I have several lines on my graph made like so:

if true
line([Task1 Task1],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task2 Task2],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task3 Task3],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task4 Task4],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task5 Task5],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task6 Task6],[0 500],'Color',[0 0 0], 'LineStyle','--');
line([Task7 Task7],[0 500],'Color',[0 0 0], 'LineStyle','--');
end

For each task that is occurring and then I have labels on those lines made out like so:

if true
  text(Task1, 500, ' That happened','rotation',90);
text(Task2,500,' This happened','rotation',90);
end

I can only figure out how to label the lines directly on the line at the task value. all the task values are random, so the spacing between them and thus the vertical lines is as well. Simply dividing the task value by 2 does not work. Is there some way to do this I am not realizing?
