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. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com. ## Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation by asking a question. Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters: ``` 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 what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case. 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.
