Question

此时我使用图表显示一天中所有会议记录（1440列）的操作，因此，我有一天1440行。我的'解决方案'是显示一个图像，每行宽度为1像素（1440个图像），但这使用1440像素，我需要在移动设备中使用，所以没有用（小屏幕）。但更大的问题是处理所有问题的加载时间非常长。

我尝试创建自定义图表但没有成功。可以使用Chart.js创建这样的图形吗？

对于每一天（这个例子我有4天，但实际上我将有30天）我有1440列，每列代表一天中的一分钟。颜色根据值改变。

在Chart.js中，我尝试使用此... http://jsfiddle.net/wbvwadkb/

var ctx = document.getElementById("chart").getContext("2d");
var data = {
