| plotlabels |
Adds the specified title and axis label strings to the current plot and links each string object to the editing function
'textedit.m' |
| plotmenu |
Adds a menu item to a MATLAB figure containing commands for exporting figures in various vector and bitmap formats, toggling axis gridlines, and generating serial date plots are various intervals as images with or without accompanying HTML pages and thumbnail previews. |
| plotwidgets |
