Hi Neil,
You can constrain the lower end of the vertical axis like so:
options = {
...
vAxis: { viewWindow: { min: 0 } }
}
Since we can see 20 gridlines on your vertical axis, I suspect you have
specified "count: 20", and if so, the chart tries its best to show 20
gridlines, with a bit of margin around the lowest and highest values in
your data. You might be better off specifying "count: -1" so it will use a
dynamically computed number of gridlines.
Another option, if you want specific gridline values, is to use the 'ticks'
option to explicitly provide the array of values you want.
