In the previous article, we learned how to connect our data set and build the first chart. In this article we are going to introduce some of Tableau terms which will be used in many articles of this forum or elsewhere.
Note that the first page we land after connecting to any data is called Data Source page shown below.
While we at data source screen, we can be able to perform the following operation.
Manage our metadata by performing operations like, hiding unnecessary columns,creating groups/calculated fields,changing data types among others.
Chose whether to work with live connection to the data or extracting the data to Tableau in-memory data engine (hyper for those using 10.5 edition).
Now, lets proceed to Sheet 1 and see some of important sections available there.
In above screen, are the sections we will interact with in most of Tableau assignments. See their description below.
Toolbar - this section helps Tableau users access shortcuts to different actions like Saving,creating new sheets,sorting data,highlighting, changing presentation mode among others.
Dimensions - This section holds the discrete variables (in most cases) available in the data.
Measures - This section holds the continuous variables (in most cases) available in the data.
Filters - Filters help user pass the sub-set of data to be used in analysis.
Marks card - Marks card holds five tabs inside i.e Color, Size, Text, Detail & Tool tip. Depending on the kind of analysis, you may see another tab called Shape. This tabs help us format our charts and graphs.
Columns & Rows shelf - this act as our launching pad where we drag our dimensions and measures for visualization to be done.
Show Me tab - This section can be one of the useful part for new users, it helps users create simple charts and graphs by simply selecting the chart that suites the active fields (level of detail).
Other important sections are Dashboard tab and Story tab located at the bottom of screen next to Sheet 1. This two help users in compiling different sheets to create a data story.
I hope this article was useful to you.
