Hello, I am trying to plot this large dataset in Matlab. I am suppose to plot the all the points for my research project by incoperating 24 hour speeds for each day for a fifteen year period. I am new to Matlab and I'm not quite sure how to go about doing this.

You can use commands like textread() or textscan() to read data from a text file. I believe both of those can also read multiple files at once. These will bring the data into an array where you can analyze and organize it as you desire.

Try
str = fileread( 'dataset.txt' );
str = strrep( str, '''', '"' );
fmt = [repmat('%f',1,24),'%q'];
cac = textscan( str, fmt, 'Headerlines',2, 'CollectOutput',true );
%
figure, imagesc( permute( cac{1}, [2,1] ) ) % displays hourly values
ws = cac{1};
dv = mean( ws, 2 );
figure, plot( dv, '.' ) % displays daily values
What type of diagram do you want?
