Hi,
I've got a dynamic DataTable (the number of columns is not fix => database
related).
Here is an exemple of the dataTable:
{
"cols": [{
"id": "Month",
"label": "Month",
"type": "string"
}, {
"id": "2015",
"label": "2015",
"type": "number"
}, {
"id": "Average",
"label": "Average",
"type": "number"
}],
"rows": [{
"c": [{
"v": "January"
}, {
"v": 1
}, {
"v": 1
}]
}, {
"c": [{
"v": "February"
}, {
"v": 2
}, {
"v": 2
}]
}]
}
or
{
"cols": [{
"id": "Month",
"label": "Month",
"type": "string"
}, {
"id": "2015",
"label": "2015",
"type": "number"
},
{
"id": "2016",
"label": "2016",
"type": "number"
}, {
"id": "Average",
"label": "Average",
"type": "number"
}],
"rows": [{
"c": [{
"v": "January"
}, {
"v": 1
}, {
"v": 1
}]
}, {
"c": [{
"v": "February"
}, {
"v": 2
}, {
"v": 2
}]
}]
}
So it depends of the number of years....
I'd like to do somehting like this:
var firstYear = 2015;
var data = new google.visualization.DataTable(jsonData);
var curYear = new Date().getFullYear();
var nbYears= (curYear-firstYear)+1;
var options = {
title : 'My graph',
vAxis: {title: 'CHF'},
hAxis: {title: 'Month'},
seriesType: 'bars',
series: {nbYears: {type: 'line'}}
};
or
var options = {
title : 'My graph',
vAxis: {title: 'CHF'},
hAxis: {title: 'Month'},
seriesType: 'bars',
series: {lastIndex: {type: 'line'}}
};
or
var options = {
title : 'My graph',
vAxis: {title: 'CHF'},
hAxis: {title: 'Month'},
seriesType: 'bars',
series: {'Average': {type: 'line'}}
};
How can I do that?`
Thanks for the answers.
