plot_dynamic_spectrum

`plot_dynamic_spectrum`¶

Render every spectrum in ctx.spectra as one row of a 2D heatmap.


Category	Visualisation
Backend	`plotly` - renders figures with plotly (optional extra `viz`)
Version	`1.0.0`
Reads	`ctx.spectra` (a list of `Spectrum1D`)
Writes	`figures.dynamic`

All spectra are resampled to a common wavelength grid (linear, taking the intersection of their ranges) before stacking. Use this together with phase_fold or lomb_scargle for variable-star and exoplanet work.

Parameters¶

Parameter	Default	Required	Description
`title`	`'dynamic spectrum'`	-	Figure title.
`n_grid`	`1024`	-	Number of wavelength samples on the common grid.
`colormap`	`'Viridis'`	-	Plotly colour scale name (Viridis, Cividis, Plasma…).

Use it¶

PythonCLIMCP

from spectro_kernel import run_algorithm

output = run_algorithm("plot_dynamic_spectrum", ctx, {
    "title": "dynamic spectrum",
    "n_grid": 1024,
    "colormap": "Viridis"
})

The CLI loads a single 1-D spectrum with --input; this algorithm needs ctx.spectra (a list of Spectrum1D). Run it from Python or as a step of a pipeline preset.

{
  "tool": "plot_dynamic_spectrum",
  "arguments": {
    "session_id": "<session_id>",
    "params": {
      "title": "dynamic spectrum",
      "n_grid": 1024,
      "colormap": "Viridis"
    }
  }
}

Every algorithm is an MCP tool of the same name; describe_algorithm returns this page's metadata as JSON.
