OptunaSharp.Visualization.Plotly 1.0.0

OptunaSharp.Visualization.Plotly

The plotly visualization backend for OptunaSharp — a raw-C# port of optuna.visualization (the 12 plot_* functions) built on Plotly.NET, over OptunaSharp's Phase 3.1 visualization data layer.

Figures are plotly.js figures whose spec matches live Optuna's figure.to_dict(), so what you see is what Optuna draws. Pure managed — Plotly.NET pulls only managed dependencies (no native binaries).

using OptunaSharp;
using OptunaSharp.Visualization.Plotly;
using Plotly.NET.CSharp;   // .Show() / .SaveHtml()

var study = Optuna.CreateStudy();
study.Optimize(t => { var x = t.SuggestFloat("x", -10, 10); return (x - 2) * (x - 2); }, nTrials: 50);

PlotlyVisualization.PlotOptimizationHistory(study).SaveHtml("history.html");
PlotlyVisualization.PlotOptimizationHistory(study).Show();   // opens a browser

Customizing (golden-standard Plotly.NET config)

Every Plot* returns a Plotly.NET GenericChart, so configure it the idiomatic way. Most of the fluent surface ships in Plotly.NET core (using Plotly.NET;) — .WithConfig, .WithLayout, .WithSize, .WithTitle, … This package adds the two things it's missing: .WithDisplayOptions and .WithCustomization (a one-call bundle), plus a customization overload on each Plot*:

using Plotly.NET;                       // .WithConfig / .WithSize / .WithLayout (Plotly.NET core)
using OptunaSharp.Visualization.Plotly; // .WithDisplayOptions / .WithCustomization + the overloads

var config = new Config();  config.SetValue("staticPlot", true);
var layout = new Layout();  layout.SetValue("width", 900);   // merged onto Optuna's title/axes

// fluent:
PlotlyVisualization.PlotOptimizationHistory(study).WithConfig(config).WithSize(900, 500);

// or the one-shot overload:
PlotlyVisualization.PlotOptimizationHistory(
    study, new PlotlyChartCustomization { Config = config, Layout = layout });

Status

Complete — all 12 optuna.visualization plot functions are ported (each with a golden-standard Plotly.NET customization overload) and byte-exact vs live Optuna:

PlotOptimizationHistory · PlotEdf · PlotIntermediateValues · PlotHypervolumeHistory · PlotTimeline · PlotParamImportances · PlotSlice · PlotTerminatorImprovement · PlotContour · PlotRank · PlotParallelCoordinate · PlotParetoFront — plus IsAvailable.
