It is a free and open-source tool. You can find it on Github. You can extract data from XY, ternary, polar, and maps. However, it has many faults and drawbacks. The software is not well-maintained, and it is very buggy and cannot handle heavy operations. If you use it often, you will notice many errors. There are also some major glitches with the user-interface. >> downloaded, but I can't see how to launch!?!?!? Though the program is free, it comes with many bugs. PlotDigitizer is the best alternative to WebPlotDigitizer; it totally outclasses WebPlotDigitizer. PlotDigitizer has far more features; it is polished and well-maintained and has a professional touch. You can try PlotDigitizer’s free online app. In this short guide, we will compare the features of both. >> free online app 08********08 #] 26Jan2021 Digitizelt lessons - from David Fischer medieval to modern pricing mini-project gimp - must provide [continuous, unbroken, same-color] curves!! make curve continuous Menu -> Tools -> Paint -> pencil adjust line width = 3 (see gimp instructions in d_SysMaint) but basically [Alt, mouse wheel] to [thicken, thin] Menu -> Tools -> Paint -> pick color -click on existing curve to match color (somewhat) generate path by clicking change points of curve where it is been [augmented, continuous] Menu -> Edit - "stroke path" clean up curve!!!
