我在散景图上有多行,我希望HoverTool显示每行的值,但是使用之前的stackoverflow回答的方法是不行的:
https://stackoverflow.com/a/27549243/3087409
以下是该答案的相关代码段:
fig = bp.figure(tools="reset,hover")
s1 = fig.scatter(x=x,y=y1,color='#0000ff',size=10,legend='sine')
s1.select(dict(type=HoverTool)).tooltips = {"x":"$x", "y":"$y"}
s2 = fig.scatter(x=x,y=y2,color='#ff0000',size=10,legend='cosine')
fig.select(dict(type=HoverTool)).tooltips = {"x":"$x", "y":"$y"}
这是我的代码:
from bokeh.models import HoverTool
from bokeh.plotting import figure
source = ColumnDataSource(data=dict(
x = [list of datetimes]
wind = [some list]
coal = [some other list]
)
)
hover = HoverTool(mode = "vline")
plot = figure(tools=[hover], toolbar_location=None,
x_axis_type='datetime')
plot.line('x', 'wind')
plot.select(dict(type=HoverTool)).tooltips = {"y":"@wind"}
plot.line('x', 'coal')
plot.select(dict(type=HoverTool)).tooltips = {"y":"@coal"}
据我所知,它等同于我链接的答案中的代码,但当我将鼠标悬停在图上时,两个悬停工具框都显示相同的值,{{1} }。

您需要为每个绘图添加渲染器。检查一下。同样不要使用相同的y label
来更改名称。
from bokeh.models import HoverTool
from bokeh.plotting import figure
source = ColumnDataSource(data=df)
plot = figure(x_axis_type='datetime',plot_width=800, plot_height=300)
plot1 =plot.line(x='x',y= 'wind',source=source,color='blue')
plot.add_tools(HoverTool(renderers=[plot1], tooltips=[('wind',"@wind")],mode='vline'))
plot2 = plot.line(x='x',y= 'coal',source=source,color='red')
plot.add_tools(HoverTool(renderers=[plot2], tooltips=[("coal","@coal")],mode='vline'))
show(plot)
