Hi all,
I'd like to add a simple legend with two rectangles like the following inside the US map (rectangle No shock, another rectangle with different color Shock)
Did anyone know?
Here is my current code.
clear all; clc;
states = shaperead('usastatehi', 'UseGeoCoords', true);
statenames = {states.Name};
alaska = states(strcmp('Alaska', statenames));
hawaii = states(strcmp('Hawaii', statenames));
f = figure;
hconus = usamap('conus');
for i = 1:51
ccolor = [1 1 1];
geoshow(hconus, states(i), 'FaceColor', ccolor)
end
framem off; gridm off; mlabel off; plabel off
halaska = axes('Parent',f);
usamap('alaska')
geoshow(alaska, 'FaceColor', [0.23 0.44 0.67]);
framem off; gridm off; mlabel off; plabel off
hhawaii = axes('Parent',f);
usamap('hawaii')
geoshow(hawaii, 'FaceColor', [1 1 1]);
framem off; gridm off; mlabel off; plabel off
set(hconus, 'Position',[0.1 0.35 0.85 0.6])
set(halaska,'Position',[0.2 0.42 0.2 0.2])
set(hhawaii,'Position',[0.25 0.43 0.2 0.2])

The rectangular legend can be obtained by changing the 'Display Type' property. Create the handles for 'geoshow' and change the 'Display Type' property. Pass the handles to legends.
h(1) = geoshow(alaska, 'FaceColor', [0.23 0.44 0.67],'DisplayType', 'polygon');
h(2) = geoshow(hawaii, 'FaceColor', [0 0 0],'DisplayType', 'polygon') ;
legend([h(1),h(2)],'No Shock','Shock');
