课程名称：使用 Tableau 进行可视化分析 课程概述：在这个专项课程的第三部分中，我们将深入探讨 Tableau 在图表、日期、表计算和地图等方面提供的工具。我们将根据所使用数据的类型探讨最佳图表选择，涵盖散点图、甘特图、直方图、子弹图等特定类型的图表，并讨论图表设计指南。我们将定义离散日期和连续日期，研究何时使用它们来展示数据。您将学习如何创建自定义和快速表计算及参数的创建。同时，我们将介绍地图功能，探索 Tableau 如何处理不同类型的地理数据、如何连接多个数据源以及如何创建自定义地图。 大纲： 1. **入门与图表** 描述：本模块将探讨 Tableau 中的图表主题。您将进一步练习如何改变图表的颜色、形状和大小，以及能够解释 Tableau 工具提示的作用及其使用时机。您将讨论选择合适图表的各种指南，并在 Tableau 中创建图表。 2. **日期** 描述：本模块重点介绍 Tableau 中的日期主题。您将能够区分离散和连续日期及其使用场景，利用日期层次结构更好地自定义图表，并在计算字段中创建日期。 3. **表计算** 描述：在本模块中，您将专注于表计算，能够创建新的计算字段以进行字段比较、应用聚合等。您将能使用快速表计算并创建新的计算字段，定制和应用过滤器及参数。 4. **地图** 描述：在最后一个模块中，我们将深入探讨 Tableau 中的地图。您将能够连接不同的数据源，通过更改颜色、形状和大小来自定义地图，制作自定义地理编码地图，并创建包含不被 Tableau 识别的地理数据的地图。此外，您还将能创建双层地图，并展示如何在地图上进行叠加展示。
Name:Getting Started and Charting
Description:In this module, you will explore the topic of charting in Tableau. By now you should already be well versed in how to change colors, shapes, and sizes of charts, so we are going to practice and demonstrate that skill more. You will be able to explain what the Tableau Tooltip does and when to use it. You will be able to discuss the various guidelines for choosing the right chart for your data. You will also create a chart using Tableau.
Name:Dates
Description:This module highlights the important topic of dates within Tableau. You will be able to differentiate between discrete and continuous dates and when to use each. You will be able to use date hierarchies and use the date field to better customize your charts. You will be able to convert between discrete and continuous dates and know when and why you want to switch from one to the other. You will create dates using calculated fields.
Name:Table Calculations
Description:In this module, you will focus on table calculations. You will be able to create new calculated fields to allow you to compare fields, apply aggregations, and more. You will be able use quick table calculations and create new calculated fields. You will be able to customize them and apply filters and parameters to your table calculations.
Name:Mapping
Description:In this final module, we will go more in depths about maps within Tableau. You will be able to connect to a different data sources and customize your maps by changing colors, shapes, and sizes. You will be able to custom geocode a map and create Tableau maps with geographic data that is not recognized by Tableau. You will also be able to create dual layer maps and showcase how to overlay maps on top of one another.
In this third course of the specialization, we’ll drill deeper into the tools Tableau offers in the areas of charting, dates, table calculations and mapping. We’ll explore the best choices for charts, based on the type of data you are using. We’ll look at specific types of charts including scatter plots, Gantt charts, histograms, bullet charts and several others, and we’ll address charting guidelines. We’ll define discrete and continuous dates, and examine when to use each one to explain your data. You’ll learn how to create custom and quick table calculations and how to create parameters. We’ll also introduce mapping and explore how Tableau can use different types of geographic data, how to connect to multiple data sources and how to create custom maps.
