Toolbar

The toolbar for this app contains 5 buttons.

1. The first button is used to start the measurement on a 2D graph.
2. The second button is used to change the mode of line on the graph. There are 4 modes for the line to change. By default, it is "Move, Resize, Rotate" mode, which allows the line to be moved, resized and rotated. To change the mode, just click the second button, and the modes will be changed orderly from the default mode to "Move Only" mode, then to "Resize and Rotate Only" mode, then to "Freeze" mode, and then back to the default mode.
   • Move, Resize, Rotate: The measured line can be moved, resized, and rotated.
   • Move Only: The measured line can only be moved.
   • Resize and Rotate Only: The measured line can be resized or rotated, but not moved.
   • Freeze: The line is frozen.
3. The third button is like a toggle switch to show/hide the text displayed on the graph.
4. The fourth button is to terminate the app.
5. The last button is to open the help document.
