I'm trying to write a Java method that will return a string representing a
JSON object, that will be consumed by Google Charts javascript. The JSON
object should look like this:
{
cols: [
{id: 'date', label: 'Date', type: 'string'},
{id: 'activeCampaigns', label: 'Active Campaigns', type: 'number'}
],
rows: [
{c:[{v: new Date(2014, 6, 22), f: '2/28/08'}, {v: 393}]},
{c:[{v: new Date(2014, 6, 22), f: '2/28/08'}, {v: 393}]}
]
}
So far I have:
DataTable data = new DataTable();
ArrayList<ColumnDescription> cols = new ArrayList<ColumnDescription>();
cols.add(new ColumnDescription("summary", ValueType.DATE, "Date"));
cols.add(new ColumnDescription("activeCampaigns", ValueType.NUMBER,
"Active Campaigns"));
data.addColumns(cols);
But how do I add a row with a date in it?
try {
data.addRowFromValues(*/* WHAT GOES HERE??? /**);
} catch (TypeMismatchException e) {
System.out.println("Invalid type!");
}
So far I can only find documentation with strings and numbers.
