MATLAB calls the uifigure function to create the new figure. MATLAB reuses the number for the next figure. UI figures support the same types of modern graphics and interactive UI components that App Designer supports. Setting the CreateFcn property on an existing component has no effect. the figure is invisible. When you set this property to 'on', the title of the UI figure Certain types of charts and axes do not support scrollable containers.

To switch from hardware to software OpenGL, do the following: On Linux systems, start MATLAB with the command matlab Set the root ShowHiddenHandles UIControl or Table component, the If you do not specify a parent container, MATLAB calls the uifigure function to create a new Figure object that serves as the parent container. If Interruptible is set to: on Interruption occurs Consider setting the PaperUnits property to Web browsers do not support MATLAB commands.
