Manual pick mode

To manually pick points in your graph of which you want to know the graph coordinates, you must make sure you are in Manual pick mode. You can select Manual pick mode from the Edit menu, or from the mode selection in the top left of the window.

You can only enter Manual pick mode if your axes have been defined.

Pick a point in your graph by clicking with the left mouse button. While your left mouse button is down, a symbol will occur. You can still move this symbol around until you let go of your mouse. Then, the symbol will be placed in the graph, and added to the current data set. This will show as the selected data point in the data list in the top of your screen.

Selected data points appear in another color than unselected data points (see options). As long as your data is visible, you can select and manipulate your data.

If Snap is turned on (in the top of the window, below the mode selection and window size, or press Ctrl+P), ScanIt will attempt to place the point on a curve or symbol near your selected location. To do this, it finds the nearest pixel that is not background color. Next, it tries to find the center of the curve or data point that pixel belongs to. If Snap fails, you will hear a beep and the point will be placed exactly at the location you clicked.

If Snap is turned off, the point will be placed exactly where you clicked. You can move the inserted point per pixel by using Ctrl plus the arrow keys on your keyboard.

The maximum distance Snap looks for is the scan window size. You can adjust the window size in the top left of the window, below the mode selector. The window size is in pixels of your image. If Snap is turned on, you can see the scan window as a box in the Zoom View.
