Python Bokeh条形图-修改图例框

Question

I am creating a bar chart using Bokeh.Charts.Bar. My problem is that, I have a legend box of 15 labels, and this legend box is covering the right most column (I am using legend='top-right', it would be the same if I change it to 'top-left', it would cover the left most column). So I am trying to create a legend object (bokeh.models.annotations.legend) to set background_fill_data = 0, label_standoff, legend_pedding etc. in order to move the legend box around or make it transparent so that it is easier to create the chart. However, I have achieved nothing so far. Help is really appreciated. Thanks.

bar = Bar(result_df, values='Value', label='Label', legend='bottom_right',
                  stack='Stack', title="Title", bar_width=0.4,
                  color=color(columns='Stack', palette=self.get_colors(5), tools="pan,wheel_zoom,box_zoom,reset,resize,hover")
        hover = bar.select(dict(type=HoverTool))
        hover.tooltips=[("Stack", "@Stack"), (field_name, "@height{" + tooltip_fmt + "}")]


legend = Legend({
              "background_fill_alpha": {
                "value": 0
              },
              "background_fill_color": {
                "value": "#ffffff"
              },

              "label_text_color": {

              "level": "annotation",
              "location": "top_right"
            })
bar.add_legend(legend)

Answer 1

Try setting the legend kwarg in the call to Bar as legend=None . That way, that legend never renders and when you add your custom one, it will be the only one. Just a hunch though.
