Cours 4 sur 5 dans Specialization Data Visualization with Tableau

Leveraging the visualizations you created in the previous course, Visual Analytics with Tableau, you will create dashboards that help you identify the story within your data, and you will discover how to use Storypoints to create a powerful story to leave a lasting impression with your audience. You will balance the goals of your stakeholders with the needs of your end-users, and be able to structure and organize your story for maximum impact. Throughout the course you will apply more advanced functions within Tableau, such as hierarchies, actions and parameters to guide user interactions. For your final project, you will create a compelling narrative to be delivered in a meeting, as a static report, or in an interactive display online.

Dashboard and Storytelling with Data

Welcome to Module 3. In this module, you will go from learning Tableau's six best practices for dashboard design. By the end of this module, you should be able to apply hierarchies, actions, filters, and parameters within Tableau. You will also review five videos associated with the topic and discover how to uncover the story in the data and be able to frame your story.

Welcome back.

In this lesson we will begin our best practices discussion.

I will walk through an example to demonstrate the first

three best practices.

Choose metrics based on why they matter, keep it visual, and make it interactive.

I'm going to be using a different data set,

the World Indicators data set which is packaged with Tableau.

And you can find it as a link under your resources.

The reason I'm choosing this data as opposed to the Sales Superstore one.

Is that the World Indicators data set has a lot more disparate data.

That makes it a little bit more difficult to choose the right metric.

After this lesson, you will be able to choose metrics based on why they matter.

Select the best design principles for your visualization.

And make your visualization interactive.

Let's do this.

So let's say you've been asked as a data analyst.

To develop a metric that illustrates the relationship between infant mortality and

a country's health expenditure as a percentage of GDP.

This is one of the basic types of measurements you do in development

economics all the time.

Which happens to be my field, which I did my graduate work in.

So to do this, So you see these two,

infant mortality and health expenditures as a percentage of GDP here.

So what I would like you to do is we're going to drag both of those to the rows.

So I'm going to take infant mortality and

health expenditures as a percentage of GDP to the rows.

Just like I'm doing here.

Great.

So remember, they're both on rows.

Now The next thing we are going to do,

is we are going to drag years to columns, just like that.

Years to columns.

And we can see here that we have two line graphs.

We have a line graph for infant mortality rate and a line graph for

health expenditures as a percentage of GDP.

Now let's do what we're calling a synchronized n axis.

So let's go down to the Dual Axis as I'm doing on the screen here.

So you do the drop down on the health expenditures as a percentage of GDP and

click on Dual Axis.

This should put that field on the right-hand side.

Let's see what happens.

There you go.

You see that?

We have health expenditures as a percentage of GDP on the right and

infant mortality rate on the left.

I also did a Fit Width just to make it a little bit easier for us to do.

I'm on my laptop so sometimes the laptop doesn't always

render it as well as it could.

So, I just did a Fit Width up at the top.

Right there, yes.

Now I'm going to click on Label and I'm going to Show Mark Labels.

And I'm going to change the label to Match Mark Color.

Right there, Match Mark Color.

And then I'm only going to label the line Ms.

And I'm going to do that for each of the fields.

So I did that first for health expenditures and now I'm doing it for

infant mortality.

And there you go.

You have somewhat of a line graph here.

Now I'm going to take country.

Or rather region.

I could do country also, and do a Show Filter.

I'm going to select a single value drop-down.

And now I'm going to also select a Show Filter for country.

And also do a single value drop-down so that we have two different drop-downs.

And then I'm dragging the country to be under Regions just for formatting.

Now what I'm going to do here is, this is interesting.

I'm going to draw your attention here to the screen and

it says, only relevant values.

And so I want it to be only relevant values.

Because the region is important because it allows us to subset the countries.

So that you don't have to scroll all the way down to the v in all the countries of

the world just to get to Venezuela.

For example, you could just select the Americas and

then select Venezuela after that.

So now I'm going to show you how to actually synchronize this dual axis.

And I want you to

ensure first that the axis range is cleared, if it isn't already.

And then, We are going to synchronize the axis.

Did you see that?

Watch it again on this one.

Right there.

You click on Synchronize Axis.

And then we have synchronized axes that show

both of the percentages in a clearer way.

Okay so now I'm just going to rename the sheet.

I'm going to call this Infant Mortality and Health Expenditure

as a Percentage of GDP.

Looks like I spelled it wrong, this is the way it goes.

[LAUGH] I'm just going to type, in infant, it should be infant,

mortality and health expenditure as a percentage of GDP.

And here we have an axis.

Now you might be asking the question, how does this relate to best practices for

Dashboard?

We'll start with number one, choosing metrics based on why they matter.

The best practice may seem obvious, you only choose and use metrics that you need.

You don't add stuff just because it looks cool.

And so in this case I explicitly stated up front

we're asking to illustrate this relationship.

However, it was left to us to decide how we illustrate it.

This is only one way to do this illustration.

I thought of it from the earliest we have the data to the latest, but

there's so many other ways to do it.

The first time I was thinking about it,

I thought, wouldn't it be good to be on a map?

Or perhaps we could do a scatter plot.

There are so many ways to do it.

What do you think is a good way to illustrate this or not?

Is there a better way to do it?

Best practice number two,

number two on our best practices list is to keep it visual.

To get the readers' attention quickly.

Now I spend a lot of time in the second course of this specialization

talking about preattentive attributes.

And all of these rules that we think about in terms of gestalt principles and

how we visually perceive information.

Now is the time to put that knowledge into practice.

So, best practice one,

select the metrics based on the criteria that you need to select it on.

And then best practice two,

when you show it as a visualization make it as clear as possible.

So no one has any issues with the information and how it's presented.

Best practice number three is to make it interactive.

Does this visualization do that?

I think so.

It has filters and allows you to drill down and examine the underlying data.

The thing about interactivity is that it requires balance.

As you're developing it you need to balance how the visualizations are shown

with the interactivity.

The visualization and interactivity are both helpful,

however putting in too much interactivity can cause issues.

For example, when I created the visualization here I made it clear.

As I mentioned in the last lesson that I want to show only relevant values.

However, let's say that I took out those relevant values

as I'm doing here and then I cleared the filters.

Now I decided I wanted to choose a country.

Let's say I'm going to choose Canada.

And then I clicked on the region and selected Europe.

Look at what happens.

So the bottom line is that if you add more interactivity than what you need.

Your visualization will not be very user friendly.

So make it interactive just make sure you're very thoughtful about

that interactivity piece.

That concludes this lesson.

Where we started to apply the six best practices to a case

demonstrating the first three of the six.

I also demonstrated how to assemble a dashboard

in Tableau according to those best practices.

In the next lesson I will continue to demonstrate the rest of these Dashboard

best practices.

I'll see you there.
