@All,
As I wasn't satisfied with the result of my first serie, so I rebuild the backgrounds and the pointers:
• The innerside (blue to yellow) of the backgrounds is more clear now.
• the x-line can remained where it was, but the little graduation-lines are deleted to make the background more universal.
• The demensions of the backgounds are changed to 183x52 pixels (QVGA) and to 276x104 (VGA).
• The demensions of the pointers are changed to 4x42 pixels (QVGA) and to 8x84 (VGA).
