I am using the Google Visualization API to display an area chart. The
x-axis is of type 'datetime', and the y-axis is of type 'number'. When I
display times, times are displayed in the specified time zone in the tool
tips of the chart. Times are displayed in the time zone of the browser
along the hAxis. I would like to display the same times in both locations.
First, I construct the DataTable using a for loop with this body.
data.addRow([new Date(year + "-" + month + "-" + day + "T" + hour + ":" +
minute + ":" + second + "-05:00"), chartsdata[i].count]);
One of the strings is "2014-02-10T10:00:00-05:00". I would like both the
tooltip and the hAxis to display "2014.02.10 10:00 -0500".
To format times in the tooltips, I use this code:
var formatter_long = new google.visualization.DateFormat({pattern: "yyyy.MM.dd
HH:mm ZZZ", timeZone: -5 });
formatter_long.format(data, 0);
To display times along the hAxis, I use this code:
hAxis: { slantedText: true, slantedTextAngle: 60, textStyle: { color:
'green' }, format: 'yyyy.MM.dd HH:mm ZZZ', timeZone: -5, textStyle: {
fontSize:10} },
I have not found a property of hAxis to specify the time zone. The result
is that
Tooltip time = 2014.02.10 10:00 -0500
hAxis time = 2014.02.10 07:00 -0800
In other words, the tooltip is correct, but the hAxis labels are not. How
can I resolve this mismatch?
Thank you.
