morris.js得出错误的值

Question

我正在使用morris.js绘制图形，但是它在折线图上绘制了错误的值。 弹出窗口显示3，但该行显示为4

绘制图形的代码：

var overviewChart = Morris.Area({
element: 'overviewChart',
  data: $.parseJSON($('#userBlocks').html()),
  xkey: 'y',
  ykeys: ['Blocks', 'Scans'],
  labels: ['Blocks', 'Scans'],
  lineColors: ['#A5C3F7', '#999']
});

为JSON数据解析的文本：

 [{"y":"2014-02-07","Blocks":0,"Scans":0},{"y":"2014-02-08","Blocks":0,"Scans":0},{"y":"2014-02-09","Blocks":0,"Scans":0},{"y":"2014-02-10","Blocks":0,"Scans":0},{"y":"2014-02-11","Blocks":0,"Scans":0},{"y":"2014-02-12","Blocks":0,"Scans":0},{"y":"2014-02-13","Blocks":0,"Scans":0},{"y":"2014-02-14","Blocks":0,"Scans":0},{"y":"2014-02-15","Blocks":0,"Scans":0},{"y":"2014-02-16","Blocks":0,"Scans":0},{"y":"2014-02-17","Blocks":0,"Scans":0},{"y":"2014-02-18","Blocks":0,"Scans":0},{"y":"2014-02-19","Blocks":0,"Scans":0},{"y":"2014-02-20","Blocks":0,"Scans":0},{"y":"2014-02-21","Blocks":0,"Scans":0},{"y":"2014-02-22","Blocks":0,"Scans":0},{"y":"2014-02-23","Blocks":0,"Scans":0},{"y":"2014-02-24","Blocks":0,"Scans":0},{"y":"2014-02-25","Blocks":0,"Scans":0},{"y":"2014-02-26","Blocks":0,"Scans":0},{"y":"2014-02-27","Blocks":0,"Scans":0},{"y":"2014-02-28","Blocks":0,"Scans":0},{"y":"2014-03-01","Blocks":0,"Scans":0},{"y":"2014-03-02","Blocks":0,"Scans":0},{"y":"2014-03-03","Blocks":0,"Scans":0},{"y":"2014-03-04","Blocks":0,"Scans":0},{"y":"2014-03-05","Blocks":0,"Scans":0},{"y":"2014-03-06","Blocks":0,"Scans":0},{"y":"2014-03-07","Blocks":1,"Scans":3}]

好像灰线是3 + 1 = 4而不是3。是否有办法使它变成3？

Answer 1

我的错。 只需将Morris.Area更改为Morris.Line
