In one short list, the difference between CurveExpert Pro and GraphExpert Pro is:

  • CurveExpert Proone dataset at a time, heavy-duty nonlinear regression analysis and smoothing.  Facilities for searching for the best nonlinear regression fit.  Focused on the data analysis, with the graphing present for visual verification of the result.
  • GraphExpert Pro: multiple datasets at a time; a greater breadth of analysis but more lightweight; only linear regression (as well as ANOVA, moving average, FFT, etc.); no nonlinear regression supported yet.  Focused on data management and visualization.
