利用flot画图为啥不显示曲线，但是当鼠标悬停在数据点的时候有该点的数据提示

你是不是没有设置线条颜色啊，你用下面这个试试colors: ["#2F95CC", "#D1A00C"],

colors我设置了也不管用     var plot_options = {

   colors: ["#E3563A"],
grid: { show: true, hoverable: true, clickable: true,colors:"rgb(255,0,0)"},
legend: { show: true},
lines: { show: true,color:"rgb(0,255,0)"},
points: { show: true,color:"rgb(0,0,255)"} ,
xaxis: {ticks:10, mode: "time" , minTickSize: [1, "hour"]},
yaxis: { ticks: 5 },
selection: { mode: "xy" }

}
其中只有grid的color有效能变换颜色点和线还是看不见
感觉对flot设置颜色参数无效连backgroundColor:"rgb(0,0,0)",设置了背景都没变黑还是白色的

这段代码以html为后缀的时候能正常打开，显示里面的flot图形，为什么把代码放到php为后缀的文件中就显示不了flot图形了？
