[visualization-api] How to use Custom Images or texts on Combo charts

[Sagar Shirke]

I want to use custom Images or text on combo charts i.e Pointshape.
Something like mentioned below.

var options = {
legend: 'none',
hAxis: { minValue: 0, maxValue: 7 },
pointSize: 30,
series: {
0: { pointShape: '1.png' },
1: { pointShape: '2.png' },
2: { pointShape: 'abc.png' },
3: { pointShape: 'x.png' },
4: { pointShape: 'star.png' },
5: { pointShape: 'p.png' }
}
};

and output should look like below image.

So can anyone let me know how it can be achieved??
