Tablelizer for Mac

Tablelizer ... Sometimes, you have the image or printout of a diagram, but lack the original Excelfile. Tablelizer helps to extract data from these images. First, you have to measure the Chart, and set the origin and reference-sizes. If Y-Axis ranges from 0 to 10, then reference is a 10. If X-Axis ranges from 0 to 70, reference is 70 accordingly. Now, you are ready to fetch the data. Just click the top-edge of the chart-entries. After setting the points, you can export the table into a CSV-file to use it e.g. in Excel or OpenOffice.
