I understand your frustration, but don't worry, I can help you with that!

Here are the steps to rotate a graph by 90 degrees in Excel 2003:

1. Select the chart you want to rotate.
2. Click on the "Chart" menu at the top of the screen.
3. Click on "Chart Options".
4. Click on the "Custom" tab.
5. In the "Rotation" section, change the "Degrees" value to 270.
6. Click "OK" to close the "Chart Options" window.

Your chart should now be rotated by 90 degrees, with the x-axis vertical and the y-axis horizontal.

If you want to rotate it back to its original position, simply follow the same steps and change the "Degrees" value to 0.
