Opens the Operations Dialog Here you can operate on data sets that means add or multiply the values of different graphs.
Opens the Average Dialog Here you can create a new graph from the averaged data of any other graph.
Opens the Smooth Dialog Here you can create a new graph from the smoothed data of any other graph.
Opens the Prune Dialog Here you can create a new graph from the pruned data of any other graph.
Opens the Histogram Dialog Here you can create a histogram of any graph. Choose the range and bins for the histogram in this dialog.
You need gsl installed to use this.
Opens the Interpolation Dialog Here you can interpolate any graph. You can choose the type of interpolation the range and the number of points for the resulting function in this dialog.
You need gsl installed to use this.
Opens the Differences Dialog Here you can create a graph of numerical differences for selected data (derivation of a function).
Opens the Integration Dialog Here you can numerical integrate the selected graph. Define the needed region or use the active region (can be defined under the appearance menu.)
You need gsl installed to use this.
Opens the Regression Dialog In this dialog you can make a regression of your data with different models and weight. The region can be defined here to.
You need gsl installed to use this.
Opens the FFT Dialog Here you can make a fast fourier transform of the selected graphs. If supported on your platform you can choose what library is actually used for the fourier transform (GNU scientific library (gsl) or the Fastest Fourier Transform in the West (fftw)). You can make forward or backward transform, make the x-Axis index, frequency or period and create the y-axis as magnitude, real, imaginary or phase.
You need gsl installed to use this.
Opens the Convolution Dialog In this dialog you can make a convolution/deconvolution of one graph with another. The used x-values can be selected.
You need gsl installed to use this.
Opens the Nonlinear Fit Dialog With this dialog you can make a nonlinear fit of your data. Currently 12 different models and any user defined model with up to 9 parameter can be selected. Start values, steps and tolerance for the non-linear least-square fit using gsl can be set.
You need gsl installed to use this.
Opens the Image Manipulation Dialog With this dialog you can manipulate matrix or image data as image. Operations like rotate, scale, sharpen or brighten can be performed here. Please see the analysis function overview.
