Displaying dates in Flot from timestamps - php

Question

I am trying to get my graph to display dates on the x axis instead of the timestamps. I've searched and read other posts and still can't get it to budge. Here's my code:
for($i = 0; $i < 3; $i++)
{
$j = $i + 1;
$query = "SELECT UNIX_TIMESTAMP(date_added)*1000, COUNT(id)
FROM likes
WHERE date_added BETWEEN
DATE_SUB(CURDATE(), INTERVAL $j MONTH)
AND DATE_SUB(CURDATE(), INTERVAL $i MONTH)";
$result = mysql_query($query);
echo mysql_error();
$date = mysql_result($result, 0, 0);
$count = mysql_result($result, 0, 1);
$pair = array( (string)$date, (int)$count );
array_push($data_series1, $pair);
}
$.ajax({
url: 'graph_likes.php?get_data=month',
dataType: 'json',
success: function(returned) {
$.plot($('#container'),
[{
data: returned,
points:
{
show: true
},
lines:
{
show: true
},
color: '#00d6e2',
xaxis:
{
mode: 'time'
}
}]);
}
});

If you want flot to display your timestamps nicely formatted, you can try using the timestamp format option (called timeformat):
...
xaxis:
{
mode: 'time',
timeformat: "%y/%m/%d"
}
...
You find the option explained in this document: http://people.iola.dk/olau/flot/API.txt , look for the section called Time series data.
