.Black,
                Shape = new CircleShape()
            };
foreach (ScatterPointElement point in scatterSeries.Children)
            {
                point.BorderWidth = 1;
            }
            this.radChartView1.Series.Add(scatterSeries);

I hope this helps. If you need any further assistance do not hesitate to ask.

Yes it works. But the problem still remains.

I set the BorderWidth to 0.5f

point.BorderWidth = 0.5f;

but in the legend this BorderWidth is clearly drawn thicker

Hello Valery,

If you want to adjust the border width of the legend elements, you should set the BorderWidth property of the LegendItemElements as well. It is recommended to do this in the Load event of the form:

private void RadForm2_ScatterSeria_Load(object sender, EventArgs e)
        {
            foreach (LegendItemElement item in this.radChartView1.ChartElement.LegendElement.StackElement.Children)
            {
                item.MarkerElement.BorderWidth = 0.5f;
                item.TitleElement.Text = "Legend";
            }
        }

I hope this helps. Should you have further questions I will be glad to help.
