SmartPlot v1.5.0 release artifacts.

SmartPlot V1.4.0 Changelog

Version: SmartPlot 1.4.0
Prepared: 2026-06-02
Source: SmartPlot V1.4 Update Summary 2026-05-31 and the generated V1.4 Word release summary

SmartPlot 1.4.0 focuses on daily plotting workflow speed, reusable figure styling, and a clearer Free / Plus boundary. It adds a settings center, platform-aware shortcuts, local plot style templates, stronger data cleaning, improved import and save flows, composite figures, curve fills, scatter trendlines, update notifications, and new Plus tools for publication-style figure work.

Highlights

• Added a new settings center for appearance, keyboard shortcuts, license status, app information, update checks, and V1.4 release notes.
• Added built-in macOS, Windows, and Linux shortcut sets for common project, editing, data table, view, figure, command, and dialog actions.
• Added SmartPlot Plus custom shortcuts with conflict checks, restore-default behavior, and local persistence.
• Added local Plot Style Templates for SmartPlot Plus, allowing users to save and reuse figure styling without saving source data or column bindings.
• Added global color swatches and a clearer color picker with current color, colors already used in the figure, nearby colors, saved swatches, and empty swatch slots.
• Improved data cleaning with missing-cell removal, missing-row removal, empty-row and empty-column cleanup, duplicate-row removal, trim text, and text-to-number conversion.
• Improved import and save flows so users can choose whether to import into the current project or a new project, and whether to save the current project or all projects.
• Added axis title distance, tick label distance, tick label rotation, and fixes for very small scientific-scale values and manual display-range synchronization.
• Added Composite Figure V1 layouts for 1x2 and 2x1 figures, with editable subplot spacing, optional shared axes, and independent subplot editing.
• Added basic curve fills for line plots and connected scatter plots, including fill-to-baseline, fill-between-lines, opacity, and gradient fills.
• Added scatter and line linear trendline tools from the series inspector, including current-series, multi-Y, and grouped fitting workflows.
• Added generated fit result assets: fitted curve, residual table, parameter table, movable equation label, and an existing-fit-results entry.
• Added app update checks, top-bar update notifications, manual checks in settings, update progress, and relaunch-to-install behavior through the Tauri updater.

Free Updates

Settings and Shortcuts

• Free users can open the settings center, switch Light / Dark appearance, adjust the workspace background, review license status, and view the current version.
• Free users can view and use all built-in keyboard shortcuts.
• Shortcut labels now adapt to the operating system, showing Cmd / Option on macOS and Ctrl / Alt on Windows and Linux.
• Data table shortcuts now cover copy, paste, select all, select current row, select current column, and selection expansion.

Data Cleaning

• Added clearer cleanup actions for common spreadsheet-like problems.
• "Remove missing cells" compresses only the selected columns or selected cell region.
• "Remove missing rows" removes entire table rows when the selected columns or selected region contains missing values.
• Users can output a cleaned copy as a new dataset or overwrite the current dataset after confirmation.

Import, Save, and Project Flow

• Import now makes the target explicit: current project or new project.
• Creating data in a new workspace now stays in the current project by default.
• Save behavior is clearer for single-project and multi-project workspaces.
• Saving all projects can produce a workspace that reopens the full set of projects.

Axis, Ticks, and Scale

• Added separate controls for figure title distance, X/Y axis title distance, and tick label distance.
• Added tick label rotation for clearer dense axes.
• Renamed minor tick control to "minor tick count" for a clearer mental model.
• Improved display of very small values such as 1e-12 so the axis does not collapse into zeros.
• Manual Y-axis display ranges now stay synchronized with display scaling and later range edits.

Composite Figures

• Added basic composite figure layouts: 1x2 and 2x1.
• Subplots remain independently selectable and editable.
• Users can adjust spacing, including negative spacing for close or partially overlapping panels.
• Shared X or Y axes are optional and off by default.

Curve Fills

• Added fill-to-baseline and fill-between-lines for line plots and connected scatter plots.
• Fill color, transparency, and gradient direction can be edited.
• Pure point-only scatter plots do not show curve fill controls, keeping the UI tied to meaningful geometry.

Scatter Trendlines

• Added a faster linear fitting entry from the series inspector.
• Supports current-series linear fitting, multi-Y linear fitting, and grouped fitting.
• Grouped fitting can combine selected groups into one overall trendline by default, or create one trendline per group when needed.
• Users can show or hide the equation and R-squared, and adjust fit line width and style.

SmartPlot Plus Updates

Plot Style Templates

• Added local Plot Style Templates from the Templates menu.
• Templates save visual styling such as typography, colors, line styles, axis styling, legend styling, canvas size, margins, and visual plot-type details.
• Templates do not save source data, data columns, automatic axis ranges, manual range values, or dataset-specific bindings.
• Templates persist locally across app restarts and normal app updates unless the user clears app data or moves devices.

Custom Shortcuts

• Plus users can edit shortcuts, detect conflicts, and restore defaults.
• Custom shortcut settings are saved locally on the machine.

Axis Breaks

• Added X and Y linear numeric axis breaks.
• Axis breaks support break start, break end, break width, and visual break style controls.
• Free users can see the Plus explanation and upgrade path; Plus users can enable and edit the feature.

Fit Confidence and Prediction Bands

• Added 95% confidence bands and 95% prediction bands for existing linear fit results.
• Band color and transparency can be edited.
• The V1.4 implementation focuses on linear fits first, leaving non-linear model interval bands for a later release.

Advanced Curve Fills

• Added split-color curve fills.
• Added crossing-aware fills between two curves.
• Added local X-range-limited fills.
• Area result output is intentionally deferred to avoid overlapping with the analysis integration workflow.

TIFF Export

• TIFF export remains a SmartPlot Plus feature for publication and submission workflows.
• Common exports such as PNG, SVG, PDF, and CSV remain part of the regular workflow.

Release and Update System

• Updated version metadata to 1.4.0 across the root package, desktop package, Tauri config, Cargo config, splash screen, and app UI.
• Added update source support through latest.json from the public SmartPlot downloads release.
• Added signed Tauri updater verification for update packages.
• Added update notification, update details, download/install progress, and relaunch handling.
• Note: the Windows installer is not Authenticode code-signed yet, so Windows SmartScreen may still show a warning. This is separate from Tauri updater package signature verification.

Website and Support Updates

• Updated the SmartPlot website for V1.4 positioning, templates, pricing, downloads, tutorials, support channels, SEO metadata, favicons, structured data, and analytics.
• Added QQ Channel, Discord, Xiaohongshu / REDnote, Facebook, Instagram, and email support links where appropriate.
• Added visual assets for website pages, tutorial promotion, and social/promo materials.

Known Limits and Follow-Up Items

• Composite figures currently support 1x2 and 2x1 layouts; 2x2 is intentionally deferred until the layout solver can keep panel sizing consistent.
• Axis breaks support linear numeric axes only; category axes and log axes are deferred.
• Confidence and prediction bands currently target linear fitting only.
• Clone templates and workflow templates are planned after the V1.4 Plot Style Template foundation.
• Windows Authenticode code signing is still recommended for future installer trust and SmartScreen behavior.
