Purpose
This skill creates publication-quality figures for economics papers, using clean styling, consistent scales, and export-ready formats.
When to Use
- Building figures for empirical results and descriptive analysis
- Standardizing chart style across a paper or presentation
- Exporting figures to PDF or PNG at journal quality
Instructions
Follow these steps to complete the task:
Step 1: Understand the Context
Before generating any code, ask the user:
- What is the dataset and key variables?
- What chart type is needed (line, bar, scatter, event study)?
- What output format and size are required?
Step 2: Generate the Output
Based on the context, generate code that:
- Uses a consistent theme for academic styling
- Labels axes and legends clearly
- Exports figures at high resolution
- Includes reproducible steps for data preparation
Step 3: Verify and Explain
After generating output:
- Explain how to regenerate or update the plot
- Suggest alternatives (log scales, faceting, smoothing)
- Note any data transformations used
Example Prompts
- "Create an event study plot with confidence intervals"
- "Plot GDP per capita over time for three countries"
- "Build a scatter plot with fitted regression line"
Example Output
# ============================================
# Publication-Quality Figure in R
# ============================================
library(tidyverse)
df <- read_csv("data.csv")
ggplot(df, aes(x = year, y = gdp_per_capita, color = country)) +
geom_line(size = 1) +
scale_y_continuous(labels = scales::comma) +
labs(
title = "GDP per Capita Over Time",
x = "Year",
y = "GDP per Capita (USD)",
color = "Country"
) +
theme_minimal(base_size = 12) +
theme(
legend.position = "bottom",
panel.grid.minor = element_blank()
)
ggsave("figures/gdp_per_capita.pdf", width = 7, height = 4, dpi = 300)
Requirements
Software
- R 4.0+ or Python 3.10+
Packages
- For R:
ggplot2,scales,dplyr - For Python:
matplotlib,seaborn(optional alternative)
Best Practices
- Use vector formats (PDF, SVG) for publication
- Keep labels concise and readable
- Document data filters used in the figure
Common Pitfalls
- Overcrowded plots without clear labeling
- Inconsistent scales across figures
- Exporting low-resolution images
