Turn a picture of a graph back into numbers, the way g3data does.
Values come from a full two-vector calibration: the X value is read along the X1→X2 line and the Y value along the Y1→Y2 line, so the axes need not be perpendicular or level. On a log axis the interpolation runs in log₁₀ space. The optional dx and dy columns propagate the click uncertainty (half an image pixel by default) through the calibration. Projects save the image, axes and every series in one .json file you can reopen later.
