When I plot the model returned by the "fitlm" function, a legend is automatically added to the plot. I am creating multiple subplots, and would like to remove repetitive legends. How can I do this?

Below are two ways to remove a legend from a plot:

Use the "findobj" function to find the legend(s) and the "delete" function to delete them:
% Find and delete the legend
lgd = findobj('type', 'legend')
delete(lgd)
If you have multiple plots on the same figure (and thus multiple legends), the above will delete all of the legends for all of the plots. To only remove specific legends, you can delete the legend at a specific index:\n
delete(lgd(idx)) % where idx is the index of the legend(s) to delete
If you do not want to delete the legend, you can turn off the legend's visibility:
set(lgd(idx), 'visible', 'off')
