It will warn you if too many or too few pixels are detected. DataThief III is a program to reverse engineer data points from a graph. This function will then return the x and y coordinates of each data point. Then one pixel for each data point you wish to extract (default color: pure green). Do the same for the y-axis (default color: pure red). To use this tool, first annotate the plot by adding a single pixel at the start and end of the x-axis in a specified color that does not exist anywhere else in the image (default color: pure blue).
