3.3.1.15 The Options Tab

A few miscellaneous options are available in the Options tab, the last tab at the top of the plotms window. The Tool Button Style drop-drop down menu determines if icons and/or text represent the buttons in the toolbar near the bottom of the plotms window.

The Log Events drop down menu determines how verbose plotms is in documenting its actions on the command line.

There is a checkbox that determines the persistence of regions and annotations on new plots, labelled When changing plot axes, clear any existing regions and annotations.

A useful option is the fixed size for cached image checkbox. It determines how large the dots in the panel are with respect to the screen resolution. The values influence how the data is redrawn on the panel. When the Screen resolution is selected, the plotms window can be resized without redrawing on the canvas – a considerable speedup for large data sets. The penalty is that the dots of the data points are the size of a pixel on the screen, which may be very small for high resolution monitors.

Finally, the File chooser history limit determines the number of remembered directories in the file loading pop-up of the Browse selection of the Data tab.
