If your domain values, in the first column, come in as datetime values,
then the hAxis will display ticks as datetime values, formatted by the
default rules. See the documentation on dates and times here:
https://developers.google.com/chart/interactive/docs/datesandtimes
You can specify the formatted representation of each value also, using the
{v: value, f: formatted-value} representation of each cell in the table.
Or you can format the values using a DateFormatter. See:
https://developers.google.com/chart/interactive/docs/reference#dateformat
The format of tick values, however, is specified separately from the format
of data values. There is more documentation about axes here:
https://developers.google.com/chart/interactive/docs/customizing_axes
