GUI Plot Control

NRAO Home > CASA > CASA Cookbook and User Reference Manual

You can use the various buttons on the plotxy GUI to control its operation – in particular, to determine flagging and unflagging behaviors.

There is a standard row of buttons at the bottom. These include (left to right):

Home — The “house” button (1st on left) returns to the original zoom level.
Step — The left and right arrow buttons (2nd and 3rd from left) step through the zoom settings you’ve visited.
Pan — The “four-arrow button” (4th from left) lets you pan in zoomed plot.
Zoom — The most useful is the “magnifying glass” (5th from the left) which lets you draw a box and zoom in on the plot.
Panels — The “window-thingy” button (second from right) brings up a menu to adjust the panel placement in the plot.
Save – The “disk” button (last on right) saves a .png copy of the plot to a generically named file on disk.

In a row above these, there are a set of other buttons (left to right):

Mark Region — If depressed lets you draw rectangles to mark points in the panels. This is done by left-clicking and dragging the mouse. You can Mark multiple boxes before doing something. Clicking the button again will un-depress it and forget the regions. ESC will remove the last region marked.
Flag — Click this to Flag the points in a marked region.
Unflag — Click this to Unflag any flagged point that would be in that region (even if invisible).
Locate — Print out some information to the logger on points in the marked regions.
Next — Step to the next plot in an iteration.
Quit — Exit plotcal, clear the window and detach from the MS.

These buttons are shared with the plotcal tool.
