default = first(Calories_Burned)))
# Calculate cumulative sum of changes
weekly_calories <- weekly_calories %>%
mutate(Cumulative_Calories = cumsum(Change))
# Create the waterfall chart
waterfall_chart <- ggplot(weekly_calories, aes(x = factor(Week), y = Change)) +
geom_bar(stat = "identity", aes(fill = Change > 0), show.legend = FALSE) +
geom_line(aes(y = Cumulative_Calories, group = 1), color = "blue", size = 1) +
geom_point(aes(y = Cumulative_Calories), color = "blue", size = 2) +
labs(title = "Weekly Calories Burned Waterfall Chart",
x = "Week",
y = "Change in Calories Burned",
caption = "Line shows cumulative calories burned") +
scale_fill_manual(values = c("red", "green"))
# Convert to plotly for interactivity
interactive_waterfall_chart <- ggplotly(waterfall_chart)
# Display the chart
interactive_waterfall_chart
