You can reorder points, change increments, and delete "junk" data captured from grid lines. Why use version 2.24?
The calibration phase is arguably the most critical. The user imports an image file (such as a BMP, JPG, or TIFF) and sets the coordinate system. By clicking on specific points on the axes—typically the origin, the maximum X value, and the maximum Y value—the user teaches the software the scale of the graph. This feature allows the software to handle linear, logarithmic, and even non-orthogonal (skewed) axes, correcting for distortions that might occur during scanning or photography. getdata graph digitizer 2.24

For typical scientific graphs, users report accuracy within of original values when careful. For high-stakes work, digitize the same curve two or three times and average the results. The user imports an image file (such as
If you are digitizing published graphs, remember to cite the original source and the fact that you used digitization software. Example acknowledgment: “Data extracted from Figure 3 in Smith et al. (2008) using GetData Graph Digitizer version 2.24.”
