Stata - Stacked Area Plot

Stacked space charts are highly effective visible instruments for displaying the composition of a complete amount over time or throughout classes. They excel at displaying the relative contribution of particular person parts to a complete, making them notably helpful for analyzing tendencies in datasets with a number of time collection or categorical variables. This text supplies a complete information to creating and customizing stacked space charts in Stata, protecting varied methods, choices, and concerns for efficient information visualization.

Understanding Stacked Space Charts

A stacked space chart represents information as a collection of stacked areas, the place every space corresponds to a selected part or class. The vertical axis represents the whole amount, whereas the horizontal axis represents the time interval or class. The peak of every space phase represents the contribution of that part to the whole at a given level. The entire peak of the stacked areas at any level alongside the horizontal axis represents the general complete for that time.

This visible illustration affords a number of benefits:

Shows Composition: Clearly reveals the proportion of every part inside the complete over time or throughout classes.
Identifies Tendencies: Reveals tendencies in particular person parts in addition to general tendencies within the complete.
Facilitates Comparisons: Permits for straightforward comparability of the relative contributions of various parts.
Highlights Modifications: Successfully illustrates modifications within the composition of the whole over time.

Creating Stacked Space Charts in Stata

Stata’s graph space command is the first software for producing stacked space charts. The essential syntax is simple:

graph space (sum) yvar1 yvar2 yvar3 ... , stack over(timevar)

The place:

graph space: Specifies the kind of graph.
(sum): Signifies that the areas ought to be stacked. That is essential for making a stacked space chart. Omitting this creates a non-stacked space chart.
yvar1, yvar2, yvar3, …: These are the variables representing the completely different parts or classes.
over(timevar): Specifies the variable representing the time interval or class alongside the horizontal axis.

Instance:

Let’s take into account a dataset with info on gross sales of three completely different merchandise (Product A, Product B, Product C) over 5 years. The info would possibly appear to be this:

Yr	Product A	Product B	Product C
2018	10	15	5
2019	12	18	8
2020	15	20	10
2021	18	22	12
2022	20	25	15

The Stata code to generate a stacked space chart could be:

graph space (sum) ProductA ProductB ProductC, stack over(Yr)

This command will produce a stacked space chart displaying the gross sales of every product through the years, with the whole gross sales for every year represented by the whole peak of the stacked areas.
