This plugin is a frontend to the pyeq2 2D/3D Data Fitting Python Library by James R. Phillips. When you start DWSIM and load a simulation, this plugin will be available on the Plugins menu. You'll also be able to send data directly from Sensitivity Analysis utility to this frontend, without the need to copy and paste.
