Plotting an imported value vs time

Hello,

I am interested in plotting a numerical value verse time. I have also attached the file I am trying to read. Here is the code I have generated so far:

fid=fopen('Sensor 1.txt');
fmt = ('%s%s%*s%*s%*s%f%*s%*s');
data = textscan(fid,fmt,'headerlines',39,'collectoutput', true,'delimiter',';');
phase = data(:,2);
dn = datenum([char(data{1,1}(:,1)) char(data{1,1}(:,2))],'mm/dd/yyyyHH:MM:SS AM');
fid=fclose(fid);
plot(dn,phase)

I am receiving the error message: Error using plot Conversion to double from cell is not possible.

Error in date (line 7) plot(dn,phase)

Any help would be greatly appreciated!

Change the phase assignment to:

phase = cell2mat(data(:,2));

and it works.
