Grab It!

Grab It! is a Microsoft Excel based application that digitizes data from pictures. Graphs and charts can have data point values digitized or have angle and distance measurements made on scanned photos. Skewed graphs are handled automatically (sometimes scanning isn't perfectly straight) as well as linear, log, date or time charts. Output is displayed in real time and special features for error bar graphs, stock charts, and multiple data sets are included. This is especially useful for accurately digitizing published data in open literature for comparison against your own data or improving accuracy when digitizing old data that isn't in an electronic format (old hardcopies of charts for instance).
