Plotly Chart Components

Interactive visualization components using Plotly.js for the Atomizer Dashboard.

Overview

These components provide enhanced interactivity compared to Recharts:

• Native zoom, pan, and selection
• Export to PNG/SVG
• Hover tooltips with detailed information
• Brush filtering (parallel coordinates)
• 3D visualization support

Components

PlotlyParallelCoordinates

Multi-dimensional data visualization showing relationships between all variables.

import { PlotlyParallelCoordinates } from '../components/plotly';

<PlotlyParallelCoordinates
  trials={allTrials}
  objectives={studyMetadata.objectives}
  designVariables={studyMetadata.design_variables}
  paretoFront={paretoFront}
  height={450}
/>

Props:

Prop	Type	Description
trials	Trial[]	All trial data
objectives	Objective[]	Objective definitions
designVariables	DesignVariable[]	Design variable definitions
paretoFront	Trial[]	Pareto-optimal trials (optional)
height	number	Chart height in pixels

Features:

• Drag on axes to filter data
• Double-click to reset filters
• Color coding: FEA (blue), NN (orange), Pareto (green)

PlotlyParetoPlot

2D/3D scatter plot for Pareto front visualization.

<PlotlyParetoPlot
  trials={allTrials}
  paretoFront={paretoFront}
  objectives={studyMetadata.objectives}
  height={350}
/>

Props:

Prop	Type	Description
trials	Trial[]	All trial data
paretoFront	Trial[]	Pareto-optimal trials
objectives	Objective[]	Objective definitions
height	number	Chart height in pixels

Features:

• Toggle between 2D and 3D views
• Axis selector for multi-objective problems
• Click to select trials
• Hover for trial details

PlotlyConvergencePlot

Optimization progress over trials.

<PlotlyConvergencePlot
  trials={allTrials}
  objectiveIndex={0}
  objectiveName="weighted_objective"
  direction="minimize"
  height={350}
/>

Props:

Prop	Type	Description
trials	Trial[]	All trial data
objectiveIndex	number	Which objective to plot
objectiveName	string	Objective display name
direction	'minimize' | 'maximize'	Optimization direction
height	number	Chart height
showRangeSlider	boolean	Show zoom slider

Features:

• Scatter points for each trial
• Best-so-far step line
• Range slider for zooming
• FEA vs NN differentiation

PlotlyParameterImportance

Correlation-based parameter sensitivity analysis.

<PlotlyParameterImportance
  trials={allTrials}
  designVariables={studyMetadata.design_variables}
  objectiveIndex={0}
  objectiveName="weighted_objective"
  height={350}
/>

Props:

Prop	Type	Description
trials	Trial[]	All trial data
designVariables	DesignVariable[]	Design variables
objectiveIndex	number	Which objective
objectiveName	string	Objective display name
height	number	Chart height

Features:

• Horizontal bar chart of correlations
• Sort by importance or name
• Color: Red (positive), Green (negative)
• Pearson correlation coefficient

Bundle Optimization

To minimize bundle size, we use:

1. plotly.js-basic-dist: Smaller bundle (~1MB vs 3.5MB)

   • Includes: scatter, bar, parcoords
   • Excludes: 3D plots, maps, animations

2. Lazy Loading: Components loaded on demand

   const PlotlyParetoPlot = lazy(() =>
     import('./plotly/PlotlyParetoPlot')
       .then(m => ({ default: m.PlotlyParetoPlot }))
   );
   

3. Code Splitting: Vite config separates Plotly into its own chunk

   manualChunks: {
     plotly: ['plotly.js-basic-dist', 'react-plotly.js']
   }
   

Usage with Suspense

Always wrap Plotly components with Suspense:

<Suspense fallback={<ChartLoading />}>
  <PlotlyParetoPlot {...props} />
</Suspense>

Type Definitions

interface Trial {
  trial_number: number;
  values: number[];
  params: Record<string, number>;
  user_attrs?: Record<string, any>;
  source?: 'FEA' | 'NN' | 'V10_FEA';
}

interface Objective {
  name: string;
  direction?: 'minimize' | 'maximize';
  unit?: string;
}

interface DesignVariable {
  name: string;
  unit?: string;
  min?: number;
  max?: number;
}

Styling

Components use transparent backgrounds for dark theme compatibility:

• paper_bgcolor: 'rgba(0,0,0,0)'
• plot_bgcolor: 'rgba(0,0,0,0)'
• Font: Inter, system-ui, sans-serif
• Grid colors: Tailwind gray palette

Export Options

All Plotly charts include a mode bar with:

• Download PNG
• Download SVG (via menu)
• Zoom, Pan, Reset
• Auto-scale

Configure export in the config prop:

config={{
  toImageButtonOptions: {
    format: 'png',
    filename: 'my_chart',
    height: 600,
    width: 1200,
    scale: 2
  }
}}
