- Choose appropriate widths: Longer bars (width 20-30) work well for dashboards, shorter bars (width 10-15) for compact reports
- Use thresholds for status indicators: Perfect for showing health, performance, or risk levels
- Combine with regular metrics: Text plots complement, don't replace, numeric values
- Consider your audience: ASCII styles work everywhere, emoji styles are more visually appealing but require Unicode support
- Leverage density plots for distributions: Great for showing data patterns, outliers, and distributions
The Textplot extension is open source and developed by Query.Farm. Contributions are welcome!
