How to draw a smooth curved line in WPF?
.net, c#, canvas, wpf
Solution
I think you are looking for splines

Gabe is correct that is from Forms
Under WPF you could try a PolyBezierSegment but it require 4 points. Possible you could put in three points and 1 more to shape it.
<Canvas>
<Path Stroke="Black" StrokeThickness="10">
<Path.Data>
<PathGeometry>
<PathGeometry.Figures>
<PathFigureCollection>
<PathFigure StartPoint="100,80">
<PathFigure.Segments>
<PathSegmentCollection>
<PolyBezierSegment Points="90,200 140,200 160,200 180,200 430,190 430,280" />
</PathSegmentCollection>
</PathFigure.Segments>
</PathFigure>
</PathFigureCollection>
</PathGeometry.Figures>
</PathGeometry>
</Path.Data>
</Path>
</Canvas>
This results in the following curve
Problem
I have three known positions, and currently I am driving two lines like so: ``` Line line = new Line { StrokeThickness = 3, Stroke = lineColor, X1 = MyX, Y1 = MyY, X2 = MyX, Y2 = MiddleY }; Graph.Children.Add(line); line = new Line { StrokeThickness = 3, Stroke = lineColor, X1 = MyX, Y1 = MiddleY, X2 = TargetX, Y2 = TargetY }; Graph.Children.Add(line); ``` Here's the result: So, as you can see, this is almost what I want except that I want it to be more smoothed out, just a little bit. Now I'm looking for any way I could set three points, set some smooth/curvy level to the middle point and then draw a line with a solid color on it. Much like how I can do this in Photoshop: Or at least get a similar kind of smoothness.
