Watch on YouTube ↗Key takeaways
- 🎯The Wolfram Language should automatically label data series in plots, similar to how it handles associations, to improve clarity, especially for financial data where custom labels are desired over raw tickers.02:13
- 💡The `PlotEvaluate` functionality is problematic and should be eliminated to prevent errors. The concept of auto-evaluated heads (like `Table` and `Map`) could be a more robust solution for handling such cases.05:58
- 🚀Investigate and implement auto-evaluated heads as a potential solution to the issues with `PlotEvaluate`.06:39
- 📈Implementing scale breaks in plots is crucial for handling data with large gaps or outliers, allowing visualization of both low and high ranges without distortion. This includes supporting multiple scale breaks for complex datasets.08:09
- 🔧Develop and refine scale break and out-of-range indicator functionalities, including support for multiple breaks and customizable indicators.11:05
- 🔍Visual indicators for out-of-range data (e.g., dotted lines for curves, arrows for points) are necessary to signal missing data beyond the plotted range, enhancing the interpretability of incomplete datasets.11:18
