Hi Anne,

To label the longitude and latitude on a "pcolor" plot in MATLAB with specific labels like "5° East," "150° East," "110° West," and so on, you can customize the tick labels of the axes. Here's how you can achieve this:

1. Set the tick positions for both the x-axis (longitude) and y-axis (latitude).
2. Customize the tick labels to display the desired text.

The below code snippet demonstrates the above steps:

% Set the tick positions
xticks([-110, 5, 150]);
yticks([-80, -40, 0, 40, 80]);

% Set the tick labels
xticklabels({'110° West', '5° East', '150° East'});
yticklabels({'80° South', '40° South', '0°', '40° North', '80° North'});

For more details, please refer to the following MathWorks documentations:

• xticks - https://www.mathworks.com/help/matlab/ref/xticks.html
• xticklabels - https://www.mathworks.com/help/matlab/ref/xticklabels.html

Hope this helps!
