delete plot annotation

Description

Since the textboxes are children of groot is is difficult to delete them

Algorithm (Workflow)

This function, plotannotationdelete, is designed to delete textboxes from a MATLAB plot. It is part of the SolidGeometry library and was introduced in version 5.0. The function operates by identifying and removing textboxes that are children of the root graphics object, groot.

Input Parameters

The function does not take any input parameters.

Output

Algorithm Steps

  1. Use the findall function with groot to locate all graphics objects in the current MATLAB session.
  2. Filter these objects to find those of type 'Textbox' using the findobj function.
  3. Store the handles of these textboxes in the variable h.
  4. Delete the textboxes using the delete function, passing h as the argument.

Example Usage

The function can be used in a sequence of plotting commands to remove annotations after they have been displayed:

plotannotationtopleft('A');
plotannotation('B');
shg;
pause;
plotannotationdelete;

This example demonstrates creating annotations 'A' and 'B', displaying the plot, pausing for user interaction, and then deleting the annotations.
