[bokeh] [Q] How to access all data of selected points in CustomJS callback

Community Support

The source has an attribute column_names which will give you all
the column_names as an array. You could then iterate over that
array to do whatever you need to access the data.

  I think that's what you're asking for, sorry if I've

misunderstood.

Hy,

I have the following callback:

              self.sources[i].callback =

CustomJS(args=dict(p=p,source=self.sources[i]),
code=“”"

var inds = cb_obj.get(‘selected’)[‘1d’].indices;

var d1 = cb_obj.get(‘data’);

var text = ‘’;

var datatext = ‘’;

if (inds.length == 1)

{

datatext = ('Point '+inds[0]);

              var data = "<p>This is 'myWindow' for Point

“+inds[0]+” : “+d1[‘Col X’][inds[0]]+”

";

              myWindow = window.open( +

encodeURIComponent(data),

              "_blank",

“width=200,height=100”);

myWindow.focus();

}

“”"

)

``

      **            Is there a way to access all columns without knowing their

column name?**

      I can't figure out what data type the cb_obj.get('data')

returns. The self.sources[i] is
a ColumnDataSource(data=self.datadict).

      I want to open a window for every selected point and

display the data of the selected point.

Thanks in advance,

Tom
