Quick Start:

  1. Scan your graph and save it in a supported image format (e.g. gif, tiff, png, bmp...), or copy it into the clipboard.

  2. Load the graph into DigitizeIt: File->Open or paste a graph via the clipboard (Edit->Paste Graph). You can also take a screenshot (Edit->Capture Screenshot).
    Tip: scan your graph at a reasonable resolution, 1000 x 1000 pixels is usually enough

  3. Zoom the graph to your liking with View->Zoom in

  4. Put the axes:
    a) select Axis->X min
    b) now click on the lower value of the x-axis
    c) enter corresponding x-axis value
    repeat this for X max, Y min, Y max

  5. Select linear, logarithmic or reciprocal scaling: Axis->x Scale->logarithmic

  6. Now you are ready to go, after Data->Take points start selecting points by clicking on the screen.
    You can also let DigitizeIt automatically digitize line or scatter plots for you. Select Auto->Find Line or Auto->Find Symbol and click on the desired line or one of the symbols, see also line digitizing and symbol digitizing.

  7. Choose, if you want the data sorted Data Set->Sort

  8. The rest should be self-explanatory, when you are done save the data in ASCII-format with File->Export ASCII or copy the data to the clipboard (Edit->Copy to Clipboard). Now the data can be pasted or loaded in many other applications.

  9. You can save the complete workspace for later use with File->Save Project.
