在Chart.JS上设置限制

Question

有没有办法在chart.js中对min和max轴进行硬编码？我已经在小提琴中获得了基本设置，但是在插件的文档中没有看到任何内容。

在第二个注意，有没有办法来防止这样的事情不占用整个画布？我想在可能的60个像素上画图并在那里放置图像。

这里是我当前的代码！

var randomScalingFactor = function(){ return Math.round(Math.random()*100)}; 

var barChartData = { 
    labels : ["Zinc","Boron","Sulphur","Potassium","Nitrogen","Aluminium","Iron"], 
    barstroke: true, 
    datasets : [ 
     { 
      fillColor : "rgba(220,220,220,0.5)", 
      strokeColor : "rgba(220,220,220,0.8)", 
      highlightFill: "rgba(220,220,220,0.75)", 
      highlightStroke: "rgba(220,220,220,1)", 
      data : [1,2,3,4,5,6,7] 
     }, 

    ] 

} 

    var ctx = document.getElementById("canvas").getContext("2d"); 
    window.myBar = new Chart(ctx).Bar(barChartData, { 
     barstroke: true, 
     responsive : true 
    });

多一点挖有想出了他从做文档：

var randomScalingFactor = function(){ return Math.round(Math.random()*100)}; 

var barChartData = { 
    labels : ["Zinc","Boron","Sulphur","Potassium","Nitrogen","Aluminium","Iron"], 
    barstroke: true, 
    datasets : [ 
     { 
      fillColor : "rgba(220,220,220,0.5)", 
      strokeColor : "rgba(220,220,220,0.8)", 
      highlightFill: "rgba(220,220,220,0.75)", 
      highlightStroke: "rgba(220,220,220,1)", 
      data : [1,2,3,4,5,6,7] 
     }, 

    ] 

} 
window.onload = function(){ 
    var ctx = document.getElementById("canvas").getContext("2d"); 
    window.myBar = new Chart(ctx).Bar(barChartData, { 
     barstroke: true, 
     responsive : true, 
     // Boolean - If we want to override with a hard coded scale 
     scaleOverride: true, 

     // ** Required if scaleOverride is true ** 
     // Number - The number of steps in a hard coded scale 
     scaleSteps: 14, 
     // Number - The value jump in the hard coded scale 
     scaleStepWidth: 1, 
     // Number - The scale starting value 
     scaleStartValue: 0 
    }); 
}
