I have a two-column data set that I would like to plot. The data I would like to plot on the x-axis is datetime in the format yyyy-MM-dd refer to attached picture). What to I need to do to be able to plot the dates? I have not been able to find how to change them all into the correct format altogether, is this possible?

You may specify the format of the time axis in the plot command. See the documentation of plot()

%%  Create some data that resambles your image
vec = zeros( 14, 3 );
vec(:,1) = 2010;
vec(:,2) = 1;
vec(:,3) = reshape([1:14],[],1);
y = randi([30,36],14,1);
DT = datetime( vec );
%%
lh = plot( DT, y, 'd', 'DatetimeTickFormat','yyyy-MM-dd' );
