# Lines on Maps in MATLAB®

How to make Lines on Maps plots in MATLAB® with Plotly.

## Create Geographic Plot

Plot a straight line between two points on a map. Specify the endpoints of the line using the coordinates of Seattle and Anchorage. Specify latitude and longitude in degrees.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;


Plot the data on a map. Customize the appearance of the line using the line specification 'g-*'. Adjust the latitude and longitude limits of the map using geolimits.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geolimits([45 62],[-149 -123])

fig2plotly(gcf);


## Add Text to Geographic Plot

Plot a straight line between two points on a map. Specify the endpoints of the line using the coordinates of Seattle and Anchorage. Specify latitude and longitude in degrees.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;


Plot the data using geoplot. Customize the appearance of the line using the line specification 'g-*'. Adjust the latitude and longitude limits of the map using geolimits.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geolimits([45 62],[-149 -123])

fig2plotly(gcf);


Identify Anchorage using the text function.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geolimits([45 62],[-149 -123])

text(latAnchorage,lonAnchorage,'Anchorage');

fig2plotly(gcf);


Identify Seattle using the text function. Adjust the alignment of the text label by specifying properties of the Text object.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'g-*')
geolimits([45 62],[-149 -123])

text(latAnchorage,lonAnchorage,'Anchorage');

text(latSeattle,lonSeattle,'Seattle',...
'HorizontalAlignment','right',...
'VerticalAlignment','bottom');

fig2plotly(gcf);


## Customize Individual Lines on Map

Specify the latitude and longitude coordinates of Seattle, Anchorage, and Point Barrow.

latSeattle = 47.62;
lonSeattle = -122.33;

latAnchorage = 61.20;
lonAnchorage = -149.9;

latPtBarrow = 71.38;
lonPtBarrow = -156.47;


Plot straight lines from Seattle to each of the other two cities. Draw a solid yellow line from Seattle to Anchorage and a dotted blue line between Seattle and Point Barrow. Adjust the latitude and longitude limits of the map using geolimits.

latSeattle = 47.62;
lonSeattle = -122.33;

latAnchorage = 61.20;
lonAnchorage = -149.9;

latPtBarrow = 71.38;
lonPtBarrow = -156.47;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'y-',...
[latSeattle latPtBarrow],[lonSeattle lonPtBarrow],'b:')
geolimits([44 73],[-149 -123])

fig2plotly(gcf);


Label each city on the map using the text function.

latSeattle = 47.62;
lonSeattle = -122.33;

latAnchorage = 61.20;
lonAnchorage = -149.9;

latPtBarrow = 71.38;
lonPtBarrow = -156.47;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],'y-',...
[latSeattle latPtBarrow],[lonSeattle lonPtBarrow],'b:')
geolimits([44 73],[-149 -123])

text(latAnchorage,lonAnchorage,'Anchorage');
text(latPtBarrow,lonPtBarrow,'Point Barrow');
text(latSeattle,lonSeattle,'Seattle',...
'VerticalAlignment','bottom');

fig2plotly(gcf);


## Use Chart Line Properties to Customize Appearance of the Line

Plot a straight line between two points on a map. Specify the endpoints of the line using the coordinates of Seattle and Anchorage. Specify latitude and longitude in degrees.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;


Plot the data using geoplot. Adjust the latitude and longitude limits of the map using geolimits. Customize the appearance of the line by specifying the LineWidth and Color properties.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage],...
'LineWidth',2,'Color',[.6 0 0])
geolimits([45 62],[-149 -123])

fig2plotly(gcf);


## Change Basemap Used in Geographic Plot

Plot a straight line between two points on a map. Specify the endpoints of the line using the coordinates of Seattle and Anchorage. Specify latitude and longitude in degrees.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;


Plot the data using geoplot. Adjust the latitude and longitude limits of the map using geolimits.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage])
geolimits([45 62],[-149 -123])

fig2plotly(gcf);


Change the basemap used in the plot using the geobasemap function.

latSeattle = 47.62;
lonSeattle = -122.33;
latAnchorage = 61.20;
lonAnchorage = -149.9;

geoplot([latSeattle latAnchorage],[lonSeattle lonAnchorage])
geolimits([45 62],[-149 -123])
