Graph Digitizer

Graph Digitizer is a tool that allows you to extract numerical coordinates from a 2D graph stored in a non-editable format such as an image. To use the program, first load the source graph. Then select two points on the horizontal axis and two points on the vertical axis. The program displays a dialog to specify the values on each axis and whether the axes are logarithmic or not.

Here are the detailed steps:

1. Open the Graph Digitizer program.

2. Click the "Load" button and select the graph you want to digitize.

3. Click the "Select Points" button and select two points on the horizontal axis and two points on the vertical axis.

4. Click the "OK" button.

5. The program displays a dialog to specify the values on each axis and whether the axes are logarithmic or not.

6. Click the "OK" button.

7. The program extracts the numerical coordinates from the graph and saves them in a text file.
