Note: This functionality is now part of the unified viz_stackedbar() function. You can use viz_stackedbar(data, x_vars = ...) for the same functionality shown here. See the main stackedbar vignette for comprehensive documentation.

The examples below still work with viz_stackedbars() for backward compatibility, but we recommend using viz_stackedbar() for new code.

This guide covers visualizing responses to multiple Likert-type questions simultaneously.

The multi-variable mode transforms wide survey data (where each question is a separate column) into an elegant stacked bar chart where: - Each bar represents a different survey question - Each stack within a bar represents a response category (e.g., “Strongly Agree”, “Agree”, etc.) - Colors show the distribution of responses across all questions

This approach is particularly valuable for: - Comparing response patterns across multiple related questions - Identifying questions with similar or different response distributions - Visualizing survey batteries (sets of questions with the same response scale) - Showing institutional confidence, satisfaction measures, or attitude scales

The function handles many data preparation tasks automatically, including pivoting from wide to long format, managing haven_labelled variables from SPSS data, and creating publication-ready interactive visualizations.

Migration to Unified Function

To migrate from viz_stackedbars() to viz_stackedbar(), simply change the function name:

# Old way (still works)
viz_stackedbars(data, x_vars = c("q1", "q2", "q3"))

# New preferred way
viz_stackedbar(data, x_vars = c("q1", "q2", "q3"))

All parameters work the same way. The unified viz_stackedbar() also supports crosstab-style charts using x_var + stack_var parameters.

⚙️ Getting Started

Let’s load the necessary libraries and examine our dataset. For this demonstration, we will be using the 2020 wave from the GSS dataset.

library(gssr)
library(dplyr)
library(highcharter)
library(tidyr)
library(dashboardr)

# Load GSS Panel 2020 data
data(gss_panel20)

📋 Data Preparation

Let’s identify and prepare Likert-type questions from the 2016 wave (_1a variables) for ease of use in this practical.

# Look for confidence-related questions (common Likert-type questions in GSS)
confidence_vars <- names(gss_panel20)[grepl("^con.*_1a$", names(gss_panel20))]
cat("Confidence variables found:\n")

## Confidence variables found:

print(confidence_vars)

##  [1] "conarmy_1a"  "conbus_1a"   "conclerg_1a" "condom_1a"   "condrift_1a"
##  [6] "coneduc_1a"  "confed_1a"   "confinan_1a" "coninc_1a"   "conjudge_1a"

# Look for other attitude/satisfaction variables
attitude_vars <- names(gss_panel20)[grepl("(trust|fair|helpful|happy).*_1a$", names(gss_panel20))]
cat("\nAttitude variables found:\n")

## 
## Attitude variables found:

print(attitude_vars)

##  [6] "cantrust_1a"  "fairearn_1a"  "spvtrfair_1a" "trustman_1a"  "trustsci_1a" 
## [11] "unhappy_1a"

# Create a working dataset with key Likert-type variables
gss_likert <- gss_panel20 %>%
  select(
    # Confidence in institutions (if available)
    any_of(confidence_vars),
    # Individual attitudes
    trust_1a, fair_1a, helpful_1a, happy_1a,

  ) %>%
  # Remove completely empty rows
  filter(if_any(everything(), ~ !is.na(.)))

📊 Basic Multi-Question Charts

Example 1: Social Trust and Attitudes

Now that we have our simplified data set, let’s create our first multi-question chart using social attitude variables.

# Define our questions and labels
social_questions <- c("trust_1a", "fair_1a", "helpful_1a")
social_labels <- c(
  "Interpersonal Trust",
  "Fairness of Others", 
  "Helpfulness of Others"
)

# Create basic multi-question chart
plot1 <- viz_stackedbars(
  data = gss_likert,
  x_vars = social_questions,
  x_var_labels = social_labels,
  title = "Social Attitudes and Trust",
  subtitle = "GSS Panel 2016 - Distribution of responses across social attitude questions",
  x_label = "Social Attitude Dimension",
  stack_label = "Response Level",
  stacked_type = "normal"
)

## Note: viz_stackedbars() is now part of viz_stackedbar().
## You can use viz_stackedbar(data, x_vars = ...) for the same functionality.
## viz_stackedbars() will continue to work but consider updating your code.

