(off) *Current implementation:*
For users that suffer from color blindness, it is difficult to distinguish between different colors for the various lines in a line chart since the only difference right now is color.
(on) *Suggestion:*
Add the option to set a pattern for each line in addition to colors. It seems the easiest way to implement this would be to make a special color picker for the "Color by" color picker, where in addition to colors it is also possible to choose between different line styles. See attached screen shot for an idea of how it could look in the visualization.
