This sample shows how to apply model to find curve fit.

  1. Select data series on left panel [Points].
  2. Select menu item <Fit><Fit Function>.
  3. The 'Approximation line' Wizard appears.
  4. On step 2 select item 'User defined function'.
  5. On step 3 select in the list the function
    f(U) = V0 + (U-U0)^M *(A0+...+AN*U^N).
  6. On step 4 click Recalc.
  7. New graph will appears. See how curve fit conforms your data.
  8. On step 3 vary the parameters N and M and click Recalc again to get best fit.
  9. On step 5 select line color and click Add Line.
