Question

我正在尝试使用Highchart.js绘制动态，混合条形图和折线图。我使用socket.io获取实时数据到我的网页（我使用Flask作为我的网络服务器，所以使用Flask-socketIO）。

我可以使用console.log打印进入我网页的数据，但是我遗漏了一些未在图表中呈现的内容。

我正在尝试添加xAxis以及系列值。

Answer 1

使用addPoint(point, redraw, shift, animation)和设置shift=true一次只显示一个点时出现问题。这将删除之前的点，图表将显示为空。

简单的解决方案是使用：

series1.addPoint(y, false, false, false);
series2.addPoint(z, false, false, false);
myChart.redraw();

使用带有socket.io的HIghchart.js绘制动态混合条形图和折线图，用于实时数据
