I'm aware of how to create a dual-axis chart using two different measures for the Y-axis. Is there a way for me to create a dual-axis chart using a same measure but on two different range in the dual-axis? For example, I have a column which contains revenue, I want to create a dual-axis chart where one axis has revenue for Year 2013, and the other with revenue for Year 2014. Edit: my aim is to create a line chart for revenue Year 2013, and bar chart for revenue Year 2014, on the same chart. See picture below is what I have done to have FY13 and FY14 values for each month and running monthly

Tableau generally works best when input data is in "normalized" format , rather than cross-tab. This is also referred to as converting from "wide format" to "long format". That is, converting from: To: Tableau provides a "reshaping tool" for Excel users , but if you don't have Excel, you're stuck. So how can you get a spreadsheet into this format, without using Excel? Well, you can use this handy Google Sheets script I made. /* normalizeCrossTab: Converts crosstab format to normalized form. Given columns abcDE, the user puts the cursor somewhere in column D.

Tableau是一种BI工具，能够帮助大家查看并理解数据的商业智能型软件。 一．Tableau的组成部分 工作表(work sheet):又称为视图，是可视化分析的基本单元。 仪表盘(dashboard):是多个工作表和一些对象(如图像、文本、网页和空白等)的组合，可以按照一定方式对其进行组织和布局，以便揭示数据关系和内涵。 故事(story):是按顺序排列的工作表或仪表盘的集合，故事中各个单独的工作表或仪表板称为”故事点”。可以使用创建的故事，向用户叙述某些事实，或者以故事方式揭示各种事实之间的上下文或事件发展的关系。 工作薄(workbook):包含一个或多个工作表，以及一个或多个仪表板和故事，是用户在Tableau中工作成果的容器。用户可以把工作成果组织、保存或发布为工作簿，以便共享和储存。 二．Tableau的设计流程 1.连接到数据库； 2.构建数据视图； 3.增强视图； 4.创建工作表； 5.创建和组织仪表盘； 6.创建故事。 三．Tableau的基本操作 1.字段的操作 合并字段 拆分字段 字段分层 字段分组 计算字段 集 创建合并集 2.函数与计算 3.表计算类型 差异计算 百分比差异计算 总额百分比计算 排名计算 百分比计算 汇总计算 4.排序与筛选 排序：手动排序、计算排序 筛选：顶部筛选器、条件筛选器、上下文筛选器、通配符筛选器 5.参数 直接创建参数

I am trying to set up a filter or parameter for different date ranges in Tableau, such as: Previous Week Previous 4-Weeks Previous 8-Weeks based on the most recent data in the database. Is this possible? Edit : I should have been more clear here. Is it possible to only have these options in the filter and have it based on the maximum date in the database? Update Based on your comment and updated question, you can do it as you intend, though it isn't as straight-forward. NOTE: I did this very quickly and with a random data set, so it will be important for you to test this thoroughly with your

I have a set of data in the following format: Resp | Q1 | Q2 P1 | 4 | 5 P2 | 1 | 2 P3 | 4 | 3 P4 | 6 | 4 I'd like to show the count and % of people who gave an answer greater than 3. So in this case, the output would be: Question | Count | Percent Q1 | 3 | 75% Q2 | 2 | 50% Any suggestions? Although it sounds like a fairly easy thing, it is a bit more complicated. Firstly your data is not row based so you will have to pivot it. Load your data into Tableau In the DataSource Screen choose column Q1 and Q1, right click on them and chosse "Pivot" Name the column with the answers "Answers" (just for
