Hi,

I’d like to order the legends in my own way. I’m plotting a stacked bar chart and legends are shown according to ‘y’ column in same order they are plotting. I want to show legend in my order…

Below is the code of stacked bar chart that is using their way to do legend displaying.
plot = Bar(df, values=‘same_number’, label=CatAttr(columns=[‘x’], sort=False),
title="Stacked chart ", stack=‘y’, legend=‘top_left’,
plot_width=700, plot_height=300, color=color( columns=‘colors’, palette=palettes, sort=False))

Thanks.

Hi,

Each plot has a p.legend property that returns a list of all its legends. There is often only one legend, so p.legend[0] will get you that single legend. Legend objects in turn, have a .items property. It is just a list of "legend items" to render.

Their order in this list is the order they appear visually in the legend.

You can re-order this .items list to be in whatever order you like, although you may have to inspect each item a bit to determine which group it is for, etc.

Thanks,

Bryan
