#29845 — Text orientation

I will soon need to write a scheduling program that manipulates a 
rectangular matrix with a list of personal names labelling the columns 
and dates labelling the rows. This aspect, along with the processes 
needed to load data into the matrix, manipulate it and save it are well -
understood, but I have a display formatting issue with the column labels: 
is there any way that a Java program can align these labels vertically 
like most spreadsheets can, i.e. display the names vertically with the 
first letter at the top? The matrix I need to display can run to 25 or so 
rows and columns but each cell can be quite small (think of holding two 
10pt characters), which means the whole matrix should easily fit onto a 
display if the column labels can be painted as vertically aligned text.

I can't find any hint that this may be possible with AWT/Swing, but did I 
miss something? Alternatively, is it possible with JavaFX?

Something like this work?

import java.awt.*;
import javax.swing.*;

public class test3 extends JFrame {
     private static final String vertText =
      "<html><body>V<br>e<br>r<br>t<br>i<br>c<br>a<br>l<br> <br>" +
      "T<br>e<br>x<br>t</body></html>";
     public test3() {
         setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
         add(new JLabel(vertText,JLabel.CENTER),BorderLayout.CENTER);
         pack();
         setVisible(true);
     }

     public static void main(String... args) {
         EventQueue.invokeLater(new Runnable() {
             public void run() {
                 new test3();
             }
         });
     }
}

Cute, and more readable than I expected until I ran it. Thats' certainly 
a possibility since, transforming name strings into that HTML format can 
certainly be automated and included in data loading code.

Thanks for the idea, which I must admit hadn't occurred to me, and the 
SSCE.

If you are willing to have the letters sideways, you can do it with
Affine Transform.  

Otherwise you will need FontMetrics and place each letter centered,
and fixed vertical spacing.

You paint each letter at centre line - width/2.

You may find some ideas here.
Swing, but JavaFX should face similar issues.

And this, just because I like it so much.
