Hi Samuel,
What you want to use is the explicit 'ticks' option for the vertical axis
to specify the values where you want those horizontal gridlines to show
up. If you also want the labels to be like in your example, 'y1', ...
'y5', then you'll want to specify each tick with its formatted value as
well, like so:
vAxis: {
ticks: [ { v: 10, f: 'y1' }, ..., { v: 50, f: 'y5' } ]
}
