Did you know how easily you can create a scatter plot in Tableau?
Following last month's blog about combined axis charts in Tableau, this month I will show you an example of a combo chart.
What is it?
A scatter plot is a graph that uses dots that represent values for different variables. It uses Cartesian coordinates to show values for [typically] two numerical variables.
When do you use it?
When you want to identify causal relationships, illustrating trends over time, or identifying other patterns in data. For example, you can use a scatter plot to illustrate the relationship between Final GPA and SAT Math scores for a given population of students and show the trend or correlation between the two variables, i.e. is there a positive correlation between GPA and SAT score?
How do you create it?
