Canvas JS导致问题

Question

I am creating a line graph in canvas js. It has the following dataset

    dataPoints: [//array
    {x: new Date(Date.UTC (2012, 00, 1, 1,0) ), y: 26 },
    {x: new Date( Date.UTC (2012, 00, 1,2,0) ), y: 38  },
    {x: new Date( Date.UTC(2012, 00, 1,3,0) ), y: 43 },
    {x: new Date( Date.UTC(2012, 00, 1,4,0) ), y: 29},
    {x: new Date( Date.UTC(2012, 00, 1,5,0) ), y: 41},
    {x: new Date( Date.UTC(2012, 00, 1,6,0) ), y: 54},
    {x: new Date( Date.UTC(2012, 00, 1,7,0) ), y: 66},
    {x: new Date( Date.UTC(2012, 00, 1,8,0) ), y: 60},
    {x: new Date( Date.UTC(2012, 00, 1,9,0) ), y: 53},
    {x: new Date( Date.UTC(2012, 00, 1,10,0) ), y: 60}
    ]
  }
  ]

I understand the 1,2,3 parameters in Date.UTC() but I don't understand the 4th and 5th parameters. What are these? I am using

Answer 1

Date.UTC() can be under this form:

Date.UTC(year, month[, day[, hour[, minute[, second[, millisecond]]]]])  

so in your example:

{x: new Date(Date.UTC (2012, 00, 1, 1,0) ), y: 26

2012 is the year,
00 is the month,
1 is the day,
1 is the hour,
0 is the minute.
Please notice that only year and month are needed while all other parameters are optional.
