TagCloud大小问题

我正在使用代码来显示基于百分比值的标签云。第一次标签被添加到我的分贝，它看起来很大，然后相对于其他标签收缩（他们被添加的次数越多）。下面是代码：TagCloud大小问题

} 

public string GetTagSize(double weight) 
{ 

    if (weight >= 99) 
     return "xx-large"; 
    else if (weight >= 60) 
     return "x-large"; 
    else if (weight >= 40) 
     return "large"; 
    else if (weight >= 20) 
     return "medium"; 
    else 
     return "small"; 
}

我想这样做，但是，让标签是细小的（第一次它的加入），然后增加它的大小它提到了多次。有谁知道我该怎么做？非常感谢您的帮助！

根据你已经所示的标签应该已经出现小先跟 - tagGroup.Count（）将在1到GetTagSize将返回“小”

东西必须重写此代码强制字体大小大 - 只要把它拿出来，我想你应该得到你所要求的。

这就是我的想法。我更新了我的帖子以显示我的代码。你能看到问题出在哪里吗？谢谢.. – MiziaQ 2011-02-07 00:21:53

你为什么不借此：

weight = (((double)tagGroup.Count()/maxTagFrequencyNegative * 100) - 100) * -1

你把人数最多和扭转他们的方式。

我会试试这个方式 – 2011-02-07 11:22:23

我简化了你的代码在我的包装箱上运行它。一切似乎都没问题。在这里，你可以看到我的测试页面：

       ListView1.DataSource = tagCloudNegativeIteration; 
       ListView1.DataBind(); 

       ListView2.DataSource = tagCloudPositiveIteration; 
       ListView2.DataBind(); 

      } 
      else 
      { 
       ListView1.DataSource = tagCloudNegative; 
       ListView1.DataBind(); 

       ListView2.DataSource = tagCloudPositive; 
       ListView2.DataBind(); 

      } 
     } 

     public string GetTagSize(double weight) 
     { 

      if (weight >= 99) 
       return "xx-large"; 
      else if (weight >= 60) 
       return "x-large"; 
      else if (weight >= 40) 
       return "large"; 
      else if (weight >= 20) 
       return "medium"; 
      else 
       return "small"; 
     } 
    } 
}

我建议你调试一下你的代码，并检查是否所有的数字都是正确的。可能你在查询时遇到了一些问题（不正确的连接或类似的东西），因为所有其他代码对我来说工作正常。

希望这会有所帮助。

P.S.可能是你有问题在CSS？
