Compact-pol H-theta plot (plot_h_theta_cp)#
- polsartools.plot_h_theta_cp(h, theta, ppath=None, cmap='jet', cbar=True, norm='', vmin=None, vmax=None, grey_region=True, zone_lines=True, zone_line_color='k', zone_ids=True, gridsize=200)[source]
Generates and saves a density plot of entropy (H) versus theta (degrees) for compact-pol data, including optional zone lines, zone IDs, and grey regions.
radial axis is 1-H angular axis is 2*theta
Example:#
>>> plot_h_theta_cp(h, theta, ppath="HT_plot.png", cmap='jet', cbar=True, norm='log') This will generates a H/Theta plot from the input arrays and save it as HT_plot.png, using the 'jet' colormap and logarithmic normalization
Parameters:#
- hpath or array-like
path to the Entropy file or Array representing entropy values.
- thetapath or array-like
path to the Theta file or Array representing theta values in degrees.
- ppathstr, optional
Path to save the generated plot. If a folder is given, the plot is saved as ‘htheta_plot_cp.png’ inside that folder. If the file already exists, it will be overwritten.
- cmapstr, optional
Colormap used for the hexbin plot. Defaults to ‘jet’.
- colorbarbool, optional
If True, displays a colorbar representing sample count. Defaults to True.
- normstr, optional
If set to ‘log’, applies logarithmic normalization to the hexbin plot.
- grey_regionbool, optional
If True, fills non-feasible regions of the plot with a grey color to indicate feasible boundaries. Defaults to True.
- zone_linesbool, optional
If True, adds dashed lines to mark different entropy-alpha zones. Defaults to True.
- zone_line_colorstr, optional
Color used for zone boundary lines. Defaults to ‘k’ (black).
- zone_idsbool, optional
If True, labels predefined zones with numerical identifiers. Defaults to True.
- gridsizeint, optional
Number of hexagonal bins used in the plot. Higher values result in finer binning. Defaults to 200.
Returns:#
- None
Displays the plot and optionally saves it to the specified location.
