5. Plotting Your Data

Two of the main design goals of ATHENA are to make basic data processing, i.e. background removal and Fourier transforms, as transparent as possible and to make processing of large amounts of data as seamless as processing a single data group. To this end, there are no buttons or other kinds of controls that explicitly tell ATHENA to perform the basic processing chores. Instead, there are the plot buttons. When you click one of the plot buttons, the data processing which is required will be performed before the plot is made. For example, if you press the R button, the background will be removed from the current group and the χ(k) will be Fourier transformed to χ(R). Once all that is finished, the plot in R-space will be made.

As you change the values of the parameters in the main window, ATHENA keeps track of what has been changed and which data processing steps need to be redone. If you change the «krange» parameters, then press the R button again, the Fourier transform will be updated, but ATHENA will recognize that the background removal is still up-to-date.

Plotting the current group

The row of orange buttons are used to plot the current group. The current group is the one highlighted in the group list and the one whose parameter values are displayed in the main window. The controls used to determine how the plots are displayed are described in the next section.

  1. Clicking leftclick the E button brings the background removal up to date and plots the μ(E) data
  2. Clicking leftclick the k button brings the background removal up to date and plots the χ(k) data
  3. Clicking leftclick the R button brings the background removal and Fourier transform up to date and plots the χ(R) data
  4. Clicking leftclick the q button brings the background removal, Fourier transform, and backwards transform up to date and plots the χ(q) data
  5. Clicking leftclick the kq button brings the background removal, Fourier transform, and backwards transform up to date and plots the χ(k) data along with the real part of the χ(q) data

Plotting many groups

The row of purple buttons are used to plot the set of marked groups. The marked groups are the ones with their purple button checked in the group list. More details about the marking groups are found elsewhere in this document. The controls used to determine how the plots are displayed are described in the next section.

  1. Clicking leftclick the E button brings the background removal up to date for all marked groups and plots their μ(E) data
  2. Clicking leftclick the k button brings the background removal up to date for all marked groups and plots their χ(k) data
  3. Clicking leftclick the R button brings the background removal and Fourier transform up to date for all marked groups and plots their χ(R) data
  4. Clicking leftclick the q button brings the background removal, Fourier transform, and backwards transform up to date for all marked groups and plots their χ(q) data

Right clicking on plot buttons

Several of the plot buttons will respond to a right click by making one of the special plots from the Plot menu.

  • Right click rightclick the E button: plot μ(E) with I0 and the signal
  • Right click rightclick the k button: display the k123 plot
  • Right click rightclick the R button: display the R123 plot
  • Right click rightclick the kq button: display the quad plot
  • Right click rightclick the E button: plot I0 for each marked group
  • Right click rightclick the q button: display the bi-quad plot

All other plot keys respond to a right-click rightclick in the same way as a left-click leftclick.

The responses of the E button and the E button can be configured with the ♦Athena→right_single_e and ♦Athena→right_marked_e configuration parameters.
