Tableau 简明教程
Tableau - Show Me
作为一种高级数据可视化工具，Tableau 不需要编写任何自定义代码，就可以通过提供许多分析技术让数据分析变得非常容易。Show Me 就是此类功能之一。它可以用于将必需的视图应用于工作表中的现有数据。这些视图可以是饼图、散点图或折线图。
As an advanced data visualization tool, Tableau makes the data analysis very easy by providing many analysis techniques without writing any custom code. One such feature is Show Me. It can be used to apply a required view to the existing data in the worksheet. Those views can be a pie chart, scatter plot, or a line chart.
每当创建包含数据的工作表时，它都可用在右上角，如下面图片所示。一些视图选项将根据数据窗格中选择的性质而变灰。
Whenever a worksheet with data is created, it is available in the top right corner as shown in the following figure. Some of the view options will be greyed out depending on the nature of selection in the data pane.
Show Me with Two Fields
您可以使用 Show Me 中提供的各种图形和图表轻松地目视分析两个字段之间的关系。在本例中，我们选择两个字段并应用折线图。以下为步骤：
The relation between two fields can be visually analyzed easily by using various graphs and charts available in Show Me. In this case, we choose two fields and apply a line chart. Following are the steps −
-
Step 1 − Select the two fields (order date and profit) to be analyzed by holding the control key.
-
Step 2 − Click the Show Me bar and choose line chart.
-
Step 3 − Click the Mark Label button on the scrollbar.
以下图表展示使用上述步骤创建的折线图。
The following diagram shows the line chart created using the above steps.
Show Me with Multiple Fields
我们可以应用与上述类似的技术来分析多于 2 个字段。本例中的唯一差别在于活动形式中可用的视图较少。Tableau 会自动将不适合所选字段分析的视图变灰。
We can apply a similar technique as above to analyze more than 2 fields. The only difference in this case will be the availability of fewer views in active form. Tableau automatically greys out the views that are not appropriate for the analysis of the fields chosen.
此例中，按住 Control 键选择字段的产品名称、客户姓名、销售额和利润。正如您所观察到的那样，Show Me 中大多数视图都显示为灰色。从活动视图中选择散点视图。
In this case, choose the field’s product name, customer name, sales and profit by holding down the control key. As you can observe, most of the views in Show Me are greyed out. From the active views, choose Scatter View.
下图显示了创建的散点视图图表。
