Horizontal legends

[fbruetting]

Would be cool if we could have legend also in the style of horizontal rows instead of a vertical lists. 😎️

[mkborregaard]

Yes very cool

It would be easy in PGFPlotsX with the help of extra_kwargs, since legend style={legend columns=-1} in pgfplots draws the legend horizontally. For example,

plot(rand(3,2), extra_kwargs=:subplot, legend=:outertop, legend_columns=-1)

Has this feature been added in the GR backend?

[BeastyBlacksmith]

No, currently only implemented for the pgfplotsx-backend
