如何使用堆积条形图在情节区域之外制作图例 [英] How can I make legend outside plot area with stacked bar

问题描述

我的Bokeh库有问题.我需要在情节区域之外创建一个图例框.它适用于圆和面积绘图.我找不到堆叠条形的解决方案，图例下方的解决方案塑造了图形的一部分，因此不可接受(请参见代码下的链接).我想在框中输入图例.

I have a problem with Bokeh library. I need make a legend box outside plot area. It works for circle and area plotting. I can't find the solution for the stacked bar.With the solution below the legend shapes one part of the graph, it isn't acceptable (see link under the code).I would like a legend in the box.

我解决此问题的方法如下(hbar堆栈示例，但解决方案相同)

The way I've solved this is as follows (example for hbar stack but the solution is identical)

# make a figure
p = figure(y_range=uniquesubjects, x_range=(0,600), plot_height=900, plot_width=900, title="Subjects In Trouble!",
        toolbar_location=None, tools="")

# add stacked horizontal bars
p.hbar_stack(headers[0:-1], y='subject_name', color=colors, height=1, source=source, legend=[value(x) for x in legendvals])

# add some graph options
p.xgrid.grid_line_color = None
p.axis.minor_tick_line_color = None
p.outline_line_color = None
p.legend.location = "top_right"
p.legend.orientation = "vertical"

new_legend = p.legend[0]
p.legend[0].plot = None
p.add_layout(new_legend, 'right')

show(p)

我像往常一样创建一个内部图例"，然后制作一个副本，将其从原始位置删除，然后将其添加为外部布局.这是在以下三行中完成的:

I create an "internal legend", as normal and then I take a copy of it, remove it from the original location and add it as a layout outside. This is done in these three lines:

new_legend = p.legend[0]
p.legend[0].plot = None
p.add_layout(new_legend, 'right')
