I have a couple of question in regards to LaTeX ability to overlay text on a graph at a specific point. The background: I have a time-series plot that I load in to LaTeX using a txt file and the pgfplots package.

  1. Is it possible to display the y-coordinate for a selected few x-coordinates in a graph and not for any other x-coordinates?
  2. Is it possible to display and overlay text , above the plot-line, at a given x-coordinate?
  3. If the second question is not possible, then how could I overlay text on top of a graph at a given part of the graph, not necessarily at a specific x-coordinate observation.

    Please include a Minimal Working Example. All questions should include a small complete document people can compile to reproduce the issue. – cfr Apr 07 '14 at 02:56