## Warning: `trust_1a` and `fair_1a` have conflicting value labels.

Example 2: Percentage-Based Comparison

Now let’s create a percentage-based chart to better compare response patterns across questions.

# Create percentage-based chart with custom colors
plot2 <- viz_stackedbars(
  data = gss_likert,
  x_vars = social_questions,
  x_var_labels = social_labels,
  title = "Social Attitudes - Response Distribution",
  subtitle = "Percentage breakdown showing response patterns across questions",
  x_label = "Social Attitude Dimension",
  stack_label = "Response Category",
  stacked_type = "percent",
  tooltip_suffix = "%",
  color_palette = c("#d7191c", "#fdae61", "#ffffbf", "#abdda4", "#2b83ba")
)

## Warning: `trust_1a` and `fair_1a` have conflicting value labels.

🎨 Advanced Customization

Example 3: Custom Response Ordering and Mapping

Let’s create a more sophisticated chart with custom response ordering and cleaner labels.

# First, let's examine what the actual response values are
cat("Unique trust responses:\n")

## Unique trust responses:

print(unique(as.character(gss_likert$trust_1a)))

## [1] NA  "3" "1" "2"

cat("\nUnique fair responses:\n")

## 
## Unique fair responses:

print(unique(as.character(gss_likert$fair_1a)))

## [1] NA  "1" "2" "3"

#TODO: There is a "Series 4" I think for NA values, that needs to be dealt with, i.e. ideally that has its own value?
# Create response mapping for cleaner labels
response_map <- list(
  "can't trust" = "High Trust/Positive", # I know this doesn't make sense, let's just pretend for the sake of the demo
  "can't be too careful" = "Low Trust/Negative", 
  "depends" = "Situational/Neutral",
  "would try to be fair" = "High Trust/Positive",
  "would take advantage of you" = "Low Trust/Negative",
  "depends" = "Situational/Neutral",
  "try to be helpful" = "High Trust/Positive",
  "looking out for themselves" = "Low Trust/Negative",
  "depends" = "Situational/Neutral"
)

# Define response order (from negative to positive)
response_order <- c("Low Trust/Negative", "Situational/Neutral", "High Trust/Positive")

# Create chart with custom mapping and ordering
plot3 <- viz_stackedbars(
  data = gss_likert,
  x_vars = social_questions,
  x_var_labels = social_labels,
  title = "Social Trust Dimensions with Standardized Responses",
  subtitle = "Responses mapped to consistent positive/negative categories",

Example 4: Including Missing Values

Let’s create a chart that explicitly shows missing data patterns.

# Create chart including NA values
plot4 <- viz_stackedbars(
  data = gss_likert,
  x_vars = social_questions,
  x_var_labels = social_labels,
  title = "Social Attitudes Including Non-Responses",

  stacked_type = "percent",
  tooltip_suffix = "%",
  color_palette = c("forestgreen", "darkred", "grey", "yellow")
)

## Warning: `trust_1a` and `fair_1a` have conflicting value labels.
## ℹ Labels for these values will be taken from `trust_1a`.

📝 Working with Different Question Types

Example 5: Happiness and Life Satisfaction

Let’s work with happiness as a different type of Likert scale.

# Create a happiness-focused analysis
happiness_questions <- c("happy_1a")
happiness_labels <- c("General Happiness")

# Check happiness response values
cat("Happiness responses:\n")

## Happiness responses:

table(gss_likert$happy_1a, useNA = "always")

## 
##    1    2    3 <NA> 
##  806 1601  452    8

# Create happiness chart
plot5 <- viz_stackedbars(
  data = gss_likert,
  x_vars = "happy_1a",
  title = "General Happiness Distribution",
  x_label = "Well-being Measure",
  stack_label = "Happiness Level",
  stacked_type = "percent",
  tooltip_suffix = "%",
  color_palette = c("#2E8B57", "#FFD700", "#CD5C5C", "grey")
)

Example 6: Combining Different Question Types

Let’s create a comprehensive chart combining different types of attitude questions. In general, we recommend to have one battery per chart. But, if you really want to have different responses in the same chart, then you’ll need to standardize the response labels before charting, especially if using SPSS data.

