在同一页上显示两个图形

Question

我想在不同的同一页上绘制两个图表 days.But 当第 3 天到来时它应该显示最后两天的图表（意味着第一天的图表不会显示，只有第 2 天和第 3 天) 就像队列 process.I 无法弄清楚我如何移动图形日-wise.I 与 oracle 10g 有数据库连接。

更新数据库后应该如下所示 -

这是我的代码=>

对于每个新的一天，您都可以隐藏或删除顶部的 container-div 并在底部插入一个新的 container-div。然后你只需要绘制一张新图表。

这是一个工作演示 (fiddle):

$(function() {

  function getNewData() {
    var temp = [];
    for (var i = 0; i <= 10; i++) {
      temp.push([i, Math.random()]);
    }
    return temp;
  }

  $.plot("div.placeholder:first", [getNewData()]);
  $.plot("div.placeholder:last", [getNewData()]);

  function newChart() {
    $('div.placeholder:visible:first').hide();
    $('div.placeholder:last').after($('<div>').addClass('placeholder'));
    $.plot("div.placeholder:last", [getNewData()]);
  }

  $('#btn').on('click', newChart);
});
