Occasionally, tabulated data is required where only graphical data is available. In such cases, obtaining tabulated data by hand can be time consuming. The C code described in this report provides a method for converting from graphical to tabulated data. It records mouse clicks to capture axis and graph information and then performs a transformation from screen coordinates to graph coordinates. The origin of the graph need not be present, and the axes can either be linear or logarithmic. Axes that are rotated andor skewed are accounted for.
