How do I label individual data points on an imagesc plot?

I just want to label specific points in the plot with their coordinates. Does anybody know how I could go about doing this?
Thanks

Would you consider using the text() function?

Yes that was my plan. But I don't know how to isolate the points that I want to label. Also, should I just use num2str command to create the label?

Well obviously you have to know the coordinates of what you want to label. Then you create your text label with sprintf() and then put it over the image with text(). For example:
textLabel = sprintf('(%.2f, %.2f)', column, row);
text(row, column, textLabel);
