plt is an alternative to MatLab's plot and plotyy routines for 2D applications. Like plot, plt commands can be typed at the command prompt to display your workspace arrays and can also be the core of your .m applications. Some of the advantages of plt are:

• Improved zooming, panning, and auto-scaling controls
• Workspace plotting (interactive selection of variables to plot)
• Automatically generated legend with powerful trace selection controls
• Up to 99 traces on a single axis (or more if a legend isn't needed)
• Support for dual y-axes (left/right linkable)
• Fast and easy cursor movement
• Delta cursor provides easy difference readout
• RMS, mean, and y/x ratio readouts
• Peak/Valley finder
• Better looking grid lines with selectable color
• User-entered annotations
• User editing of trace properties and figure colors
• Mouse and keyboard driven data modification
• Support for metric prefixes
• Quick linear/log toggling for x or y axes
• Display expansion history
• Flexible command-line interface
• Includes auxiliary functions and pseudo objects for building GUIs
• Extensive on-screen help with many example scripts.
