TDA.GUI 2.1.5

TDA.GUI

English | 简体中文

TDA.GUI is the WinForms visualization package of TDA, a .NET 10 framework for STDF (Standard Test Data Format) semiconductor test data (CP/FT) analysis. It provides interactive trend charts, histograms with statistics annotation, box plots, cumulative probability plots (Normal/LogNormal/Weibull), color-coded Wafer Maps, chart linking, and a high-performance virtual data grid — built on ScottPlot and SkiaSharp.

Install

dotnet add package TDA.GUI

TDA.GUI consumes the TDA core package; TDA.Report adds report generation on top of it.

Controls

All charts inherit from TDABaseChart (title/axis labels, spec-limit lines, SaveImage / CopyImage / ExportCsv, auto title & legend) and consume the UI-agnostic data model TDADataCollection / ITDADataSeries — not DataPrism directly.

Supporting pieces: BinCalculator (Sturges / Scott / Freedman-Diaconis / custom), ProbabilityScale (Benard median-rank ECDF), StatisticsHelper (mean/sigma, quantiles, Cp/Cpk, box-plot stats), WaferCoordinateHelper, ChartLinkingManager (selection sync across charts).

Platform Requirements

• Target framework: net10.0-windows10.0.19041 (Windows only), UseWindowsForms enabled — the consuming project must do the same.
• Depends on the TDA core package, ScottPlot.WinForms and SkiaSharp.

Quick Start

Plot a histogram

using TDA.GUI.Controls;
using TDA.GUI.DataModel;

var data = new TDADataCollection
{
    USL = 1.2, LSL = 0.8, Unit = "V",
    Series =
    {
        new TDADataSeries
        {
            Name = "LotA-Wafer01-Vth",
            Values = new[] { 0.52, 0.49, 0.55, 0.51 /* ... */ },
            Type = DataSeriesType.Raw,
            Metadata = new Dictionary<string, object>
            {
                ["LotId"] = "LotA", ["WaferId"] = "Wafer01", ["Unit"] = "V"
            }
        }
    }
};

var histogram = new HistogramChart { BinMethod = BinMethod.Scott };
histogram.SetData(data);      // bins + Normal fit + spec lines + statistics annotation
histogram.Show();

One-line plot windows

using TDA.GUI;

var form = new EasyPlotForm();        // Trend / Histogram / CDF / BoxPlot / WaferMap tabs
form.PlotHistogram(data);
form.PlotTrend(data);
Application.Run(form);

// or pick a layout dynamically:
var flex = new FlexiblePlotForm(ChartLayout.Trend | ChartLayout.Histogram);
flex.LoadData(data);
flex.Show();

Wafer map (CP data)

using TDA.GUI.Controls;

var waferMap = new WaferMapChart { RtDataMode = MapRtDataMode.OverWrite }; // retest: last result wins
waferMap.SetData(waferMapData);     // WaferMapData: dies + bin info, pass bins bright green
waferMap.Show();

Link selections across charts

using TDA.GUI.Linking;

var linker = new ChartLinkingManager();
linker.Register(trendChart);
linker.Register(histogramChart);    // selecting a range in one highlights it in the other
