SalesData: LOAD Num(ID) as ID, Date(Date) as Date, Month, Num(Year) as Year, Num(Sales) as Sales Inline [ ID, Date, Month, Year, Sales 1, 2012-1-1, 1, 2012, 20 2, 2012-1-1, 2, 2012, 21 3, 2012-1-1, 3, 2012, 23 4, 2013-1-1, 1, 2013, 34 5, 2013-2-1, 2, 2013, 35 6, 2013-3-1, 3, 2013, 46 7, 2014-1-1, 1, 2014, 27 8, 2014-2-1, 2, 2014, 30 9, 2014-3-1, 3, 2014, 49 ];
新建线形图表命名为Sales,如图所示,
将Month作为维度,如图所示:
在表达式那个tab中新建两个Expression 如下所示:
ActualSales的表达式如下:
=Sum({$< Year={'$(=Max(Year))'} >}Sales)
PCPSales的表达式如下:
=Sum({$< Year={'$(=Max(Year)-1)'} >}Sales)
点击确定,生成如下图表:
如有疑问,欢迎留言交流。
最近还会再写的几个Topic::
1. 显示所选时间前12个月销售数据;
2. 显示上一销售级别的销售;
3. 计算最近一年的销售数据。

The string data types in MySQL include CHAR, VARCHAR, BINARY, VARBINARY, BLOB, and TEXT. The collations determine the comparison and sorting of strings. 1.CHAR is suitable for fixed-length strings, VARCHAR is suitable for variable-length strings. 2.BINARY and VARBINARY are used for binary data, and BLOB and TEXT are used for large object data. 3. Sorting rules such as utf8mb4_unicode_ci ignores upper and lower case and is suitable for user names; utf8mb4_bin is case sensitive and is suitable for fields that require precise comparison.

The best MySQLVARCHAR column length selection should be based on data analysis, consider future growth, evaluate performance impacts, and character set requirements. 1) Analyze the data to determine typical lengths; 2) Reserve future expansion space; 3) Pay attention to the impact of large lengths on performance; 4) Consider the impact of character sets on storage. Through these steps, the efficiency and scalability of the database can be optimized.

The best tools and technologies for automating the creation of users in MySQL include: 1. MySQLWorkbench, suitable for small to medium-sized environments, easy to use but high resource consumption; 2. Ansible, suitable for multi-server environments, simple but steep learning curve; 3. Custom Python scripts, flexible but need to ensure script security; 4. Puppet and Chef, suitable for large-scale environments, complex but scalable. Scale, learning curve and integration needs should be considered when choosing.
