TagCloud大小问题 [英] TagCloud size problem
本文介绍了TagCloud大小问题的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用code显示基于百分比值标签云。在第一时间标记被添加到我的分贝，它出现大，然后收缩相对于其它标记（时代更它们添加）。这里是code：
I am using code to display a tag cloud based on percentage values. The first time a tag is added to my db, it appears large, and then shrinks relative to other tags (the more times they're added). Here is the code:
private void BindTagCloud()

我想什么做的，但是，是使小标签在第一（第一次它添加），然后增加它的大小它提到的次数越多。有谁知道我怎么能做到这一点？非常感谢您的帮助！
What I would like to do, however, is make the tag small at first (the first time it's added), and then increase its size the more times it's mentioned. Does anyone know how I could do this? Many thanks for your help!

我简化您的code在我的盒子运行。所有的一切都似乎是确定。在这里，你可以看到我的测试页面：
I simplified your code to run it on my box. And everything seems to be OK. Here you can see my test page:

我要推荐给您调试code位，并检查是否所有的数字都是正确的。可能是你有疑问的一些问题（不正确加入或类似的东西），因为其他所有code为我工作得很好。
I'd recommend to you to debug your code a bit and check if all numbers are correct. May be you have some problems in queries (incorrect join or something like that), because all other code works fine for me.
希望这有助于。
P.S。可能是你在CSS有问题？
