SUMMARY

The 'hold off' functionality from MATLAB is not available in Python's matplotlib library. Instead, users can manage plot elements directly using the remove() method on plot objects. The plt.hold() function is obsolete and will result in an error if called. To draw multiple traces on the same plot sequentially, one should utilize the remove() method on the current plot object to remove previous traces before adding new ones.

PREREQUISITES
  • Familiarity with Python programming
  • Basic understanding of matplotlib library
  • Knowledge of object-oriented programming concepts
  • Experience with plotting and data visualization
NEXT STEPS
  • Explore matplotlib's remove() method for managing plot elements
  • Learn about matplotlib's object-oriented API for advanced plotting techniques
  • Investigate the use of animations in matplotlib for dynamic visualizations
  • Review the official matplotlib documentation for best practices and examples
USEFUL FOR

Data scientists, Python developers, and anyone interested in creating dynamic visualizations using matplotlib.

In MATLAB one can 'hold off' to remove a previously drawn thing on the same graph. How about in python?

It would depend on the choice of plotting software accessed by python. A common one is matplotlib where it is possible. These examples may help:

Thanks very much. I want to draw 2 things in the same graph and show them 1 at a time (1st appears, 1st vanishes, 2nd appears...). I used plt.hold('off') but it was reported as an error.
 
When you are using a library like matplotlib you should refer to the API documentation provided by the developers. Using an IDE also helps as it will describe the arguments used by API methods.

Seems that hold(), obsolete, is no longer recognized.

Python:
from matplotlib import pyplot as plt
# Note the , in the next line: pyplot.plot returns a list and we
# want the first element which is a collection of 2DLines.
currentPlot, = plt.plot([1, 4, 9, 16])
# This will remove the collection of lines from the plot.
currentPlot.remove()
