Fixed dragging behavior so all bars update when you drag: Problem: - Dragging a bar would change values but bars wouldn't visually update - The bar would reset to original length on release - Other bars wouldn't change at all Root cause: - We were converting the dragged value back to the selected unit - This kept the source unit the same, so relative percentages didn't change - The logarithmic scale maintained proportions, preventing visual updates Solution: - When dragging a bar, switch to that unit as the new source unit - Set both inputValue and selectedUnit to the dragged unit's value/name - This changes the conversion base, making all other bars recalculate - Removed draggedPercentage state (not needed with this approach) - All bars now use calculated percentages from conversions How it works now: - Drag the "feet" bar → becomes the source unit (selectedUnit = 'ft') - All conversions recalculate from feet - All bars update their percentages based on new conversion base - No transitions during drag for instant visual feedback - Smooth animation when drag ends 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>
