Bin are a user-defined grouping of numerical data in the data source.

According to the official Tableau documentation: It's sometimes useful to convert a continuous

measure (or a numeric dimension) into bins.

Have a look at the following image. When we right click a measure, we get the following options:

However, for a dimension (this is because the DATA TYPE of this dimension is a string:

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Tableau_TDS-C01/page_4_img_1.jpg

But what if we have a dimension of type NUMBER (NUMERIC DIMENSION)? See below:

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Tableau_TDS-C01/page_5_img_1.jpg

We can clearly create bins from dimensions too - they just have to be numeric :)

Yes, it is possible to disable highlighting for the entire workbook.

You can show trend lines in a visualization to highlight trends in your data.

To add trend lines to a view, both axes must contain a field that can be interpreted as a number. For

example, you cannot add a trend line to a view that has the Product Category dimension, which

contains strings, on the Columns shelf and the Profit measure on the Rows shelf.

However, you can add a trend line to a view of sales over time because both sales and time can be

interpreted as numeric values.

A geographic role associates each value in a field with a latitude and longitude value.

Assigning a geographic role based on the type of location (such as state versus postcode) helps

ensure that your data is plotted correctly on your map view. For example, you can assign the City

geographic role to a field that contains a list of city names.

To assign a geographic role to a field:

In the Data pane, click the data type icon next to the field, select Geographic Role, and then select

the geographic role you want to assign to the field.

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Tableau_TDS-C01/page_82_img_1.jpg

When you assign a geographic role to a field, Tableau adds two fields to the Measures area of the

Data pane: Latitude (generated) and Longitude (generated).

These fields contain latitude and longitude values and are assigned the Latitude and Longitude

geographic roles. If you double-click each of these fields, Tableau adds them to the Columns and

Rows shelves and creates a map view using the Tableau background map.

Yes! We get different color palettes. They are:

*From the official Tableau documentation*

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Tableau_TDS-C01/page_212_img_1.jpg

To change the color for a value

1) Click on an item on the left, under Select Data Item.

2) Click a new color in the palette on the right. In Tableau Desktop you can hover over a swatch to

identify the color.

3) Repeat for as many values that you want to change.

4) In Tableau Desktop, click OK to exit the Edit Colors dialog box. In Tableau Server or Tableau Online,

simply close the dialog box.

The INNER JOIN keyword selects all rows from both tables as long as there is a match between the

columns. Consider 2 tables "Orders" and "Customers".

If there are records in the "Orders" table that do not have matches in "Customers", these orders will

not be shown!

In fact, the opposite of this is true.

Trick : Whenever you think of joins -> Think that after the join is created, we get 1 single flat

combined (joined) table. This flat combined table is created prior to us creating our visualizations.

This happens at the physical layer.

If you ever think about relationships, know that all tables will remain distinct and separate, and

relationships sit at the logical layer. At run time, when you bring in the dimensions and measures to

create your viz, Tableau very smartly creates the necessary joins, relates the tables and sends queries

to these tables to get the resultant data back in the most meaningful way possible. This allows you to

focus on using your data and revealing insights from it and focus less on the data preparation aspect!

Refer to logical layer vs physical layer from the official

documentation: https://help.tableau.com/current/server/en-us/datasource_datamodel.htm

You can add a reference line to any continuous axis in the view.

To add a reference line:

Drag Reference Line from the Analytics pane into the view. Tableau shows the possible destinations.

The range of choices varies depending on the type of item and the current view.

In a simple case, the drop target area offers three options:

Yes! To concatenate fields, they must be of same data type. However, there is a workaround which

we can use - Type casting. See below:

https://kxbjsyuhceggsyvxdkof.supabase.co/storage/v1/object/public/file-images/Tableau_TDS-C01/page_51_img_1.jpg

Here, State and City are Strings, but Postal Code? Nope. It's an Integer. So we can simply use the

STR() function to convert it into a String, and hence the entire equation becomes valid!

Yes! It is possible to duplicate a field and add it to more than one hierarchy. Right click and choose

duplicate.
