Thread Subject: Ploting String in a diagram

Hi
I have an excel file which I have imported to Matlab by xlsread.It has three column. One column includes only string data (In Matlab the class of these data is double), and other two columns are numbers. B and C will show the position of points in a diagram, and A are label of the points.
A= [Mt,Nt,Ot]
B=[1,2,3]
C=[10,25.5,30]
when I want to recall value of array A, ans is NaN.
what code should I use to read the element of column A, and plot them in diagram as a label for each point?
Thanks in advance

------------------------------------
Did you accept all three return values from xlsread()? Try that.
Once you have the strings, and position, you can use the text()
function to place the k'th label on your plot
text(A{k}, B(k), C(k));
or something like that.
