The Analysis Menu

Analysis -> Statistics on Columns

Creates a new table providing basig statistical information about the selected columns in the active table: average, variance, standard deviation, max value, etc...

Analysis -> Statistics on Rows

Creates a new table providing basig statistical information about the selected rows in the active table: average, variance, standard deviation, max value, etc...

The following items are enabled only if the active window is a 2D Multilayer Plot Window. If the active plot layer contains more than one curve, and the Data Range Selectors are not enabled, a dialog window will pop-out allowing you to select the curve you want to analyse.

In most of the cases (except for integration), a new red curve is added to the active plot layer and a a new table containing the data used to plot this curve is added to the workspace. Useful information about the operation performed will be showed in the Results Log display.

Analysis -> Integrate

Opens the Integration dialog, allowing you to choose the curve to integrate and the integration method.

Analysis -> Interpolate ->
Linear

Performs a linear interpolation. The curve you analyse must contain at least 3 points, if not a warning message will be prompted out.

Cubic Spline

Performs a cubic interpolation. The curve you analyse must contain at least 4 points, if not a warning message will be prompted out.

Non-rounded Akime spline

Performs a Non-rounded Akime interpolation. The curve you analyse must contain at least 5 points, if not a warning message will be prompted out.

Analysis -> FFT ->
Forward

Performs a forward FFT transform of the selected curve.

Inverse

Performs an inverse FFT transform of the selected curve. The inverse FFT transform of a forward transform will result in a data set identical to that used for the forward transform.

Analysis -> Differentiate

Creates a new plot displaying the resulting curve of the numerical differentiation.

Analysis -> Fit Linear

Performs a linear fit of the selected curve.

Analysis -> Fit Polynomial...

Opens the Polynomial Fit dialog, allowing you to choose the curve to fit, the order of the polynomial function to use, the number of points of the resulting curve and the abscissae limits for the fit.

Analysis -> Fit Exponential Decay ->
First Order

Opens the Exponential Fit dialog, allowing you to choose the curve to fit and the initial guesses for the fit parameters.

Second Order

Opens a dialog, allowing you to choose the curve to fit and the initial guesses for the fit parameters.

Third Order

Opens a dialog, allowing you to choose the curve to fit and the initial guesses for the fit parameters.

Analysis -> Fit Exponential Growth

Performs an exponential growth fit of the selected curve.

Analysis -> Fit Gaussian

Performs a gaussian fit of the selected curve.

Analysis -> Fit Lorentzian

Performs a lorentzian fit of the selected curve.

Analysis -> Non-linear Curve Fit... (Ctrl+Y)

Opens the Non-linear Fit dialog, allowing you to choose the curve to fit, the algorithm and the tolerance, the number of iterations to be performed, and to type the analytical function to use, the names of the fitting parameters and their initial guessed values.
