Hello,

Every time I open a saved figure, it appears not as I had saved it, but with the default configurations of MatLab. To get around this, I use the command

set(0,'defaultAxesFontSize',25, ...
    'defaultAxesTitleFontSizeMultiplier', 24/25)

This command makes de default axes font size to be 25 and the title font, to be 24. Nevertheless, I could not use the same command for the marker size in the legend. In other words, I couldn't find a command of the type

set(0,'defaultMarkerSize',10)

Is there a command that does this? (Another welcome solution would be a way to open the saved figures with the original configurations I choosed to them.)

As an example, I've made the following simple program:

x = randn(1,1000);
y = randn(1,1000);
figure, plot(x,y, '.')
legend('randn')
[h,icons] = legend('randn');
icons(3).MarkerSize = 15; % This line makes the marker size of the legend bigger

The result is as follows from the figure (a). When I save and then reopen this figure, however, the marker size of the legend comes back to be the smaller size (equal to the size of the points in the graphic). Figure (b) shows this event. Is there a way to set a default marker size in the legend so this wouldn't happen?

Thanks

ps: I am using MatLab 2018a

I asked this question because, on the figures I'm currently working with, the default size of the markers in the legend is very small. An example is shown below.

To change the marker size of the legend you can simply do

set(icons(3), 'Markersize', 12); %set marker size as desired

Pankhuri,

Thanks for your answer. I know how to change the size of the marker in the legend. I did this in this line shown above:

icons(3).MarkerSize = 15;

The thing is that I want to change the default value of the legend marker size. Because everytime I open a saved figure, it appears with the MatLab default configurations, not the ones I've saved the figure with.

It is very annoying to change by hand the legend marker size every time I open a figure. This is why I want a default configuration of the legend marker size or a way to open the figure with the configurations I've saved to it.
