Matrix of date and number to plot

I have a array matrix of only 2 columns: 1st col is all date (datenum), 2nd col is all number. If I would like to plot a graph that y-axis is number and x-axis is datestring like (03-Mar-2011), should I convert the array matrix to cell matrix? and convert the datenum to string by datedisp?

It's simpler just to leave the data as it is and use datetick to set the axis annotations on your graph. Like this:

plot(data(:,1), data(:,2));
datetick('x', 'dd-mmm-yyyy');
