JTextField data reading problem

Question

Hello,
I am attempting to construct a gui in which I parse data from a file into 3 different arrays, one is pure numbers the other two are strings of variables describing the data for a specific index of the data in the first array.
I pass the raw data (all the numbers) to a plotting function, which plots 3 graphs at a time and is placed in a JLayeredPane. Over the plot I have a bar (place marker) with an associated mouselistener which calculates which index of the raw data array the bar is over as the bar is dragged over the plot.
Beside the plots are two Jpanels that contain the data of the other two arrays. I only want to show the variable name and the data associated with index that is calculated from the bar/mouselistener described above.
I designed this using JTextFields. I did not want to use JTable, because I only want to show the one column of data at a time.
My problem is when I try to create an array of JTextFields, only a small portion of the data is passed. I want to use to 80 variables, but will only accept 12.
for(int m=0;m<dvnum+1;m++){
     System.out.println("diagvar["+m+"][0]= "+diagvar[m][0]);
for(int m=1;m<dvnum+1;m++){
     diaglabelField[m-1] = new JTextField(diagvar[m][0]);
     System.out.println("diaglabelfield= "+diagvar[m][0]);
     diagconfidenceField[m-1] = new JTextField(diagvar[m][1]);
     diagfieldPane.add(diaglabelField[m-1]);
     diagfieldPane.add(diagconfidenceField[m-1]);
}where dvnum is the number of variables. The output from above gives a list of all the variable names, then a list of only those that were accepted into the JTextFields.
Is there a limit as to how many JTextFields I can use? Or an easier way of doing this? If I use a smaller data set (under 15) it works, over that it only accepts 12 or so.
I was thinking JTable could be used, but I would have to pass and build a JTable every time I wanted to look at a different data set for the new index.

That's a long post, but I couldn't figure out from it just what your problem is. I'm guessing that your panel with the JTextFields only has room for 12 of them, and it doesn't scroll to show the others (from 13 to 80).
If I'm right, I would suggest you don't use a bunch of JTextFields to show this data. And since there's only one column of data, you don't really need a JTable either. A JList would work just fine, assuming you don't need to update the data. Put it in a JScrollPane and you'll be able to use as many entries as you like.
