I understand that

set(gca, 'FontSize', 6.0);

will set the default size of a plot. But I have let me say 10 plots in this Livescript. Is there any way to set the default size of a plot so that one does not need to do this for each plot?

This is not documented appropriately. Since FontSize is a text object property (my experience with MATLAB here), use:

DefaultFontSize = get(groot, 'defaultTextFontSize')

to get it, and a set call to change it.

Example —

DefaultFontSize = get(groot, 'defaultTextFontSize')         % Original Value
set(groot, 'defaultTextFontSize', 6)                        % Set To New Value
DefaultFontSize = get(groot, 'defaultTextFontSize')         % Check For New Setting

Run that to get the original value, then change it, and see the result.

I tested this with this code:

hold on
text(0.5, 0.5, 'Text')
DefaultFontSize = get(groot, 'defaultTextFontSize')         % Original Value
set(groot, 'defaultTextFontSize', 6)                        % Set To New Value
DefaultFontSize = get(groot, 'defaultTextFontSize')         % Check For New Setting
text(0.5, 0.6, 'Text')
set(groot, 'defaultTextFontSize', 10)                       % Reset TO Original Value
DefaultFontSize = get(groot, 'defaultTextFontSize')         % Check For New Setting
text(0.5, 0.7, 'Text')
hold off

and it works.

MathWorks — It would be nice to have all this in one central documentation section.
