Vertical annotation google charts

Question

my chart looks like this img and my options like this

var options =
{
    height:'100%',
    width: '100%',
    legend: {position:'top'},
    title: 'Celkový součet jednotlivých deficitů k roku 2015',
    bars: 'vertical',
    bar: {groupWidth: "80%"},
    colors: ['#0079C1'],
    vAxis:
    {
        title:'Počet',
        format: 'decimal'
    },
    hAxis:
    {
        slantedText: true,
        slantedTextAngle: 25,
        title:'Deficit'
    },
    bars: 'vertical',

    annotations: {
        textStyle: {
            color: '#000'
        },
        alwaysOutside: true,
        style:'point'
    },
    chartArea: {
        height: '60%'
    }
};

My question is, can you rotate the annotation text verticaly so it doesn't get in the way of others if not is it possible to centre the annotation text to its column?

Another question is regarded to the hAxis you can see that my labels are quite long a i would prefer if some of the long labels broke into half and created a two line label.

Thank you very much for your responses nad sorry for my bad english

Answer 1

You can make the annotated text vertical by including annotations: {style: Line} in the chart options. This is shown in this jsfiddle. However, I haven't (yet) discovered how to center the annotations on the vertical bars.
