It gave me really a headache to enlarge the horizontal space between my plot area and the legend.
hdl_layout = Layout(
margin_r = 60,
)
does not help, it adds just space to the right.
By changing the parameter legend_x I figured out, that values larger then 1.0 enlarge the gap between plot and legend. Here my example, to understand some fundamental things. I hope it is also helpful for others.
