Visual Fitting is an editor to be able to represent mathematical data from a list of values that you indicate. It allows drawing both lines, as non-linear curves or non-linear surface models.
From Visual Fitting any binary function model can be represented. It has a practical data editor (very similar to Excel style sheets) to enter all values.
Each of the resulting graphics can be moved or rotated. Also, you can also zoom (both to enlarge and to dwarf) on certain areas of the chart. This graphic can be saved in BMP format.
You can free download Visual Fitting 32, 64 bit and safe install the latest trial or new full version for Windows 10 from the official site.
