Quick Start

// Initialize with sample data
var graph = new SparklineGraph();
await graph.AddDataPointAsync(42.5f);

// Configure alerts
graph.ThresholdValue = 40;
graph.ThresholdReached += (s, val) => 
    MessageBox.Show($"Threshold breached: {val}");

// Enable features
graph.ShowStatistics = true;
graph.SmoothLines = true;
graph.MaxDataPoints = 100;

// Use controller UI
var controller = new SparklineGraphController();
controller.SelectedGraph = graph;

Integration Tips

• Controller UI: Drag SparklineGraphController onto forms for live editing
• High-Frequency Data: Use UpdateDataAsync for batch updates
• Styling: Set LineColor/GridColor for theme matching
• Thresholds: Set ThresholdValue to float.NaN to disable
