I am using the morris.js library and I would like to customize my graphs so to properly format the date-time present in their legend. At this time, when I pass values as-like 2013-07-26T03:34:41+02:00 (ISO8601) to the ykey then the generated legend content is the following:
I would like to generate the content of legend so to display the 2013-07-26T03:34:41+02:00 in a user-friendly way, maybe something like 03:34:41 (2013-07-26) or just now / 19 seconds ago.
Is it possible? If so, how can I make that?

Reset to default 3If anyone came here looking for an actual legend rather than formatting the hover details on a data point, one of the Morris team made a fiddle showing how to do it with some JS and CSS.
From here.
<script src="http://cdnjs.cloudflare./ajax/libs/raphael/2.1.0/raphael-min.js"></script>
<script src="http://code.jquery./jquery-1.8.2.min.js"></script>
<script src="http://cdn.oesmith.co.uk/morris-0.4.1.min.js"></script>
<style>
#legend {
height: 50px;
background: rgba(127, 127, 127, 0.5)
}
#legend span {
display: inline-block;
padding: 15px 30px;
position: relative;
}
#legend span:after {
padding-left: 4px;
content: '\00a0\00a0\00a0\00a0\00a0\00a0';
text-decoration: line-through;
}
</style>
<body>
<div id="area-example">
</div>
<div id="legend"></div>
</body>
then add this below your JS:
chart.options.labels.forEach(function(label, i){
var legendItem = $('<span></span>').text(label).css('color', chart.options.lineColors[i])
$('#legend').append(legendItem)
})
Use below function and change the body according to your need.
hoverCallback: function (index, options, content) {
var row = options.data[index];
//here row has x and y values
}
If it's only for the date format of the x label that you are aiming, then you should use the dateFormat option :
dateFormat: function (x) {
return moment(x).calendar();
}
It won't change the default hoverCallback and just impact the way the x label will be displayed inside the hover bubble.
In my example I used the moment.js lib to make the date look better.
