Google Timeline Chart date box

aaaaaaaahhhhhh · 02-11-2014 1:37pm #1

Hey Guys
This may be very simple to resolve or very complicated.

I have the below code for a Google timeline graph.
When I hover over a bar in the graph, the date in the pop up box only shows the Month and year i.e. Jan 2014.

I need this to show the full date i.e 23 Jan 2014.
Does anyone know how i make this change?

See image for hover box that I refer to.

You need to add a Date Format to the options:

Something like this
var formatter_medium = new google.visualization.DateFormat({formatType: 'medium'});
formatter_medium.format(data,1);

You can find more info here:
