PowerBuilder HTML Dashboard with Chart.js

This example demonstrates integrating a responsive HTML dashboard within PowerBuilder applications, combining business logic with Chart.js visualization capabilities.

What This Example Provides

• Dynamic cards and interactive charts generated from PowerBuilder
• Responsive design using Flexbox
• Professional charts with Chart.js
• Interactive cards that execute PowerBuilder functions
• Object-oriented architecture for easy reuse

Architecture Overview

Three-component structure:

• Base Class (n_cst_dashboard): Generates HTML/CSS, defines card sizes and chart types
• Specialized Classes: Inherit from base, define specific data (sales, purchases, etc.)
• Data Structures: Organize information for dynamic HTML construction

Key Features

• Dynamic Theme Integration: Automatically detects PowerBuilder's active theme and applies matching CSS colors
• PowerBuilder ↔ JavaScript Interactivity: Card clicks trigger PowerBuilder functions via WebBrowser events
• Responsive Layout: Cards redistribute based on window size, charts occupy full width

Example Implementation: Sales Dashboard

Includes:

• 4 KPI cards (budgets, orders, delivery notes, invoices)
• Monthly billing comparison chart (current vs. previous year)
• Note: Some data is mock for demonstration; invoices use real database queries

Benefits

• Reusable: Easy to create dashboards for different business areas
• Extensible: Simple to add new charts or cards
• Modern UI: Professional appearance with hover effects and shadows
• Fully Integrated: Maintains PowerBuilder robustness with web flexibility
