JQPlot 饼图抛出“无法获取属性‘0’的值：对象为空或未定义”错误

我正在使用基于 JQuery 的图表库 jqPlot（以及其中的饼图插件）来生成一个非常基本的饼图。它在 FF 等中工作正常，但（惊讶！）在 IE 中不行。在 IE 中，它实际上加载正常并且看起来不错，但是一旦我将鼠标滚动到图表上，它就会抛出以下错误：

无法获取属性“0”的值：对象为 null 或未定义

我设置所有内容的方式非常简单：

var optionsObj = {
               seriesColors: ['#3399cc', '#cc6666', '#7ba550', '#ffcc66', '#d17314'],
               grid: {
               },
               seriesDefaults: {
                  renderer: $.jqplot.PieRenderer,
                  rendererOptions: { lineLabels: true, lineLabelsLineColor: '#777'}
               }
               };

            line1 = [['Coffee', 9],['Beer', 4],['TV', 6],['Lost umbrellas', 2],['Bicycle rides', 10]];
            chart = $.jqplot('pieDiv', [line1], optionsObj);

我还应该提到我正在使用包含标签线的修改后的饼图插件，但我得到了这个即使使用常规饼图插件也会出现问题。可以在这里找到：http://blog。 statscollector.com/line-labels-for-the-pie-chart-in-jqplot/

有使用过这个库的人遇到过这样的事情吗？任何帮助将不胜感激。谢谢。

I'm using the JQuery based charting library jqPlot (and the pie chart plugin from it) to generate a very basic pie chart. It works fine in FF, etc. but (surprise!) not in IE. In IE it actually loads okay and looks fine, but once I roll my mouse over the chart it throws the following error:

Unable to get value of the property '0': object is null or undefined

The way I'm setting everything is very straightforward:

var optionsObj = {
               seriesColors: ['#3399cc', '#cc6666', '#7ba550', '#ffcc66', '#d17314'],
               grid: {
               },
               seriesDefaults: {
                  renderer: $.jqplot.PieRenderer,
                  rendererOptions: { lineLabels: true, lineLabelsLineColor: '#777'}
               }
               };

            line1 = [['Coffee', 9],['Beer', 4],['TV', 6],['Lost umbrellas', 2],['Bicycle rides', 10]];
            chart = $.jqplot('pieDiv', [line1], optionsObj);

I should also mention that I'm using the modified pie chart plugin that includes label lines, but I get this problem even when using the regular pie chart plugin. This can be found here: http://blog.statscollector.com/line-labels-for-the-pie-chart-in-jqplot/

Has anyone who has used this library before come across something like this?
Any help would be greatly appreciated.
Thanks.

试试这个

var optionsObj = {
               seriesColors: ['#3399cc', '#cc6666', '#7ba550'],
               grid: {
               },
               seriesDefaults: {
                  renderer: $.jqplot.PieRenderer,
                  rendererOptions: { lineLabels: true, lineLabelsLineColor: '#777'}
               }
               };

            line1 = [['Coffee', 9],['Beer', 4],['TV', 6],['Lost umbrellas', 2],['Bicycle rides', 10]];
            chart = $.jqplot('pieDiv', line1, optionsObj);

Try this

var optionsObj = {
               seriesColors: ['#3399cc', '#cc6666', '#7ba550'],
               grid: {
               },
               seriesDefaults: {
                  renderer: $.jqplot.PieRenderer,
                  rendererOptions: { lineLabels: true, lineLabelsLineColor: '#777'}
               }
               };

            line1 = [['Coffee', 9],['Beer', 4],['TV', 6],['Lost umbrellas', 2],['Bicycle rides', 10]];
            chart = $.jqplot('pieDiv', line1, optionsObj);
