python - Bokeh updating multiple lines -

from painless streaming plots bokeh shows how stream live data of single variable. how stream multiple lines there more 1 y variable.

import time bokeh.objects import glyphrenderer renderer = [r r in curplot().renderers if isinstance(r, glyphrenderer)][0] ds = renderer.data_source while true:     df = pd.io.json.read_json(url+json_call)     ds.data["x"] = x+n*i     ds.data["y"] = df.rssi     ds._dirty = true     session().store_obj(ds)     time.sleep(1.5)     i+=1 

you can update many ds.data[] items before calling session().store_objs(ds).
