When I want to plot coordinate data, I know that I can color individual scatter points using defined colors using
point meta=explicit. The line segments between two points seem to be colored by an averaged color of the two endpoints.
1) Can I force the color of the line segments to be either the same as the start or endpoints (rather than an averaged color)
2) For black/white plots different gray shades are sometimes hard to distinguish. Is it possible to give the line segments individual styles (i.e. dashed, dotted).
Some background: I want to plot a decreasing curve where different segments represent different phases that need to be distinguishable.
