[visualization-api] Re: specifying N number of x-axis when data is only one
Hi Andrew,
What's wrong with my ticks?
hAxis: {

[visualization-api] Re: specifying N number of x-axis when data is only one
I got it working. However, one last thing I need to fix are the hour values
in the tool tip. It's showing military time. The hour values though in the
axis are displayed correctly.
Here is a screenshot where I clicked one of the points. it's showing 19:00
rather than 7pm.

You have to format the timeofday column. There are no built-in formatters
for the timeofday data type, but you can hijack the DateFormatter for the
purpose:
var formatter = new google.visualization.DateFormat({pattern: 'h:mm a'});
var timeSteps = ['hours', 'minutes', 'seconds', 'milliseconds'];
for (var i = 0; i data.getNumberOfRows(); i++) {
var timeofday = data.getValue(i, 0);
var date = new Date(0);
for (var j = 0; j timeofday.length; j++) {
switch (timeSteps[j]) {
case 'hours':
date.setHours(timeofday[j]);
break;
case 'minutes':
date.setMinutes(timeofday[j]);
break;
case 'seconds':
date.setSeconds(timeofday[j]);
break;
case 'milliseconds':
date.setMilliseconds(timeofday[j]);
break;
}
}
var formattedTime = formatter.formatValue(date);
data.setFormattedValue(i, 0, formattedTime);
}

[visualization-api] Re: specifying N number of x-axis when data is only one
You need to specify the hAxis.ticks option. The ticks option takes an
array of values or object. Values point to the location where a tick mark
(and label) should be placed. Objects have v (required) and f
(optional) properties, where v is the value to place a tick mark at, and
f is the label to place there; if f is not specified, the axis should
format the value according to the format option. Using the ticks option
overrides all other options for controlling the axis tick marks - the only
tick marks that will appear are those you specify, regardless of anything
else in the chart.
Assuming you are using a timeofday column for your times, it would look
like this:
hAxis: {
format: 'h:mm aa',
ticks: [[1, 0, 0, 0], [2, 0, 0, 0], [3, 0, 0, 0], [4, 0, 0, 0], [5, 0,
0, 0], [6, 0, 0, 0]]
}

What I'd like Google Charts to do is display like 6 hours in the x-axis
like 1:00 2:00 3:00 4:00 5:00 3:00
of course, my column totalcount data will only appear above 2:00.
I tried the code below but Google Charts is displaying values for
different time of data. Sometimes it will display with the 30th minute
which I don't want.
hAxis: { format:'h:mm aa',
gridlines: {
count: 6
}
},
When my data starts at 12am, it only display 12am.
What is the solution to this?
Thanks!

It worked Andrew and it looks beautiful! :) Will it work for dates?

Yes, it will works for dates, just use Date objects instead of the
timeofday arrays:
hAxis: {
ticks: [new Date(2014, 7, 1), new Date(2014, 7, 2), new Date(2014, 7,
3), new Date(2014, 7, 4)]
}
