C# WPF图纸发布

我想在WPF中绘制多段线。但它只显示了一个点，因为点之间的差异非常小。我也应用了scaleTransform和TranslateTransform，但问题仍然是一样的

代码是

double minX = 25.52524938052284;
double minY = 44.267051317656474;
double maxX = 25.525239580522843;
double maxY = 44.26684671765647;
System.Windows.Point point1 = new System.Windows.Point(minX, minY);
System.Windows.Point point2 = new System.Windows.Point(maxX, maxY);

Polyline myPolyline = new Polyline();
myPolyline.Stroke = System.Windows.Media.Brushes.SaddleBrown;
myPolyline.StrokeThickness = 1;

polylinePointCollection.Add(point1);
polylinePointCollection.Add(point2);

ScaleTransform st = new ScaleTransform(100000,100000,25,25);
myPolyline.RenderTransform = st;
TranslateTransform tt = new TranslateTransform(100, 100);
myPolyline.RenderTransform = tt;
canvas.Children.Add(myPolyline);

这是示例代码。我有一个从15到20的点列表，所以坐标之间的这个小的基本差异必须显示在屏幕上，但它只显示一个点。

您正在处理一些非常小的差异，因此，变换坐标非常敏感。考虑你的代码并做一些小的调整，考虑以下内容：
