3.3.1.16 Iteration

In many cases, it is desirable to iterate through the data that were selected in the Data tab. A typical example is to display a single baseline in a time vs. amplitude plot and then proceed to the next baselines step by step. This can be done via the Iter tab on the left hand side of plotms. A drop-down menu allows you to select the parameter to be iterated on, such as baseline or spw (press plot after changing your selection). The plot titles in the main panel in plotms show which data slice is currently displayed. To proceed to the next plot use the green buttons below the main panel. The different button symbols let you to proceed panel by panel or to jump to the first or last panel directly.

There are two scaling options for the axes: Global and Self. Global will use a common axis range based on data loaded with the selection criteria specified in the Data tab. Self readjusts the axes scaling to the data for each individual panel of the iteration.

Note that exporting iterated data only refers to the shown panel, the exported files do not (yet) collate all the iteration panels in say a multi-page pdf. So please export every panel separately.

The Rows and Columns selection boxes will, in the future, control the number of panels for multi-panel plots. This feature is likely available in CASA 3.3 and higher.
