the JPEG quality factor response
and the other ones like the median or guassian response ... how to plot it?

Looks like the plot() command should work. Am I wrong?

The answer is not clear. Can you be more specific ? or can you post the code ?

She asked "I need to plot...". There is a function called plot that does that. Just put in your array representing the "watermark detector response", or whatever other variable you want:
plot(watermarkDetectorResponse, 'b*-', 'LineWidth', 2);
The question was not "How do I compute the watermark detector response?", the question was literally "how to plot it?" which she asked twice so that's what I answered. I assume she already has the response variable because she did not ask how to compute that and only asked how to plot it.
