How to reduce the size of legend in a fig file?

I have a MATLAB figure "abc.fig". The size of the legend is very large and has covered the graphs. I want to reduce its size and change its location. How can I do it? I applied the right click options but in vain.

This is your 70th question. By now you should be aware of the advice to attach relevant files and code. Why haven't you done that yet?

Thanks for your kind response dear Rik. The file is attached herewith.And the code is given below:

clear all
clc
x=[10 15 20 25 30 35 40];
y1=[0.48 0.31 0.2 0.16 0.15 0.14 0.14];%Purple
y2=[0.46 0.21 0.13 0.08 0.07 0.06 0.06];% Orange

You can try playing with the 'location' optional input, for example using

legend('blabla1','blabla2','Location','bestoutside')

Many options are available (check out this link)

Thanks dear Fabio Freschi for your kind response. That's ok. The actual issue is with the size of the legend area i.e., the area of the legend is so large that it has hidden the graphs. I want to make its size small so that the graphs are visible.Even if I move it outside, the whole graph becomes a line which is not desirable.

[Fabio Freschi]

Did you play with all options for the location? For example the

clear all, close all

x=[10 15 20 25 30 35 40];
y1=[0.48 0.31 0.2 0.16 0.15 0.14 0.14];%Purple
y2=[0.46 0.21 0.13 0.08 0.07 0.06 0.06];% Orange
y3=[0.42 0.19 0.14 0.08 0.07 0.06 0.06];% Yellow  
y4=[0.38 0.19 0.14 0.12 0.099 0.08 0.08];% Blue
y5=[0.3052 0.1660 0.0844 0.0629 0.0570 0.0365 0.019];% My graph
y6=[0.24 0.13 0.06 0.04 0.02 0.01 0.009];
Purple=[0.4940, 0.1840, 0.5560];

You have a lot of text in your legend. You shoud try to compress the expalnations.

If you really want to keep the current text, you can try to reduce the fontsize, even I don't recommend this option for legibility.

clear all
clc
x=[10 15 20 25 30 35 40];
y1=[0.48 0.31 0.2 0.16 0.15 0.14 0.14];%Purple

Thank you very much dear Fabio Freschi for your guiadance. Yes you are right that decreasing the font size seems bad. Your above code is very good. But since I reduce the size of the figure, so with that the legend area becomes large abd covers the graphs. With your code, the legend goes down and its very good but since I reduce the size of theb figure window so it seems very strnage to me.
