Graphics and 3-D Visualization, MATLAB Version 7.9 (R2009b)

New features and changes introduced in this version are:

• Enhanced Plot Selector Simplifies Data Display

• Certain Print Options and Devices Now Warn When Used

• The view Function No Longer Supports 4-by-4 Transformation Matrices as Input

Enhanced Plot Selector Simplifies Data Display

The Plot Selector workspace tool creates graphs of workspace variables. As this video demo shows, the tool lets you access more types of data display functions and provides help about each one. It also categorizes display functions and lets you organize them within its drop-down menu. The following illustration shows the old and new versions of the Plot Selector and calls out new features.

Use the Plot Selector tool to instantly generate graphs of workspace variables. You can choose from more than 40 two-dimensional, three-dimensional, and volumetric MATLAB data display types. It also constructs graphs using Control System Toolbox™, Financial Toolbox™, and Statistics Toolbox™ functions if your installation includes those products.

The Plot Selector button displays a graph icon and the names of selected variables in the Workspace browser or the Variable Editor. Until you select one or more variables, the button reads Select to plot . The graphing function for one or two data vectors still defaults to plot, but the tool now gives you additional options and information, including the following:

• The grouping of menu items into categories of graph types, such as Stem and Stair Plots, 3-D Surface Plots, and Analytic Plots. You can rearrange categories and items within a category by dragging them.

• A Favorites category at the top of the menu, where you can collect the types of graphs you use most often. Your collection of favorites persists across MATLAB sessions.

• A star-shaped button on menu items that adds a graph type to or removes one from your Favorites collection.

• Two tabs for toggling the scope of the menu:

  • Plots for <variable names> — The set of graphs you can generate with the currently selected variables

  • All plots — A master list of graphing functions available on your system

  On the All plots tab, graphing functions that are not compatible with the selected variables display in gray and do not plot. Incompatible plot types do not appear on the first-tab menu.

• A button to interchange the axes positions of two selected variables

• Pop-up descriptions of function syntax when your mouse pointer lingers over a menu item

• Direct access to your Favorites from context menus in the Workspace Browser and the Variable Editor

For more information, see Creating Plots from the Workspace Browser.

Compatibility Considerations

• In previous versions, the Plot Selector automatically assigned variables named t and time to the x-axis. Now, the variable you select first always plots on the x- axis. Use the switch variable input order button to interchange the x and y variables before plotting them.

• In previous versions, clicking Plot Selector > More Plots opened the Plot Catalog tool. Now, you click Catalog at the bottom of the Plot Selector GUI to open the Plot Catalog tool. The Plot Catalog has not changed.

Certain Print Options and Devices Now Warn When Used

The following print command option and device now throw warnings when used and will be removed in a future release:

Option/ Device	Warning ID	Warning Text
'-adobecset' print option	'MATLAB:print: adobecset:DeprecatedOption'	The -adobecset option will be removed in a future release.
'-dill' print device (native support for Adobe Illustrator)	'MATLAB:print: Illustrator:DeprecatedDevice'	The '-dill' print device will be removed in a future release. Use Encapsulated PostScript ('-depsc') instead.

If you wish to prevent these warnings from displaying, use the warning command.

• To disable the warning generated by using the –adobecset print option:

  warning('off', 'MATLAB:print:adobecset:DeprecatedOption');

• To disable the warning generated by using the –dill print device:

  warning('off', 'MATLAB:print:Illustrator:DeprecatedDevice');
  

Compatibility Considerations

If you have developed code that uses the previous option or device, in the future you must remove such calls or replace them with other code.

The view Function No Longer Supports 4-by-4 Transformation Matrices as Input

The view function. no longer supports 4-by-4 transformation matrices as input arguments. Previously, you could create a 4-by-4 transformation matrix and use it with view.

Compatibility Considerations

If you have code that calls view(T), explore using view([az el]) instead.
