I'm trying to add a color BarLegend to a ListLinePlot with multiple lists. With 20+ lists a normal Legend gets long and bulky. Basically, each list line is associated with a different value. I've created a color gradient for the lines using the Hue function but cannot figure out how to get BarLegend to work with ListLinePlot. I've included a sample of the plot I have so far. It would be a much cleaner presentation with a colorbar for the legend. How do I do this, in an elegant way? I'd even settle for a non-elegant method right now. example of what I have

  • $\begingroup$ You should be able to use Epilog (or Prolog) and Inset. Have you already created a BarLegend you want to use? $\endgroup$

  • $\begingroup$ I'm about to go to bed, so I can't give a full answer. But, you want PlotLegends -> BarLegend[{colorFunction, {xmin, xmax}}] as the option. To place it within the plot, wrap BarLegend in Placed. $\endgroup$

1 Answer 1

ListLinePlot[Table[Accumulate[RandomReal[{-1, 1}, 250]], {10}], 
             PlotStyle -> (Hue[#] & /@ Range[0., .9, .1]), 
             ImageSize -> 500, 
             PlotLegends -> BarLegend[{Hue, {0, 10}}, 10, ColorFunctionScaling -> True]]

enter image description here
