I don't see an RPM, but the installation is pretty simple: export PATH=/path/to/your/java/bin:$PATH sh PlotDigitizer_2.4.1_Linux_installer.bin It will open an installer. I install in /home/kwan/bin/Plot_Digitizer and create links in /home/kwan/bin. Accept the rest of the defaults... Run the Plot_Digitizer, open your image file, then follow the tabs to grab data. Here's an example of the output: -9.27083 -0.21364 -9.13194 -0.37273 -8.92361 -0.54091 -8.71528 -0.69091 -8.54167 -0.80000 -8.33333 -0.88636 -8.09028 -0.98182 -7.88194 -1.00000 -7.39583 -0.89545 -7.15278 -0.75455 -6.94444 -0.58182 -6.73611 -0.44545 -6.63194 -0.31364 -6.45833 -0.19545 I used gnuplot to create a sin(x) plot then saved the plot as a PNG. I then used Plot_Digitizer to extract the data.. There's obviously some noise, but if your scale is better your results should improve. -- users mailing list users@lists.fedoraproject.org To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines
