javascript - Annotation Google Chart error -

-

who knows, what's going wrong google annotation charts? doesn't work right now. get

uncaught typeerror: cannot read property 'prototype' of null

in console. error in google library, not in code.

i think google updating annotation chart api

testcode: https://jsfiddle.net/lecaoquochung/dsmgl9wj/15/

or google document page https://developers.google.com/chart/interactive/docs/gallery/annotationchart

enter image description here

p.s. met same error today (20160229) testcode above (it's runnning yesterday , haven't fixed code. keep updating)

uncaught typeerror: cannot read property 'prototype' of null  o (anonymous function) e  google.a.c.xc  google.a.c.oa  google.a.oa  (anonymous function)

update 20160301: google has updated chart package ver 44

google.charts.load('44', {'packages':['annotationchart'], 'language': 'ja'});

testcode: https://jsfiddle.net/dsmgl9wj/17/ (annotation chart version 44)
