I have some chart and I want to add dynamicly LineSeries without DataPoints, just lines with some custom colors. The only way I found to hide data points is:
Style style = new Style(typeof(LineDataPoint));
style.Setters.Add(new Setter(LineDataPoint.TemplateProperty, null));
var series = new LineSeries()
{
Title = name,
DependentValuePath = "Y",
IndependentValuePath = "X",
ItemsSource = new ObservableCollection<FloatingPoint>(),
DataPointStyle = style,
};
Unfortunately when I do this all lines become yellow and I can't change their colors. I tried to do this:
Style style = new Style(typeof(LineDataPoint));
style.Setters.Add(new Setter(LineDataPoint.TemplateProperty, null));
SolidColorBrush brush = new SolidColorBrush(Colors.Red);
var series = new LineSeries()
{
Title = name,
DependentValuePath = "Y",
IndependentValuePath = "X",
ItemsSource = new ObservableCollection<FloatingPoint>(),
DataPointStyle = style,
Background = brush,
};
But it doesn't help - I can't change line color... Even if I write
series.Background = brush;
Try this.
series = new LineSeries();
Style dataPointStyle = GetNewDataPointStyle();
series.DataPointStyle = dataPointStyle;
/// <summary>
/// Gets the new data point style.
/// </summary>
/// <returns></returns>
private static Style GetNewDataPointStyle()
{
Color background = Color.FromRgb((byte)random.Next(255),
(byte)random.Next(255),
(byte)random.Next(255));
Style style = new Style(typeof(DataPoint));
Setter st1 = new Setter(DataPoint.BackgroundProperty,
new SolidColorBrush(background));
Setter st2 = new Setter(DataPoint.BorderBrushProperty,
new SolidColorBrush(Colors.White));
Setter st3 = new Setter(DataPoint.BorderThicknessProperty, new Thickness(0.1));
Setter st4 = new Setter(DataPoint.TemplateProperty, null);
style.Setters.Add(st1);
style.Setters.Add(st2);
style.Setters.Add(st3);
style.Setters.Add(st4);
return style;
}
