Delay Matrix — US Powerball

The delay matrix shows the gap between appearances of each ball across draws. Rows are draws, columns are ball numbers, values are delay counts (0 = drawn in this draw). Color darkens as delay grows. Use period buttons (20/50/100) to adjust the range. The Palette button cycles through 5 color schemes. The Order button reverses the table direction. The Info button changes the left column display (number/date/both). The zero-highlight button (0:) cycles through 3 modes for emphasizing drawn balls: white background, contrasting color, or bold red text.
