我正在使用 JqxPanel、JqxDocking 和 JqxChart。

JqxPanel 包含工作正常的停靠窗口。当我曾经将 JqxChart 放入窗口时，Chrome 给出错误错误:标签处的属性高度 =“-1”(重复 2 次)的负值无效

请有人能在这方面帮助我

JavaScript devicechart.js

                var devicerow = {};

                devicerow["devicenames"] = deviceNames[i];
                devicerow["devicenos"] = deviceNos[i];

最佳答案

我有同样的问题，我通过将包含的 div 的宽度设置得足够大以包含指定设置的图表来解决它。

<div id="jqxChart" style="width:680px; height:400px; vertical-align: top;  display: inline-block; padding: 10px;">

希望对你有帮助

关于javascript - JqxChart给出错误Error : Invalid negative value for <rect> attribute height ="-1"，我们在Stack Overflow上找到一个类似的问题： https://stackoverflow.com/questions/11862064/
