选择性标签我需要创建一个道场图表道场图表为x轴和网格

http://codebins.com/bin/4ldqp8z/1

在上述链路我的图表具有x轴标签等

电流x轴: 11时许,12:40 PM,下午2:20 & 16:00

为同一标签我有网格线。

现在要求是我只需要3个标签

必需x轴:上午10点,下午1点至下午4点&

图表显示下午9时30之间的数据至4时与间隔10分钟。

扩展axis2d及其一些那么简单。不需要计算任何事情上的步骤。只要给你想要给的任何标签。同时加入

dojo.provide("myDojo.myAxis"); 
dojo.declare("myDojo.myAxis", dojox.charting.axis2d.Default, { 
     calculate: function(min, max, span, labels){ 
      this.inherited(arguments); 
      this.ticks.major= [{ value:4, label:"10am"},{ value:22, label:"1pm"},{ value:40, label:"4pm"}] 
      return this; 
     } 
    }); 
     dojox.charting.axis2d.myAxis = myDojo.myAxis; 

添加型轴

.addAxis("x", { 
       labels: labels, /* Lables are coming from here*/ 
       majorTicks:false, 
       majorTick:{length:4,color:"#FFFFFF"}, 
       majorLabels:true, 
       majorTickStep:10, 
       minorTicks:false, 
       max:40, 
       type:"myAxis", 
       stroke: {color:"#CFCFCF",width:"1"}})

你的X标签设置一个主刻度步骤10明确。从你的标签来看,它应该是18:1是10分钟,6是1小时,18是你想要的3小时。所以这部分很容易。问题是步数从0开始计数,0是上午9:20。你应该从一个不同的数字开始。一种可能的方法是使10am为零。这意味着你应该您的数据和标签移回,这样的:

var labels = [ 
    {value: -3,text: "9:30am"}, 
    {value: -2,text: "9:40am"}, 
    {value: -1,text: "9:50am"}, 
    {value: 0,text: "10am"}, 
    {value: 1,text: "10:10am"}, 
    {value: 2,text: "10:20am"} 
    // and so on 
]; 

或者从上午7时开始,这样的:

var labels = [ 
    // we have no data for 7am, so we skip labels too 
    {value: 15,text: "9:30am"}, 
    {value: 16,text: "9:40am"}, 
    {value: 17,text: "9:50am"}, 
    {value: 18,text: "10am"}, 
    {value: 19,text: "10:10am"}, 
    {value: 20,text: "10:20am"} 
    // and so on 
]; 

尝试不同的映射你的序,您可以达到预期的效果。

PS:您可以控制次要和微小滴答的相同方式。

当我使用负值的轴它创建于左侧和y轴一些黑色的空间仍然从0开始 – gaurang171 2012-08-04 21:20:46

您是否使用为负值的数据呢?只改变标签值是不够的。 – 2012-08-05 01:04:02

嗯。不是我没有。我不知道如何在那里使用负值?就像是?因为它已经是正面的价值。不知道如何用y轴连接他们..任何方式,我通过重写axis2d找到解决方案,所以无需担心任何标签我需要我可以设置在那里的步骤。 – gaurang171 2012-08-05 02:56:34
