Data Input

WindRose supports manual data entry and CSV uploads for easy data management.

Manual Entry

Click any cell in the data table to edit values directly. Each cell holds the frequency or count of observations for that direction and speed bin. The values represent how often wind comes from that direction at that speed range. The Total column shows the sum for each direction.

The table includes:

8 direction rows (N, NE, E, SE, S, SW, W, NW)
Speed bin columns (configurable - see Configuring Bins)
Auto-save - changes are stored in your browser automatically
Undo/Redo - Use Cmd/Ctrl+Z and Cmd/Ctrl+Shift+Z or toolbar buttons

Keyboard Shortcuts

Tab / Shift+Tab - Move horizontally between cells
Enter / Shift+Enter - Move vertically between cells
Arrow keys - Navigate between cells
Escape - Cancel edit and revert to original value
Cmd/Ctrl+C - Copy cell value
Cmd/Ctrl+V - Paste (supports multi-cell ranges from spreadsheets)
Cmd/Ctrl+Z - Undo
Cmd/Ctrl+Shift+Z (or Ctrl+Y on Windows) - Redo
