wpf toolkit chart LineSeries DataPointStyle

Question

I want to add LineSeries without points just lines. I want to do this dynamically from code not xaml.

I tried to do this with following code:

Style style = new Style(typeof(LineDataPoint));
style.Setters.Add(new Setter(LineDataPoint.VisibilityProperty,Visibility.Hidden));

var series = new LineSeries()
{
    Title = name,
    DependentValuePath = "Y",
    IndependentValuePath = "X",
    ItemsSource = new ObservableCollection<FloatingPoint>(),
    DataPointStyle = style,
};

chart.Series.Add(series);

However it doesn't work; I still see the points.

Answer 1

I have answered a similar question here .

Briefly: the Visibility property won't work, you should set the Template property to null.

Corrected lines:

Style style = new Style(typeof(LineDataPoint));
style.Setters.Add(new Setter(LineDataPoint.TemplateProperty, null));

Answer 2

In order to hide the data points set width and height to 0 of the same.

  style.Setters.Add(new Setter(LineDataPoint.WidthProperty, 0.0));
  style.Setters.Add(new Setter(LineDataPoint.HeightProperty, 0.0));
