# SWMM Plot (publication spec) Part of [Agentic SWMM](https://github.com/Zhonghao1995/agentic-swmm-workflow) — install the project first for the executable toolchain (aiswmm CLI, SWMM solver, MCP servers). ## Before calling plot — ask the user When the user asks to plot, **always ask these questions first** before calling any plot tool: 1. **Which entity?** A specific node (junction / outfall) — by name — or a specific link (conduit) — by name? - List 3–5 high-peak-flow candidates from the run's RPT `Link Flow Summary` so the user can pick. 2. **Which attribute?** Node options: `Total_inflow`, `Depth_above_invert`, `Volume_stored_ponded`, `Flow_lost_flooding`. Link options: `Flow_rate`, `Velocity`, `Depth`. 3. **Time window?** Default is the full simulation (24h). Offer to limit to a focus day or HH:MM-HH:MM window if peaks occur in a short period. Do **NOT** silently pick defaults. The user needs control — different plots answer different questions (peak inspection vs continuity vs flooding). ## What this skill provides - A plotting script that reads: - rainfall TIMESERIES from a SWMM `.inp` (one named series at a time); - flow series from a SWMM `.out` binary (via `swmmtoolbox`). - Renders a paired rainfall + node-flow figure with a fixed publication style: - SI units (rain in mm per timestep or mm/h depending on `rainKind`); - rainfall on the top axis, **inverted** (depth grows downward); - flow on the bottom axis; - inward ticks, Arial, no auto title...
