Not in the released module yet

basegraphics is still in development and is not part of jjstatsplot 1.0.52. It does not appear in the jamovi menu when you install this release, and the R function is not exported. Everything below describes the intended interface and is published early so the design can be reviewed; option names and defaults may still change before it ships.

It is expected in a future release. For what is available today, see the analysis gallery.

large_subset <- mydata[sample(nrow(mydata), 1000), ]  # Sample for speed

basegraphics(
  data = large_subset,
  plot_type = "scatter",
  x_var = "Age",
  y_var = "OverallTime",
  point_size = 0.8,     # Smaller points for density
  add_grid = FALSE,     # Disable grid for speed
  show_statistics = TRUE
)

Memory-Efficient Plotting 

# Minimize memory usage for resource-constrained environments
basegraphics(
  data = mydata,
  plot_type = "histogram",
  x_var = "Age",
  bins = 10,            # Fewer bins = less memory
  color_scheme = "default",  # Simple colors
  add_grid = FALSE,
  show_statistics = FALSE
)

Visualization Principles

1. Clarity First

  • Use clear, descriptive titles and labels
  • Choose appropriate point sizes for data density
  • Enable grid lines for easier reading

2. Color Strategy

  • Use distinct colors for groups (rainbow, heat)
  • Consider colorblind-friendly palettes
  • Limit to 6-8 groups for clarity

3. Statistical Enhancement

  • Enable statistics for insight generation
  • Add regression lines for trend analysis
  • Show sample sizes for group comparisons

4. Performance Optimization

  • Sample large datasets for interactive exploration
  • Use simpler colors and smaller points for big data
  • Disable unnecessary features for speed

Troubleshooting

Common Issues and Solutions

No Plot Appears

Problem: Plot window is empty Solutions: - Verify x_var is specified - Check that variables exist in data - Ensure data has complete cases for selected variables

Colors Not Showing

Problem: All points appear same color despite group_var Solutions: - Confirm group_var is factor or character - Check that group_var has multiple levels - Try different color_scheme options

Statistics Not Displaying

Problem: show_statistics = TRUE but no statistics appear Solutions: - Verify appropriate plot type (not all support statistics) - Check for sufficient data (need >1 observation) - Ensure variables are numeric for correlation

Pairs/Matrix Plots Empty

Problem: Pairs or matrix plots show error message Solutions: - Ensure dataset has at least 2 numeric variables - Check for adequate sample size (n > 2) - Remove variables with all missing values

Custom Limits Not Working

Problem: Axis limits don’t change despite custom_limits = TRUE Solutions: - Verify custom_limits = TRUE - Ensure x_min < x_max and y_min < y_max - Check that limits are reasonable for your data range

Performance Issues

Problem: Slow plotting with large datasets Solutions: - Sample data for exploration: data[sample(nrow(data), 1000), ] - Use smaller point sizes - Disable grid and statistics for speed - Consider simpler color schemes
