Welcome to this lesson in the module on charting.
I have put together some guidelines for the various charts that tableau offers and
ended up having to split the lesson into several parts.
This really is one large lesson.
But before I introduce it, let's review what we have learned so far.
We've covered the different types of charts available in tableau and
how to change their colors, shapes and sizes.
We've also discussed how to create dual layer charts and
how to use a tableau tooltip.
Now in this final set of videos,
we will focus on some guidelines you consider while creating your charts.
After you finish this lessons, you will be able to identify questions you should ask
before choosing a chart type and determine the purpose for your visualization and
you will be able to select the best charts to visualize what you're trying to say.
There's a lot to cover, so let's get started.
The place you start is with questions.
From the outset, ask yourself, what am I trying to say?
The single most important step you can take to make
a great visualization is to know what you're trying to say.
With the amount of data available today,
anyone can get lost in a world of scatter plots and geocoding.
It is vital that your visualization has a purpose and that you are selective
about what you include in your visualization to fulfill that purpose.
How do you know if your visualization has a purpose?
Well, ask some questions to find out.
Who is your audience?
What questions do they have?
What answers do you want to highlight for them?
What other questions might your visualization inspire?
What conversations may result?
The point is that your viewers should take something away from the time they spend
with your visualization Your next
order of business is to choose the right chart type.
Once you have a purpose for your visualization in mind, it is time to think
about what types of analysis will help you achieve that purpose.
