Hi,

The default legend shape is Rectangle. I would like to show Line in the legend. I cannot show other shapes for Line chart. I see Line is not supported in Legend.
I see from other post(other products of Telerik), the alternate way. But none of those works for Telerik reports.

Here is what i'm doing following other post, to show the legend as Line.
Telerik.Reporting.Charting.LabelItem wirlegendItem = new Telerik.Reporting.Charting.LabelItem(WIRseries.Name);
wirlegendItem.Marker.Appearance.FillStyle.MainColor = System.Drawing.Color.Black;
wirlegendItem.Marker.Appearance.Figure = Telerik.Reporting.Charting.Styles.DefaultFigures.Rectangle;
wirlegendItem.Marker.Appearance.FillStyle.FillType = Telerik.Reporting.Charting.Styles.FillType.Solid;
wirlegendItem.Marker.Appearance.Dimensions.Margins.Top = Telerik.Reporting.Charting.Styles.Unit.Pixel(0);
wirlegendItem.Marker.Appearance.Dimensions.Margins.Bottom = Telerik.Reporting.Charting.Styles.Unit.Pixel(0);
wirlegendItem.Marker.Appearance.Dimensions.Margins.Left = Telerik.Reporting.Charting.Styles.Unit.Pixel(5);
wirlegendItem.Marker.Appearance.Dimensions.Margins.Right = Telerik.Reporting.Charting.Styles.Unit.Pixel(5);
wirlegendItem.Marker.Appearance.Dimensions.Paddings.Top = Telerik.Reporting.Charting.Styles.Unit.Pixel(5);
wirlegendItem.Marker.Appearance.Dimensions.Paddings.Bottom = Telerik.Reporting.Charting.Styles.Unit.Pixel(5);
wirlegendItem.Marker.Appearance.Dimensions.Paddings.Left = Telerik.Reporting.Charting.Styles.Unit.Pixel(0);
wirlegendItem.Marker.Appearance.Dimensions.Paddings.Right = Telerik.Reporting.Charting.Styles.Unit.Pixel(0);
this.chtWFRWIR.Legend.Items.Add(wirlegendItem);

Is there any alternative to achieve this?


Thanks

Hello Sivam,

We've already answered your inquiry in your support ticket, but would post the answer here in case anyone else is interested:

"The only way to achieve this would be if you construct the chart entirely programmatically i.e. the chart is not bound through the DataSource property, thus you manually specify the column for XAxis YAxis, labels etc. You can find such example in the following article: Data Binding Chart to a Generic List of Objects. Then you would be able to simulate a line in the legend with the following code:

Copy Code
RadChart1.Legend[0].Marker.Appearance.Dimensions.AutoSize = false;
RadChart1.Legend[0].Marker.Appearance.Figure = "Rectangle";
RadChart1.Legend[0].Marker.Appearance.Dimensions.Height = Telerik.Charting.Styles.Unit.Pixel(2);
RadChart1.Legend[0].Marker.Appearance.Dimensions.Width = Telerik.Charting.Styles.Unit.Pixel(20);

Since we cannot show a line out of the box, we simulate this by showing a rectangle without border which has height of 1 or 2 pixels effectively rendering a line.

All the best,
Steve
