你必须重写这个比例，试试这个：(applies to ChartJS v1.x)
window.onload = function(){
var ctx = document.getElementById("canvas").getContext("2d");
window.myLine = new Chart(ctx).Line(lineChartData, {
scaleOverride : true,
scaleSteps : 10,
scaleStepWidth : 50,
scaleStartValue : 0
});

对于chart.js V2 (测试版)，请使用：
var options = {
scales: {
yAxes: [{
display: true,
ticks: {
suggestedMin: 0, // minimum will be 0, unless there is a lower value.
// OR //
beginAtZero: true // minimum value will be 0.
}
}]
}
};有关更多详细信息，请参阅chart.js documentation on linear axes configuration。
