1.3.2 Tiled plots

 

1.3.2.1 How to plot in a tiled window

The memory buffer window  (Sec.1.3) contains a Tile button. Selecting one or more spectrograms in that window and clicking the Tile button generates a tiled plot of all selected spectrograms. The plot is drawn on a separate window, thus the main Specview window remains available for other uses.

 

 

 

 

Each spectrogram plot is identified by a sequential number that corresponds to the sequential numbers displayed in the memory buffer window.

The usual mouse click commands available in the main Specview window are also available on each individual plot (Sec. 2.4, “Cursor commands”). Thus one can use a mouse left click to display the spectrogram identifier, or a mouse right click to access the spectrogram properties, such as header, metadata and tabular data.

 

1.3.2.2 Configuring the tiled window to user preferences

The tiled window menu bar has a Preferences menu. This menu gives access to three user-configurable parameters:

 

  • Mode: the Mode menu enables the selection between two tiling modes: Fixed aspect ratio, and Fit window. Fixed aspect ratio mode will cause the individual plots to conserve aspect ratio when the window is resized; scroll bars will appear if necessary so all plots can be accessed by scrolling. In Fit window mode, all individual plots will be squeezed to fit into the current window, with no scroll bars.
  • Tiles per row: selects the number of tiles per row. The number of rows will be dynamically set to encompass the entire list of selected spectrograms.
  • Aspect ratio: enables the selection of a specific aspect ratio; only active when Mode is set to Fixed aspect.

 

These user preferences can also be set via a Preferences Editor (Sec. 9).

 

Bug: scroll bars can be occasionally painted over by the plot graphics.
