I have a data source:
source = ColumnDataSource(data) as a list of dicts in this schema:
and I want to make scatter plot with a slider for selecting each year interactively.
I understand basic interaction workflow as in http://bokeh.pydata.org/en/latest/docs/user_guide/interaction.html#customjs-for-widgets
However I can not see how to reduce source data to specific year in scatter plot:
plot.scatter(‘x’, ‘y’, source=source)
Can I get some pointers how to do it (without using flask server)?
