Key capabilities include: * **Dual UI Modes**: Choose between a comprehensive **Heatmap Table** to see multiple years at a glance, or a focused **Bar Chart** for a detailed view of a specific year's monthly returns. * **YTD Calculations**: The Heatmap Table automatically calculates and displays both Geometric (Geo YTD) and Arithmetic (Ari YTD) year-to-date performance. * **Deep Historical Lookback**: Visualize up to 30 years of historical monthly data directly on your chart, allowing for robust statistical observation. * **Dynamic Styling**: Fully customizable colors for bullish and bearish returns with dynamic gradient shading based on the magnitude of the returns. The darker the color, the more extreme the return. --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.candelacharts.com/investing/risk-adjusted-performance/monthly-return-heatmap/features.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
