谷歌圖表工具提示
我的圖表很簡單,是這樣的:用百分比
function drawVisualization() {
var data = google.visualization.arrayToDataTable([
['week', 'rate'],
['1', 0.156],
['2', 0.232],
['3', 0.446],
['4', 0.832],
['5', 0.702],
['6', 0.773],
['7', 0.842],
['8', 0.413],
['9', 0.278],
['10', 0.323],
['11', 0.312],
['12', 0.309],
['13', 0.134],
['14', 0.137]
]);
new google.visualization.LineChart(document.getElementById('visualization')).
draw(data, {curveType: "function",
width: 500, height: 400,
vAxis: {maxValue: 1}}
);
}
但我不知道如何對數據進行格式化欄,顯示作爲工具提示pecentage 。你們能幫忙嗎?
