散景中是否有功能仅显示数据表中散点图的放大元素？

Question

当我放大散景散点图时，我试图自动更新数据表。该表应显示该图视图中的所有元素。

这适用于Bokeh版本1.0.4。 Python 3.5

当前，我正在使用box_select来使用从框中选择的元素更新数据表。

from random import random
from bokeh.models import CustomJS, ColumnDataSource, Row
from bokeh.plotting import figure, curdoc
from bokeh.models.widgets import Button, TableColumn, DataTable


x = [random() for x in range(500)]
y = [random() for y in range(500)]

s1 = ColumnDataSource(data=dict(x=x, y=y))
s2 = ColumnDataSource(data=dict(x=[], y=[]))
p1 = figure(plot_width=400, plot_height=400, tools="pan, wheel_zoom, lasso_select, box_zoom, reset", title="Select Here")
p1.circle('x', 'y', source=s1, alpha=0.6)
columns = [TableColumn(field ="x",  title = "X axis"),
           TableColumn(field ="y",  title = "Y axis")]

p2 = DataTable(source =s2, columns = columns, width =155, height = 380)

s1.selected.js_on_change('indices', CustomJS(args=dict(s1=s1, s2=s2, p2=p2), code="""
        var inds = cb_obj.indices;
        var d1 = s1.data;
        var d2 = s2.data;
        d2['x'] = []
        d2['y'] = []
        for (var i = 0; i < inds.length; i++) {
            d2['x'].push(d1['x'][inds[i]])
            d2['y'].push(d1['y'][inds[i]])
        }
        s2.change.emit();
        p2.change.emit();
    """)
)

def get_values():
    print(s2.data)

button = Button(label = "Get selected set")
button.on_click(get_values)

curdoc().add_root(Row(p1, p2, button))

我希望仅从散景数据表中的散点图中看到放大的数据点。