#TODO: this chart I dont get it has so many different scales, I think ideally should only be used with same scale?
# Standardize responses before charting
gss_standardized <- gss_likert %>%
  mutate(
    # Convert haven_labelled to character with labels first
    trust_1a_char = as.character(haven::as_factor(trust_1a, levels = "labels")),
    fair_1a_char = as.character(haven::as_factor(fair_1a, levels = "labels")),
    helpful_1a_char = as.character(haven::as_factor(helpful_1a, levels = "labels")),
    happy_1a_char = as.character(haven::as_factor(happy_1a, levels = "labels")),
    
    # Now do the case_when with the actual text labels
    trust_1a_std = case_when(
      trust_1a_char == "Can Trust" ~ "Positive",
      trust_1a_char == "Can't Be Too Careful" ~ "Negative", 
      trust_1a_char == "Depends" ~ "Neutral",
      TRUE ~ trust_1a_char
    ),
    fair_1a_std = case_when(
      fair_1a_char == "Most People Try to Be Fair" ~ "Positive",
      fair_1a_char == "Most People Try to Take Advantage" ~ "Negative",
      fair_1a_char == "Depends" ~ "Neutral",  # Fixed: was trust_1a
      TRUE ~ fair_1a_char
    ),

Example 10: Publication-Ready Chart

Let’s create a fully customized, publication-ready chart.

# Create the most polished example
plot10 <- viz_stackedbars(
  data = gss_likert,
  x_vars = social_questions,
  x_var_labels = c(
    "Interpersonal Trust\n('Can most people be trusted?')",
    "Perceived Fairness\n('Do people try to be fair?')",
    "Perceived Helpfulness\n('Are people helpful?')"
  ),
  title = "Social Capital Dimensions in American Society",
  subtitle = "General Social Survey Panel 2016 (N = 2,867 respondents)\nPercentage distribution of responses across social trust measures",
  x_label = "Social Trust Dimension",
  stack_label = "Response Category",
  stacked_type = "percent",
  tooltip_prefix = "",
  tooltip_suffix = "% of respondents",
  x_tooltip_suffix = "",
  include_na = TRUE,
  na_label_stack = "No response",
  color_palette = c("#b2182b", "#ef8a62", "#fddbc7", "darkgrey"),
  show_var_tooltip = TRUE
)

🎯 Best Practices for Multi-Question Charts

Choose questions with similar response scales

Use questions that have the same or compatible response categories
Consider mapping different scales to common categories when appropriate

Order questions logically

Group related concepts together
Consider ordering by typical response patterns (most positive to least positive)
Place most important questions first

Use appropriate stacking type

Use “percent” for comparing response patterns across questions
Use “normal” when absolute counts matter more than proportions

Handle missing data thoughtfully

Decide whether missing patterns are substantively meaningful
Use include_na = TRUE when non-response patterns are important
Provide clear labels for missing categories

Choose colors carefully

Use consistent color schemes across related charts
Consider the meaning of response categories (positive/negative)
Ensure sufficient contrast between adjacent categories
Test for colorblind accessibility

Customize tooltips for clarity

Include question text in tooltips when helpful
Use appropriate number formatting (percentages vs. counts)
Provide context about sample sizes when relevant

📚 Conclusion

The viz_stackedbars() function provides a powerful solution for visualizing multiple Likert-type survey questions simultaneously. Its key advantages include:

Automatic data transformation from wide to long format
Flexible question labeling for publication-ready displays
Comprehensive customization options for professional presentations
