FastCharts is a high-performance .NET charting library designed for real-time applications, financial dashboards, and data visualization scenarios requiring smooth rendering of massive datasets (10M+ points).
⚡ Key Features
🚀 Real-time Performance: 60 FPS rendering with LTTB decimation
using FastCharts.Core;
using FastCharts.Core.Series;
// Create chart model
var model = new ChartModel();
// Add data series
model.AddSeries(new LineSeries(new[] {
new PointD(0, 10),
new PointD(1, 20),
new PointD(2, 15),
new PointD(3, 25)
}) {
Title = "Sales Data",
Color = ColorRgba.Blue,
StrokeWidth = 2
});
// Bind to your ViewModel
this.DataContext = new { ChartModel = model };
Real-Time Streaming Example
// Create streaming series with rolling window
var streamingSeries = new StreamingLineSeries {
Title = "Live Data",
MaxPointCount = 1000, // Keep last 1000 points
RollingWindowDuration = TimeSpan.FromMinutes(5)
};
// Add real-time data
streamingSeries.AppendPoint(new PointD(DateTime.Now.Ticks, sensorValue));
model.AddSeries(streamingSeries);
Multi-Axis Example
// Create chart with multiple Y axes
var model = new ChartModel();
// Add left axis series (temperature)
model.AddSeries(new LineSeries(temperatureData) {
Title = "Temperature (°C)",
YAxisIndex = 0, // Left Y axis
Color = ColorRgba.Red
});
// Add right axis series (pressure)
model.AddSeries(new LineSeries(pressureData) {
Title = "Pressure (hPa)",
YAxisIndex = 1, // Right Y axis
Color = ColorRgba.Blue
});
