Documentation: DTS.Viewer.Graph Views

1. Purpose

This module provides WPF view components for graph and chart visualization within the DTS Viewer application. It contains three partial classes—GraphView, TestDataView, and TestDataSeriesView—that serve as code-behind files for their respective XAML views. These views implement interfaces from DTS.Common.Interface and provide chart rendering, user interaction handling, and export functionality (PDF and CSV) for test data series visualization.

---

2. Public Interface

GraphView

Signature: public partial class GraphView : IGraphView

• GraphView() - Constructor. Calls InitializeComponent() to load the XAML-defined UI.

---

TestDataView

Signature: public partial class TestDataView : ITestDataView

• TestDataView() - Constructor. Calls InitializeComponent() to load the XAML-defined UI.

---

TestDataSeriesView

Signature: public partial class TestDataSeriesView : ITestDataSeriesView

• TestDataSeriesView() - Constructor. Calls InitializeComponent() to load the XAML-defined UI.

• bool SaveReportToPDF(string directory) - Generates a PDF report containing the chart image and a gRMS data table. Returns true on success, false on failure. Creates the directory if it does not exist. Logs success/failure via APILogger.

• bool SaveReportToCSV(string directory) - Exports chart data to a CSV file with frequency and PSD values. Returns true on success, false on failure. Creates the directory if it does not exist. Logs success/failure via APILogger.

---

AxisExtension (Static Class)

Signature: public static class AxisExtension

• double GetDispMin(this Axis axis) - Extension method that calculates the displayed minimum value based on ActualMin, ActualMax, Value, and Scale properties.

• double GetDispMax(this Axis axis) - Extension method that calculates the displayed maximum value based on ActualMin, ActualMax, Value, and Scale properties.

---

3. Invariants

• SaveReportToPDF: The directory parameter must not be null, empty, or whitespace; otherwise, a DirectoryNotFoundException is thrown.
• SaveReportToPDF: MainChart.DataContext must be castable to TestDataSeriesViewModel; a direct cast is performed without null checking.
• SaveReportToPDF: GraphDataSeries must contain at least one element (accesses dataSeries[0] for test setup name and test ID).
• SaveReportToCSV: All data series in GraphDataSeries must have Xvalue and Yvalue arrays of equal or greater length than
