class gdt.core.plot.plot.SAA(saa_def, proj, ax, color='darkred', alpha=0.4, **kwargs)

Bases: PlotElement

Plot the SAA polygon on the Earth.

Parameters:

• saa_def (SouthAtlanticAnomaly) – Object containing the SAA boundary definition

• proj (Cartopy Projection) – The Cartopy projection

• ax (matplotlib.axes) – The axis on which to plot

• color (str, optional) – The color of the SAA polygon

• alpha (float, optional) – The alpha of the interior of the polygon

• **kwargs – Other plotting options

Attributes Summary

alpha	The alpha opacity value, between 0 and 1.
artists	The object references to the individual matplotlib elements
color	The color of the plot element
fill	True if the polygon is filled, False otherwise
hatch	The hatching string
linestyle	The linestyle of the edge
linewidth	The line width of the edge
visible	True if the element is shown on the plot, False otherwise
zorder	The plot element zorder

Methods Summary

hide()	Hide the plot element
in_saa(lon, lat)	Check if a point or points is inside the SAA
remove()	Remove the plot element
show()	Show the plot element
toggle()	Toggle the visibility of the plot element
