How to make size of legend window on a figure window as small as we desire?????

I have drawn my plot having a legend window on it. The legend is coming over the graph lines. I want to make size of the legend window as small as I want so that the graph is completely visible. How to do it? My figure is attached here.

[Simon Chan]

How about putting the legend outiside by setting the legend location?

openfig("fitness2snAll.fig");

figure
openfig("fitness2snAll.fig");
h = legend

h = 
  Legend (\bf Noise Free, \bf 35dB, \bf 45dB, 55dB, 65dB) with properties:

         String: {'\bf Noise Free'  '\bf 35dB'  '\bf 45dB'  '55dB'  '65dB'}
       Location: 'northeast'
    Orientation: 'vertical'
       FontSize: 9
       Position: [0.5254 0.6128 0.3500 0.2727]
          Units: 'normalized'

% Try to adjust the position of the legend
% But the pos may be modified by MATLAB
pos = h.Position;
pos(1:2) = [0.5 0.35];
pos(3:4) = 0.5*pos(3:4)

pos = 1×4

0.5000 0.3500 0.1750 0.1364

h.Position = pos

h = 
  Legend (\bf Noise Free, \bf 35dB, \bf 45dB, 55dB, 65dB) with properties:

Thank you very much for your help. But I have some problem in running the above code in my Matlab2016b. It gives the following error:

No public property NumColumns exists for class matlab.graphics.illustration.Legend.

Error in legendAdjust2 (line 4)

h.NumColumns = 3;

Further, I have asked in the question that how can we make size of the legend window as small as we want but you have displaed its position.

[Chunru]

Matlab2016b may not have the NumColumns property.

When you specify the Position property too small, MATLAB may automatically adjust the size. One way to make the legend smaller is to change the font size as shown below.

Displayce the position is to find the best position for legend to avoid the overlapping with other part of the figure.

figure
openfig("fitness2snAll.fig");
h = legend

h = 
  Legend (\bf Noise Free, \bf 35dB, \bf 45dB, 55dB, 65dB) with properties:

         String: {'\bf Noise Free'  '\bf 35dB'  '\bf 45dB'  '55dB'  '65dB'}
       Location: 'northeast'
    Orientation: 'vertical'
       FontSize: 9
       Position: [0.5254 0.6128 0.3500 0.2727]
          Units: 'normalized'

h.FontSize = 5;   % adjust this to meet your need
pos = h.Position;
pos(1:2) = [0.45 0.35];  % displacement
pos(3:4) = pos(3:4)      % size  (if too small, matlab will adjust it)

pos = 1×4

0.4500 0.3500 0.2567 0.1717

h.Position = pos

h = 
  Legend (\bf Noise Free, \bf 35dB, \bf 45dB, 55dB, 65dB) with properties:

         String: {'\bf Noise Free'  '\bf 35dB'  '\bf 45dB'  '55dB'  '65dB'}
