How do you change the color of an annotation text in Google Chart Tools LineChart ?
Here is an example
google.load(\'visualization\', \'1\', {package
Actually you can. Color of the annotations is the same as line color. Just put a dot in the place you want to make an annotation and set a dot's color to the desirable annotation color.
data.addColumn({type: 'string', role: 'style'});
data.addColumn({type:'string', role:'annotation'});
and then when you add data
'point { size: 14; shape-type: circle; fill-color: #63A74A','Your annotation'
