getdata graph s gud

If you have the full Adobe pdf, you should find a coordinate measurement system built into that. Memory is vague, but I think in the Navigation pane

i use getdata degitizer...nice one

You can use Datathief it is free, download it from the web

You can use surfer 8. Its an easy softwere and may be download free.

Another possibility is TerraGo

The following software programs are also good for this application:

1) Origin

2) ScanIt: https://www.amsterchem.com/scanit.html

3) WebPlotDigitizer: https://automeris.io/WebPlotDigitizer/
