Graphs are great for understanding results in , but to use those results in your own analysis, you'll want the underlying numerical data. Your analysis will be more flexible because you can easily include all the data from the graph, rather than just a few points read manually.
Dagra can import most common image formats (BMP, GIF, JPG, JPEG, PNG, TIFF, WMF, EMF). You can also use an image from the clipboard (copy a graph directory from a Acrobat PDF file, for example), or grab a screen shot.
Digitize scatter plots or quickly trace smooth curves with Dagra. Tracing curves is fast because you do not have to tediously locate every data point. Instead, Dagra uses Bezier curves that let you quickly fit a smooth, accurate line through any curve using only a few control points.
Dagra uses interpolation to find all the points on the curve it needs to accurately describe your data.
