For How do I draw a plot with a variable line width in pgfplots?, after answers and comments started coming in, I realised that I really want a continuous change in line width, and not a discrete one as I answered to a comment in the beginning. This is a detail in the question, but might result in a quite different answer. Which of the following alternatives is right?
- Should I change the question slightly, so that the already given answer no longer answers the question?
- Should I ask a new question, even if it is very similar to the existing question?
- Should I do something else? If so, what?
