TagCloud大小问题

我正在使用代码根据百分比值显示标签云。 第一次将标记添加到我的数据库时，它看起来很大，然后相对于其他标记缩小（添加的次数越多）。 这是代码：

private void BindTagCloud() { int pro_id = Convert.ToInt32(proj_id); int iteration_id = Convert.ToInt32(iteration); var tagSummaryNegative = from af in db.AgileFactors join psf in db.ProjectStoryFactors on af.AgileFactorID equals psf.AgileFactorID join s in db.Stories on psf.StoryID equals s.StoryID join pim in db.ProjectIterationMembers on s.ProjectIterationMemberID equals pim.ProjectIterationMemberID join it in db.Iterations on pim.ProjectIterationID equals it.ProjectIterationID join pro in db.Projects on it.ProjectID equals pro.ProjectID where pro.ProjectID == pro_id && pro.ProjectID == it.ProjectID && it.ProjectIterationID == pim.ProjectIterationID && pim.ProjectIterationMemberID == s.ProjectIterationMemberID && s.StoryCategoryID == 1 && s.StoryID == psf.StoryID && psf.AgileFactorID == af.AgileFactorID group af by af.Name into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryNegativeIteration = from af in db.AgileFactors join psf in db.ProjectStoryFactors on af.AgileFactorID equals psf.AgileFactorID join s in db.Stories on psf.StoryID equals s.StoryID join pim in db.ProjectIterationMembers on s.ProjectIterationMemberID equals pim.ProjectIterationMemberID join it in db.Iterations on pim.ProjectIterationID equals it.ProjectIterationID join pro in db.Projects on it.ProjectID equals pro.ProjectID where pro.ProjectID == pro_id && pro.ProjectID == it.ProjectID && it.ProjectIterationID == iteration_id && it.ProjectIterationID == pim.ProjectIterationID && pim.ProjectIterationMemberID == s.ProjectIterationMemberID && s.StoryCategoryID == 1 && s.StoryID == psf.StoryID && psf.AgileFactorID == af.AgileFactorID group af by af.Name into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryPositive = from af in db.AgileFactors join psf in db.ProjectStoryFactors on af.AgileFactorID equals psf.AgileFactorID join s in db.Stories on psf.StoryID equals s.StoryID join pim in db.ProjectIterationMembers on s.ProjectIterationMemberID equals pim.ProjectIterationMemberID join it in db.Iterations on pim.ProjectIterationID equals it.ProjectIterationID join pro in db.Projects on it.ProjectID equals pro.ProjectID where pro.ProjectID == pro_id && pro.ProjectID == it.ProjectID && it.ProjectIterationID == pim.ProjectIterationID && pim.ProjectIterationMemberID == s.ProjectIterationMemberID && s.StoryCategoryID == 0 && s.StoryID == psf.StoryID && psf.AgileFactorID == af.AgileFactorID group af by af.Name into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryPositiveIteration = from af in db.AgileFactors join psf in db.ProjectStoryFactors on af.AgileFactorID equals psf.AgileFactorID join s in db.Stories on psf.StoryID equals s.StoryID join pim in db.ProjectIterationMembers on s.ProjectIterationMemberID equals pim.ProjectIterationMemberID join it in db.Iterations on pim.ProjectIterationID equals it.ProjectIterationID join pro in db.Projects on it.ProjectID equals pro.ProjectID where pro.ProjectID == pro_id && pro.ProjectID == it.ProjectID && it.ProjectIterationID == iteration_id && it.ProjectIterationID == pim.ProjectIterationID && pim.ProjectIterationMemberID == s.ProjectIterationMemberID && s.StoryCategoryID == 0 && s.StoryID == psf.StoryID && psf.AgileFactorID == af.AgileFactorID group af by af.Name into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; int maxTagFrequencyNegative = (from t in tagSummaryNegative select (int?)t.tagCount).Max() ??

