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.

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' Show all properties
% 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

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' Show all properties
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'} Location: 'none' Orientation: 'vertical' FontSize: 5 Position: [0.4500 0.3500 0.2567 0.1717] Units: 'normalized' Show all properties
