Label Polygons in Mapshow

10 views (last 30 days)
Hi
I have a shapefile of zip codes of NYC. When I use the code, I get this pic and a structure is created, where zip codes are listed in column 5 of the structure. How can I label these zip codes on the map, where it shows?
Thanks,
Candace
%S = shaperead('ZipCode1.shp','UseGeoCoords',true);
S = shaperead('ZipCode1.shp')
mapshow(S)

Thank you! It works. Is there a way to reduce the text size?

You may find internal point of bounding boxes and use text function.
for i=1:263
meanValue = mean(S(i).BoundingBox);
text(meanValue(1),meanValue(2),num2str(S(i).ZIPCODE))
end

To reduce text size, you may use FontSize name-value pair of text funtion
text(meanValue(1),meanValue(2),num2str(S(i).ZIPCODE),'FontSize',fontsize)
