SplineArea color ?

[Grtjn]

Hi,

Using the Q1 2010 version, i can't seem to set the colors and other layout settings of the spileAreaSeries.

ineChart.DefaultSeriesDefinition.Appearance.Fill = new SolidColorBrush(Colors.LightGray);
            LineChart.DefaultSeriesDefinition.Appearance.StrokeThickness = 4;
            LineChart.DefaultSeriesDefinition.Appearance.Fill.Opacity = 0.5;
LineChart.DefaultSeriesDefinition.Appearance.PointMark.Fill = new SolidColorBrush(Colors.Transparent);
            LineChart.DefaultSeriesDefinition.Appearance.PointMark.Stroke = new SolidColorBrush(Colors.White);
            LineChart.DefaultSeriesDefinition.Appearance.PointMark.StrokeThickness = 1.75;
            LineChart.DefaultSeriesDefinition.Appearance.PointMark.Shape = MarkerShape.SquareRounded;

Any help ?

Kind regards,

Gertjan

Hi Grtjn,

The RadChart.DefaultSeriesDefintion property is effective only in databound scenarios:

SplineAreaSeriesDefinition definition = new SplineAreaSeriesDefinition();
definition.Appearance.Fill = new SolidColorBrush(Colors.LightGray);
definition.Appearance.Fill.Opacity = 0.5;
definition.Appearance.StrokeThickness = 4;
definition.Appearance.PointMark.Fill = new SolidColorBrush(Colors.Transparent);
definition.Appearance.PointMark.Stroke = new SolidColorBrush(Colors.White);
definition.Appearance.PointMark.StrokeThickness = 1.75;
definition.Appearance.PointMark.Shape = MarkerShape.SquareRounded;

RadChart1.DefaultSeriesDefinition = definition;
RadChart1.ItemsSource = new int[] { 40, 30, 20, 50 };

We suspect that you are using the control in un-bound mode -- in this case you need to set the SeriesDefinition on the DataSeries itself:

SplineAreaSeriesDefinition definition = new SplineAreaSeriesDefinition();
definition.Appearance.Fill = new SolidColorBrush(Colors.LightGray);
definition.Appearance.Fill.Opacity = 0.5;
definition.Appearance.StrokeThickness = 4;
definition.Appearance.PointMark.Fill = new SolidColorBrush(Colors.Transparent);
definition.Appearance.PointMark.Stroke = new SolidColorBrush(Colors.White);
definition.Appearance.PointMark.StrokeThickness = 1.75;
definition.Appearance.PointMark.Shape = MarkerShape.SquareRounded;

DataSeries series = new DataSeries();
series.Definition = definition;
series.Add(new DataPoint(40));
series.Add(new DataPoint(30));
series.Add(new DataPoint(20));
series.Add(new DataPoint(50));

RadChart1.DefaultView.ChartArea.DataSeries.Add(series);

Hope this helps.
