GraphData is designed to automatically extract numeric data from charts (bmp, gif, jpg, etc.), facilitating the work of extraction the numbers and increasing its accuracy.
The program finds the graph's line through its color, to be specified by the user in advance. Therefore can not appear in the image other graphics or text that have the same color as the chart's line. Also for this reason it is possible to extract data from different graphics on the same image as long as the color of each line is different.
