我一直在尝试使用Holoviews和Bokeh设置标题。我正在彼此叠加3个地块。代码如下:
%%opts Curve [width=900 height=400 show_grid=True tools=['hover'] finalize_hooks=[apply_formatter]]
%%opts Curve (color=Cycle('Category20'))
%%opts Overlay [ legend_position='bottom' ] Curve (muted_alpha=0.5 muted_color='black' )
actual_curve = hv.Curve(df_reg_test, 'date', 'y', label='Actual')
existing_curve = hv.Curve(df_reg_test, 'date', 'Forecast Calls', label='Existing Forecast')
xgb_curve = hv.Curve(df_reg_test, 'date', 'xgb_pred', label='New Forecast')
actual_curve * existing_curve * xgb_curve
如您所见,单个曲线的标签在图例中显示得很好,但是在图的顶部我没有标题。
如何手动设置标题?

我发现可以在叠加选项中添加title_format =“ my new title”选项:
%%opts Curve [width=900 height=400 show_grid=True tools=['hover'] finalize_hooks=[apply_formatter]]
%%opts Curve (color=Cycle('Category20'))
%%opts Overlay [ legend_position='bottom' title_format="my new title"] Curve (muted_alpha=0.5 muted_color='black' )
actual_curve = hv.Curve(df_reg_test, 'date', 'y', label='Actual')
existing_curve = hv.Curve(df_reg_test, 'date', 'Forecast Calls', label='Existing Forecast')
xgb_curve = hv.Curve(df_reg_test, 'date', 'xgb_pred', label='New Forecast')
actual_curve * existing_curve * xgb_curve
现在我的剧情有了标题:

将常规标题添加到覆盖中的另一种方法是使用:
opts.Overlay(title ='覆盖新标题')
下面是在Holoview叠加图上设置标题的示例:
# import libraries
import numpy as np
import holoviews as hv
from holoviews import opts
hv.extension('bokeh')
# create some sample data
data1 = np.random.normal(size=[50, 2])
data2 = np.random.normal(size=[50, 2])
# create your overlay plot
all_plots = hv.Scatter(data1, label='data1') * hv.Scatter(data2, label='data2')
# add your title to your overlay with opts.Overlay()
all_plots.opts(opts.Overlay(title='New title for Overlay'))
生成的图将如下所示:
