示例1: OnRender
protected override void OnRender(DrawingContext dc)
{
dc.DrawRectangle(Brushes.Transparent, null, new Rect(0, 0, RenderSize.Width, RenderSize.Height));
if (_currentPoint == null) return;
if (_lines == null || 0 == _lines.Count) return;
var count = _lines.Count;
var mouse = _currentPoint.Value;
_valueIndex = GetCurrentIndex(mouse);
if (_valueIndex < 0) return;
if (_pen == null)
{
_pen = this.GetDashPen(Brushes.DarkGray);
_pen.Freeze();
}
var height = RenderSize.Height - 20; // 20 上方日期占位
var values = new Dictionary<double, string>();
for (var i = 0; i < count; i++)
