<!-- Answer --> This is a known issue with multiple related bug reports and fixes. There are two problems at play: 1. **Dash patterns too small to see** – The formula `[(patternIncrement % 5) + 1, (patternIncrement % 3) + 1]` generates patterns like [2, 2] (2px dash, 2px gap), which appear nearly identical to solid lines. [PR #37135](https://github.com/apache/superset/pull/37135) fixed this by using larger patterns like `[(patternIndex % 5) + 4, (patternIndex % 3) + 3]` (4-8px dash, 3-5px gap). 2. **Color matching causing same color for all offsets** – The `timeShiftColor` option (enabled by default) makes time-shifted series inherit their original series' color. When you have a single metric with multiple offsets (1 year ago, 2 years ago, 3 years ago), they all inherit the same base color, making them appear identical. [PR #38473](https://github.com/apache/superset/pull/38473) addressed some color matching issues but the fundamental behavior of matching colors is intentional. **Workaround**: Try unchecking "Match time shift color with original series" in the chart customization options. This will assign distinct colors from your color scheme to each time-shifted series instead of matching them to the original. <!-- Dosu Comment Footer --> *To reply, just mention [@dosu](https://go.dosu.dev/dosubot?utm_source=github&utm_medium=bot-comment&utm_campaign=github-assistant&utm_content=brand-link).* --- <sup>How did I do?
