You have two rows with the same date:
{
c: [{
v: new Date(2017,7),
f: "8/2017"
}, {
v: 11855
}, {
v: 9508
}, {
v: null
}, {
v: true
}]
}
This causes the calculation of the minimum distance between data values to
be 0, so the minimum bar width is used. Since duplicated domain values
would actually take up no more space, I'll make a change to ignore the
duplicates. But for now, you'll have to remove the duplicates.
