Welcome to the Digitizer wiki!

Below you can find a step by step instructions on how to use Digitizer.

• Add Digitizer repo to the MATLAB path.
• Type Digitizer on MATLAB command line.
• Here is how Digitizer GUI looks like when it loads for the first time.
• Left click File menu and select Load Image to load an image or screenshot of a data plot.
• Left click Choose Anchor Points and click on two different points on the image, preferably not aligned along horizontal and vertical dimensions (e.g., bottom left and upper right corners). Immediately after selecting two anchor points, enter corresponding X and Y coordinates on edit boxes under Coordinate System panel. Use check boxes to indicate that the axes, if any, are in log scale.
• Left-click Add Points and start selecting data points that belong a single series. Once done selecting points for a series, left click Add Points to disable data selection mode (If you want to change the name of the series, select the name of the series you wish to rename and left-click Edit).
• Left-click Add Series to add a new series, and repeat the previous step for adding new points.
• Left-click File menu and select Save Data to export data to a .mat file. The .mat file will have a separate variable for each data series. To save the series with a desired name, use the Edit button on the GUI.
• To remove data points, left-click Remove Points and select the rows you wish to remove in the table in the lower left corner of the GUI.
• To remove a data series, left-click Remove Series and select the series name from the list box in Data Manipulation panel.

I programmed this in a matter of hours and haven't fully checked against bugs/glitches. If you encounter any, please drop a message here.
