你的错误看似乎是绑定了图表（有设置为图表的单元格），但图表不存在。
请参考  UI\demo\report\process 报表，和图标相关的例子。

cyzl

首先添加里一个char控件
然后添加子图表，设置子图表的data属性的时候，在他的下边就生成一个data
关闭本页面从新打开，子图表下的data就消失了和示例里的一样

可是，子图表不显示：
如果char控件的auto-load属性设置为true，则报上边的错，图表也不显示；
如果char控件的auto-load属性设置为false，则不报错，也就是不加载吧，但是图表还不显示。

jishuang

chart组件的宽高设置100%，如果放了多个图表或者报表，其他的要延迟加载，auto-load设置为false

cyzl

但是，auto-load设置为false,报表不显示，什么原因？

看示例页面，发现tabPanel下，除了第一个tabPage，其他的tabpage的onSelect时间里都写着一个if，是什么意思？？？

jishuang

默认其他的tabPanel中的报表或者图标不加载，在切换tabPage的时候加载
if中就是判断没有加载就加载一下

cyzl

但是我的加上之后，就报错了Uncaught SyntaxError: Unexpected end of input详细

1. Uncaught SyntaxError: Unexpected end of input

复制代码

看来还是远程一下吧！

jishuang

你好楼主，该问题需要远程，已经通过技术服务QQ加你为好友了，请及时通过，我们会尽快QQ远程。

jishuang

已远程，
用borderLayout，图表的宽高设置为100%的问题
目前的解决方案：
1.设置100%就是现在给你的那个方案，延迟加载
2.设置固定高宽

cyzl

在其他tabPage的onselect中添加方法：

1. justep.xbl('chart1').refresh();

复制代码

同时，报表或图表的width和height设置为固定值，就可以显示了


结贴吧！！！！！！！！！！！！！！！！