然而，我想要做的是首先使标签变小（第一次添加），然后增加其大小的次数。 有谁知道我怎么能这样做？ 非常感谢您的帮助！

Answer 1

根据您显示的内容，标签应该看起来很小 – tagGroup.Count（）将为1，GetTagSize将返回“small”

有些东西必须重写这个代码才能强制字体大小 – 只需要把它拿出去，我想你应该得到你所要求的东西。

Answer 2

你为什么不这样做：

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

这样你就可以获得最大数量并反转它们。

Answer 3

我简化了你的代码，在我的盒子上运行它。 一切似乎都没问题。 在这里你可以看到我的测试页面：

Test.aspx文件中：

 <%@ Page Language="C#" AutoEventWireup="true" CodeBehind="Test.aspx.cs" Inherits="WebApplication2.Test" %>        
 
    <%# Eval("Tag") %>   
 
    <%# Eval("Tag") %>   
 
   

Test.aspx.cs：

 using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.Web.UI; using System.Web.UI.WebControls; namespace WebApplication2 { public partial class Test : System.Web.UI.Page { protected void Page_Load(object sender, EventArgs e) { BindTagCloud(); } public class Race { public string GrandPrix { get; set; } public string TeamWinner { get; set; } public int Year { get; set; } } public IEnumerable GetRaces() { yield return new Race { GrandPrix = "Australia", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Malaysia", TeamWinner = "Williams-BMW", Year = 2002 }; yield return new Race { GrandPrix = "Brazil", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "San Marino", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Spain", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Austria", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Monaco", TeamWinner = "McLaren-Mercedes", Year = 2002 }; yield return new Race { GrandPrix = "Canada", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Europe", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Great Britain", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "France", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Germany", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Hungary", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Belgium", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Italy", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "United States", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Japan", TeamWinner = "Ferrari", Year = 2002 }; yield return new Race { GrandPrix = "Australia", TeamWinner = "McLaren-Mercedes", Year = 2003 }; yield return new Race { GrandPrix = "Malaysia", TeamWinner = "McLaren-Mercedes", Year = 2003 }; yield return new Race { GrandPrix = "Brazil", TeamWinner = "Jordan-Ford", Year = 2003 }; yield return new Race { GrandPrix = "San Marino", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Spain", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Austria", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Monaco", TeamWinner = "Williams-BMW", Year = 2003 }; yield return new Race { GrandPrix = "Canada", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Europe", TeamWinner = "Williams-BMW", Year = 2003 }; yield return new Race { GrandPrix = "France", TeamWinner = "Williams-BMW", Year = 2003 }; yield return new Race { GrandPrix = "Great Britain", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Germany", TeamWinner = "Williams-BMW", Year = 2003 }; yield return new Race { GrandPrix = "Hungary", TeamWinner = "Renault", Year = 2003 }; yield return new Race { GrandPrix = "Italy", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "United States", TeamWinner = "Ferrari", Year = 2003 }; yield return new Race { GrandPrix = "Japan", TeamWinner = "Ferrari", Year = 2003 }; } private void BindTagCloud() { int year = 2002; var tagSummaryNegative = from t in GetRaces() where t.Year == 2002 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryNegativeIteration = from t in GetRaces() where t.Year == 2002 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryPositive = from t in GetRaces() where t.Year == 2003 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; var tagSummaryPositiveIteration = from t in GetRaces() where t.Year == 2003 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, tagCount = tagGroup.Count() }; int maxTagFrequencyNegative = (from t in tagSummaryNegative select (int?)t.tagCount).Max() ?? 0; int maxTagFrequencyPositive = (from t in tagSummaryPositive select (int?)t.tagCount).Max() ?? 0; int maxTagFrequencyNegativeIteration = (from t in tagSummaryNegativeIteration select (int?)t.tagCount).Max() ?? 0; int maxTagFrequencyPositiveIteration = (from t in tagSummaryPositiveIteration select (int?)t.tagCount).Max() ?? 0; var tagCloudNegative = from t in GetRaces() where t.Year == 2002 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, weight = (double)tagGroup.Count() / maxTagFrequencyNegative * 100 }; var tagCloudNegativeIteration = from t in GetRaces() where t.Year == 2002 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, weight = (double)tagGroup.Count() / maxTagFrequencyNegativeIteration * 100 }; var tagCloudPositive = from t in GetRaces() where t.Year == 2003 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, weight = (double)tagGroup.Count() / maxTagFrequencyPositive * 100 }; var tagCloudPositiveIteration = from t in GetRaces() where t.Year == 2003 group t by t.TeamWinner into tagGroup select new { Tag = tagGroup.Key, weight = (double)tagGroup.Count() / maxTagFrequencyPositiveIteration * 100 }; if (year == 2002) { 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"; } } } 

在这里你可以看到结果：！[标签云] [1]

我建议您稍微调试一下代码并检查所有数字是否正确。 可能是你在查询中遇到了一些问题（错误的连接或类似的东西），因为所有其他代码对我来说都很好。

希望这可以帮助。

PS你可能在css中有问题吗？
