javascript - Google charts column chart ignoring 0 values for annotation positioning -


the issue having annotation positioning in google charts column chart not respecting 0 values in data set , such not appearing outside column configured.

instead appearing within column (depending on height) not expected behavior , looks this:

incorrect google charts graph

you can see 21 cat b. starting bottom 3 cat d instead of @ top cat a.

i have above example coded here: http://jsfiddle.net/7x6lxr3t/2/ can see chart data follows:

var data = [     ["statuses", "definition", "dev", "test", "closed", {type: 'string', role: 'annotation'}],     ["cat a.", 28, 25, 3, 7, 63],     ["cat b.", 3, 19, 0, 0, 21],     ["cat c.", 0, 0, 0, 0, 0],     ["cat d.", 0, 3, 0, 0, 3] ]; 

and annotations configured follows:

    annotations: {         alwaysoutside: true,         textstyle: {             fontsize: 14,             bold: true,             color: '#000000'         }     }, 

and know last 0 value before annotation because if change cat b. data to:

["cat b.", 3, 19, 0, 1, 21], 

the annotation in correct positioning:

corrected cat. b column

any suggestions appreciated.
