Visualization

This tutorial explains how to visualize spectral fits and explore the fitted parameters.

Preparing for Visualization

Before visualizing your results, ensure that the data and results are properly loaded. Refer to the Loading Data and Results tutorial for instructions on loading the saved results and initializing the Region object.

Plotting Fitted Spectra

To plot the fitted spectra for a specific position (x, y) in a data cube:

# Plot the fits for position (x, y) on a 3x3 grid for a 2-component model
region.ucube.plot_fits_grid(x, y, ncomp=2, size=3, xlim=None, ylim=None)

3D Scatter Plots

To visualize the fitted parameters in 3D, such as in position-position-velocity (PPV) space:

# Create an interactive 3D scatter plot of the fitted results
region.plot_ppv_scatter(savepath="scatter_plot.html", vel_scale=0.5, showfig=True, auto_open_html=False)
