This can cause frustration, particularly if you rely on the stability of your plot settings. In this guide, we will delve into the issue and explore a proven solution that allows you to maintain your default settings while still using hold statements effectively. Understanding the Problem The Core Issue You set the default FigureNextplot property to 'new', which is atypical since the factory setting is 'add'. When you execute the command hold on, MATLAB naturally changes the FigureNextplot and AxesNextplot properties to 'add' as expected. However, upon executing hold off, while the AxesNextplot property resets appropriately, the FigureNextplot property remains altered. This can lead to confusion and unexpected behavior in your plots. The Key Question You might be wondering: Why does hold off restore the AxesNextplot property but not the FigureNextplot property? And how can I keep my default settings intact without having to remove hold statements from my code? The Solution: A Custom Hold Function To tackle this problem, there’s a simple workaround that allows you to retain the FigureNextplot property setting while utilizing the hold function effectively. This can be achieved through the creation of a user-defined hold function. Here’s how to do it: Step-by-Step Process Create a Custom Function: Save the following user-defined function code into a file named hold.m: [[See Video to Reveal this Text or Code Snippet]] Add Your Function to MATLAB Path: Place the hold.m file in a user-defined folder, and add this folder to your MATLAB path using the command: [[See Video to Reveal this Text or Code Snippet]] Utilizing the Custom Hold Function: Now, whenever you call hold in your code, it will execute this function, ensuring that the FigureNextplot property is restored to its original setting after using hold on or hold off. Important Notes to Consider Toggle Behavior: Be aware that calling hold without arguments toggles the hold state. MATLAB internally considers the states of both the Figure and Axes properties to determine whether to maintain the previous settings. Thus, if the FigureNextplot property is set to 'new', the hold state will be recognized as off, preventing unintended plot preservation. Conclusion Understanding how hold off interacts with the FigureNextplot property can be crucial for maintaining a stable plotting environment in MATLAB. By implementing a user-defined function, you can effectively manage this property according to your default settings. Now go ahead, try out this solution, and streamline your MATLAB plotting workflow!
