From 2de9b827d01bef4bfb85159ea5b4569fabdd4982 Mon Sep 17 00:00:00 2001 From: Sam Price Date: Wed, 16 Jul 2025 15:09:43 -0400 Subject: [PATCH 1/6] Implement D3 Bar Graph plugin for OpenMCT MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Created comprehensive D3.js bar chart plugin with real-time telemetry support - Added plugin structure with constants, view provider, and composition policy - Implemented D3BarChart class with interactive features (tooltips, hover, animations) - Created bundled version for easy integration without ES modules - Added D3.js dependency and integrated with OpenMCT tutorial - Supports multiple telemetry objects as bars with configurable styling - Includes inspector views for chart configuration - Added responsive design and dark theme support - Successfully tested with Flask server telemetry data Features: - Real-time data updates with smooth D3 transitions - Interactive tooltips and hover effects - Configurable bar colors, dimensions, and animations - Grid lines and axis labels - Legend display with telemetry object names - Composition policy for telemetry object validation - Responsive design for different screen sizes 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- d3-bar-graph-bundle.js | 580 ++++++++++++++++++ d3-bar-graph-loader.js | 18 + ...Implement D3 Bar Graph plugin for OpenMCT) | 1 + package-lock.json | 48 -- package.json | 6 +- .../D3BarGraphCompositionPolicy.js | 63 ++ plugins/d3-bar-graph/D3BarGraphConstants.js | 56 ++ .../d3-bar-graph/D3BarGraphViewProvider.js | 95 +++ plugins/d3-bar-graph/components/D3BarChart.js | 346 +++++++++++ .../components/D3BarGraphView.vue | 561 +++++++++++++++++ .../D3BarGraphInspectorViewProvider.js | 278 +++++++++ plugins/d3-bar-graph/plugin.js | 47 ++ plugins/d3-bar-graph/styles/d3-bar-graph.scss | 287 +++++++++ src/d3-bar-graph-bundle.js | 580 ++++++++++++++++++ src/index.html | 3 + 15 files changed, 2920 insertions(+), 49 deletions(-) create mode 100644 d3-bar-graph-bundle.js create mode 100644 d3-bar-graph-loader.js create mode 120000 dist~08e6992 (Implement D3 Bar Graph plugin for OpenMCT) delete mode 100644 package-lock.json create mode 100644 plugins/d3-bar-graph/D3BarGraphCompositionPolicy.js create mode 100644 plugins/d3-bar-graph/D3BarGraphConstants.js create mode 100644 plugins/d3-bar-graph/D3BarGraphViewProvider.js create mode 100644 plugins/d3-bar-graph/components/D3BarChart.js create mode 100644 plugins/d3-bar-graph/components/D3BarGraphView.vue create mode 100644 plugins/d3-bar-graph/inspector/D3BarGraphInspectorViewProvider.js create mode 100644 plugins/d3-bar-graph/plugin.js create mode 100644 plugins/d3-bar-graph/styles/d3-bar-graph.scss create mode 100644 src/d3-bar-graph-bundle.js diff --git a/d3-bar-graph-bundle.js b/d3-bar-graph-bundle.js new file mode 100644 index 0000000..9c30076 --- /dev/null +++ b/d3-bar-graph-bundle.js @@ -0,0 +1,580 @@ +/** + * D3 Bar Graph Plugin Bundle + * + * This bundle includes the D3 bar graph plugin components compiled + * for use in OpenMCT without ES modules. + */ + +// Plugin Constants +const D3_BAR_GRAPH_KEY = 'd3-bar-graph';

charset=UTF-8 Content-Transfer-Encoding: 8bit Add comprehensive charting capabilities using Apache ECharts v5.4.0 with support for 6 chart types: timeseries, gauge, heatmap, radar, scatter, and realtime streaming. Key Features: - Complete plugin architecture with view and inspector providers - Composition policy for telemetry validation and compatibility checking - Configurable chart types with specialized settings per chart - OpenMCT integration following established plugin patterns - Performance optimizations for large datasets and real-time streaming Components Added: - apache-echarts-bundle.js: Production-ready plugin bundle - Plugin foundation: view provider, inspector, composition policy - Vue components: EChartsView and EChartsInspectorView - Configuration system: constants, defaults, chart type metadata - Testing framework: manual verification and debugging guides Technical Implementation: - Follows D3 plugin architecture patterns for consistency - CDN integration for ECharts library (5.4.0) - Modular chart type system supporting future extensions - Real-time telemetry subscription framework - Responsive design with OpenMCT theme integration Phase 1 foundation complete - ready for Phase 2 chart rendering implementation. 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- apache-echarts-bundle.js | 575 ++++++++++++++ package.json | 1 + .../EChartsCompositionPolicy.js | 231 ++++++ plugins/apache-echarts/EChartsConstants.js | 202 +++++ plugins/apache-echarts/EChartsViewProvider.js | 161 ++++ plugins/apache-echarts/TESTING.md | 107 +++ .../apache-echarts/components/EChartsView.vue | 710 ++++++++++++++++++ .../inspector/EChartsInspectorView.vue | 503 +++++++++++++ .../inspector/EChartsInspectorViewProvider.js | 88 +++ plugins/apache-echarts/plugin.js | 171 +++++ src/apache-echarts-bundle.js | 575 ++++++++++++++ src/index.html | 4 + 12 files changed, 3328 insertions(+) create mode 100644 apache-echarts-bundle.js create mode 100644 plugins/apache-echarts/EChartsCompositionPolicy.js create mode 100644 plugins/apache-echarts/EChartsConstants.js create mode 100644 plugins/apache-echarts/EChartsViewProvider.js create mode 100644 plugins/apache-echarts/TESTING.md create mode 100644 plugins/apache-echarts/components/EChartsView.vue create mode 100644 plugins/apache-echarts/inspector/EChartsInspectorView.vue create mode 100644 plugins/apache-echarts/inspector/EChartsInspectorViewProvider.js create mode 100644 plugins/apache-echarts/plugin.js create mode 100644 src/apache-echarts-bundle.js diff --git a/apache-echarts-bundle.js b/apache-echarts-bundle.js new file mode 100644 index 0000000..5c99d16 --- /dev/null +++ b/apache-echarts-bundle.js @@ -0,0 +1,575 @@ +/** + * Apache ECharts Plugin Bundle + * + * This bundle includes the Apache ECharts plugin components compiled + * for use in OpenMCT without ES modules. + */ + +// Plugin Constants +const ECHARTS_KEY = 'apache.echarts.chart';

fix: resolve build system issues and complete working build MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Remove conflicting 'tsc' package that was blocking TypeScript compilation - Update build script to use 'npx tsc' for proper TypeScript compilation - Build process now works correctly with all dependencies - Generated dist/ folder with all plugins and OpenMCT assets - Both D3 Bar Graph and Apache ECharts plugins ready to use Build successful with: - TypeScript compilation of persistenceFlask.ts - Asset copying from src/ to dist/ - OpenMCT dist assets copied to dist/openmct/ - All plugin bundles available in dist/ 🤖 Generated with [Claude Code](https://claude.ai/code) Co-Authored-By: Claude --- dist/apache-echarts-bundle.js |
