Q:未被发现的错误:情节的无效的尺寸,宽度为零,高度= null

I am using flot pie chart for showing plotting pie chats for New visitors, Bounce Rate, Search, Traffic . But it shows error in console.

Uncaught Error: Invalid dimensions for plot, width = null, height = null

I have used this html like:

此时此刻我该怎么办?

answer1: 回答1:

I just faced this error. You have to define

style="width:aaapx; height:bbbpx" 

to the div you're filling with the chart. I made this for example

<div ui-jp="plot" id="placeholder" style="width:450px; height:250px" ></div>

and loaded data to #placeholder through jQuery

我只是面对这个错误。你必须定义

style="width:aaapx; height:bbbpx" 

在你的图表填充div。我做了这个例子

<div ui-jp="plot" id="placeholder" style="width:450px; height:250px" ></div>

加载数据通过jQuery #占位符
