The Graph Digitizer takes graphs directly from the full-text and allows the user to digitize points on the curve by clicking on the graph. This allows the user to get a quicker, more accurate reading of X and Y data points than one would typically get by sight reading the graph. The Graph Digitizer is typically accessed directly, although there are often links to it through the full-text or an interactive table. The tool includes the basic functionality of saving and loading digitized graphs, printing, and exporting.
An offshoot of the Graph Digitizer is the Phase Diagram Viewer, which is specifically used when viewing phase diagrams for chemical compounds. The functionality of this tool is similar to the Graph Digitizer, as the user can still plot points on the graph to get a digital reading. An additional feature, called the Lever Rule, allows the user to set a horizontal line at a designated temperature, and then pick three points along the line. This function is useful to see how at a certain temperature, the phases of a compound changes as the composition changes.
The Phase Diagram Viewer, while useful as a scientific tool, is not likely a helpful tool to be used in prior art searching, rather to get a general idea of the properties of a composition at a given temperature.
