Cours 3 sur 5 dans Specialization Data Visualization with Tableau

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.

À partir de la leçon

Mapping

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.

Welcome back.

In the last lesson you learned how to customize your map by changing colors,

shapes and sizes.

After this lesson you will be able to customize your map background

to better tell the story of your data.

Let's go.

When you create a map view,

there are several options to help you control the appearance of the map.

These options are available in the map layers pane.

Let's begin by opening our super shore data set.

And on a new worksheet, let's drag our State field to our view.

To change our background, let's click on Map from our toolbar and

then select Map Layers.

Now, we have many options to choose from to customize our map background.

We can choose the map layers paint to modify how the map appears.

You can change the map background style, hide and

show map layers such as street names and country borders and add data layers.

When you are connected to the Tableau background map,

you can choose between three background styles.

Normal, Light or Dark, to customize the appearance of your map.

Under background, let's click on the down arrow on our style and change it to Dark.

We can also move the Washout slider to the left or

right to change the intensity of the background map.

The farther the slider moves to the right, the more faded the map becomes.

Tableau maps provide several layers that can mark points of interest on the map.

For example, you can overlay streets and highways, county boundaries and

more on the map to give your data context.

Some map layers are only visible as specific zoom levels.

If a map layer is unavailable at your current level of zoom,

it will appear grayed out.

To use layers that are not available, zoom further into the view.

In addition to map layers, you can turn on a variety of

predefined data layers that show you a census information.

Let's click on the down arrow on our layer option, and let's choose Population.

We can see now that Tableau adds a layer of population by state

to our map background.

There are many more options in the pane, so

make sure you spend some time trying each one out.

So far in this course, we have covered what types of geographic data Tableau

allows you to use to create maps.

How to connect to a different data source that may hold geographic data that

you may want to use in your analysis.

How to customize your map by changing colors, shapes and sizes.

And how to customize your map background.

In the next section, we will cover creating Tableau maps with geographic data

not recognized by Tableau, such as street addresses.

See you next time.
