I am generating column chart passing the following data.
I want the dates to be formatted as MMM,yyyy i.e. i do not want day to be
displayed.
I tried using dateformatter but it does not work. I get an error like
undefined function.
google.setOnLoadCallback(drawChart);
function drawChart() {
var data = google.visualization.arrayToDataTable([
['Year', 'Sales', 'Expenses'],
[new Date(2314, 2, 15), 1000, 400],
[new Date(2314, 3, 16), 1170, 460],
[new Date(2314, 4, 17), 660, 1120],
[new Date(2314, 5, 18), 1030, 540]
]);
var dateformatter = google.visualization.DateFormat({
pattern: "MMM d, ''yy" });
formatter.format(data, 0);
var chart = new google.visualization.ChartWrapper({
chartType: 'ColumnChart',
containerId: 'chart_div',
dataTable: data,
options: {
'title': 'CustomerSalesData',
'chartOptions': {
'hAxis': { 'title': 'Year', 'titleTextStyle': {
color: 'red' }, 'slantedText': true },
'vAxis': { gridlines: { 'color': 'gray', 'count':
20} },
'chartArea': {
'top': 70,
'left': '5%',
'height': 550,
'width': '65%'
}
}
}
});
chart.draw();
}
