Measurements#

WebPlotDigitizer offers several measurement tools for analyzing images and plots. Here's a summary of the available measurement tools:

1. Distance Measurement:

   • Allows measuring distances between points on an image.
   • For Map axes, distances are converted to the units specified during calibration.
   • For other plot types, distances are reported in pixels of the original image.

2. Angle Measurement:

   • Enables measuring angles between points on an image.
   • Angle measurements are independent of any axes calibration.

3. Area and Perimeter Measurement:

   • Allows drawing polygons to measure the enclosed area and perimeter.
   • For Map axes, area and perimeter are converted to the units specified during calibration.

Common features for measurements:

• Add measurements using the "Add" button or by pressing the 'A' key.
• Adjust measurement points using cursor keys (use Shift for faster movement).
• Delete individual measurements with the "Delete" button or 'D' key.
• Clear all measurements in a specific mode using "Clear All".
• View and export measurement data to Plotly or CSV format using "View Data".
