Pat*_*ick 5 variables graph mouseclick-event bokeh
我有一个带有一些点的散景图,我试图捕捉属于MouseClick上任何一点的变量.代码示例在本文下面.
使用OpenURL方法一切都按预期工作.变量@ref的值将放入URL中,URL将在新窗口中打开.
但是,使用CustomJS不起作用.taptool回调中的javascript工作(带有URL的链接被添加到当前页面),但现在变量@ref作为字符串传递; 它的值不会放入URL中.
有谁知道如何让CustomJS版本正确地将@ref变量传递给url?
代码示例:
使用OpenURL:
from bokeh.plotting import figure, ColumnDataSource
from bokeh.models import HoverTool, TapTool, OpenURL
source = ColumnDataSource(
data=dict(
x=[x for x in range(0, 200)],
y=[y for y in range(0, 200)],
ref=[x + y for x in range(0, 200) for y in range(0, 200)]
)
)
hover = HoverTool(
tooltips=[
("ref", "@ref"),
("(x,y)", "($x, $y)"),
]
)
tools = [hover, 'box_zoom,box_select,crosshair,resize,save,reset, tap']
url = "http://domain.com/dosomething?reference=@ref"
fig = figure(x_range=(0, 200), y_range=(0, 200), tools=tools)
fig.circle('x', 'y', source=source)
taptool = fig.select(type=TapTool)
taptool.callback = OpenURL(url=url)

使用CustomJS:
from bokeh.plotting import figure, ColumnDataSource
from bokeh.models import HoverTool, TapTool, CustomJS
source = ColumnDataSource(
data=dict(
x=[x for x in range(0, 200)],
y=[y for y in range(0, 200)],
ref=[x + y for x in range(0, 200) for y in range(0, 200)]
)
)
hover = HoverTool(
tooltips=[
("ref", "@ref"),
("(x,y)", "($x, $y)"),
]
)
tools = [hover, 'box_zoom,box_select,crosshair,resize,save,reset, tap']
url = "http://domain.com/dosomething?reference=@ref"
fig = figure(x_range=(0, 200), y_range=(0, 200), tools=tools)
fig.circle('x', 'y', source=source)
taptool = fig.select(type=TapTool)
taptool.callback = CustomJS(args=dict(source=source), code="""
var mydiv = document.getElementById("link");
mydiv.innerHTML = "<a href='""" + url + """'>link</a>";
""")
