What this add-on does

Anki Bar Graph displays your recent review activity as a bar graph directly on the Decks screen.

• No Statistics window
• Always visible
• Immediate feedback when you open Anki

By default, it shows your recent review history, helping you keep track of study momentum at a glance.

Core Features

• 📊 Bar graph shown directly on the Decks screen
• 📅 Displays review counts for a configurable recent period
• 🔄 Automatically updates after review sessions
• 🎯 Optional daily goal line
• 🖱 Hover to see exact review counts per day
• 🪶 Lightweight and fast (cached DB access)

🆕 Recent Updates (Latest Features)

📆 Configurable date range

You can now choose how many days to display:

• 7 days
• 30 days
• 90 days
• 180 days
• 365 days

This supports both short-term habit tracking and long-term trend analysis.

🎨 Full color customization (GUI color picker)

All colors can be configured via a color picker UI (no manual RGBA editing).

Customizable elements include:

• Past days bars
• Today’s bar
• Goal-achieved bars
• Goal line
• Background / border colors

🧩 Unified color setting components

All color options use a shared internal RGBA picker row, providing:

• Consistent UI behavior
• Easier maintenance
• Predictable previews across settings

🖱 Improved scroll behavior (UX fix)

Mouse wheel / trackpad scrolling is disabled on numeric and combo inputs to prevent:

• Accidental value changes while scrolling
• Unintended edits in the settings dialog

Applies to:

• Spin boxes
• Combo boxes

⚡ Safer configuration handling

• Invalid values (e.g. unsupported range days) are auto-corrected
• Unknown config keys are preserved during updates
• Reset to defaults reliably restores the original state

Configuration

Open:

Tools → Add-ons → Bar Graph → Config

Available options include:

• Enable / disable graph
• Display range (7–365 days)
• Daily review goal
• Bar width and spacing
• Chart height
